You guys should definitely do the heat insulation padding under the engine cover /backseat and hear wrap the exhaust that's gonna heat that cover up tremendously
It won’t help, all boats/jetskis have water running through the exhaust for a reason . It would be simple to drill and tap exhaust with a small nozzle/nitrous jet spraying water into it. Every boat I’ve owned you can put you hand on the exhaust while running and not get burned
They should send the exhaust after they build the turbo kit to the place Taylor ray sent the turbo kit for his corvette to and have them make a heat shield
Put a latch on the back seat to hold it in place while jumping logs and rough waters. Seems like it would try to hinge up and down while things are getting wild.
Put thermal wrap on the exhaust, pipe and muffler to keep the heat in the pipes, because that seat is going to get hot. Can’t wait till you race Cleetus 🔥🔥🔥🔥🔥
I'd hate for the engine cover/rear seat to fly up while towing it. I'm sure the boat windshield should keep the wind from lifting it but a good bounce at 60 mph might pop it up for the wind to catch it
Still need to get your lights installed so you don't get popped by the sheriff. Would also add some heat shield to the bottom of the rear seats just to help a bit more
You should look into what Taylor Ray did with his exhaust and how he got it professionally wrapped. It looks sick and helps ALOT with exhaust temps. Obviously you would send it out once the turbo kit is done. Love the boat build
Dont forget to put an air inlet to the engine compartment The fan is an outlet and depending on how well the cover fits you may choke the engine out. We did it on a boat years ago and it took ages to work out why it would run a few mins then stop but run well with the cover up. I doubt there is enough room around your exhaust exit
Flip that fan around so its pulling air into the engine bay and pushing it out the exhaust cut out because at the moment it will be pulling air in around a hot exhaust. Other than that this is a clean jet boat build!
You guys should add a plexiglass window right between those rear seats so we can all can admire the beauty of the K series at all times! Maybe even some neon lighting in there!
Been following for years, and absolutely love the content and planning on building my own k series in the near future, if you guys ever plan on coming to summernats in Australia please let it be known so i can come meet you guys!! Love the work
Great seeing this project coming together, and I'm really looking forward to the turbo version! The one point I would make is regarding the fan/venting arrangement, pretty much every power boat I've seen or worked on over the years has at least one extractor right at the bottom of the compartment, I was told this is because most fuel vapours are heavier than air. I also think some of the other comments regarding sound deadening/insulation on the underside of the seat are good ... as for the exhaust its temporary .. wrap it when you do the turbo install .. also totally agree with using the resonator .. straight exhaust on a boat will get old really quickly :)
I have a trailer modification suggestion; you both are great fabricators so you shouldn't have any proiblem cutting and rewelding the cross members of the trailer to match the cross sections of the boat bottom. Then you can lower your stringers thus allowing the boat to sit lower in the trailer. That will make launching and loading your boat much easier and you won't have to back so deep into the water, especially if you are using the Hatch to tow it with. Its something you can do in a day or two and you won't regret it. Have fun!
I like this project. It always seems a vehicle is just for the channel when Kyle buys one. I like how this is also for him to enjoy. Mans deserves it. Lol.
I think it'd be worth spending some time to clean up the inside of the intake manifold. That angle will at very least increase the turbulence of the air passing through. As you mentioned, it's a bit rich afterwards.
One vent should be inlet one should be outlet please don’t blow it up lol they also make scoops to force air in and out so you don’t need to run blowers 247 just at idle
bro i been watching you for years i love every content you do just recently my girl pass away from stage 4 cancer just 2 weeks ago she used to watch your utube also with me she told me to set up my own shop as well but I'm not in that place anymore i continue to watch your great work everytime you put out your content keep up the great work your doing inspiration is what everyone needs even though sometimes life throws you a curve ball thank you Kyle i will continue watching along side my girl in heaven god bless you bro
Hey Kyle and Wyatt so glad to see that you un ghetto the jet boat LOL Seriously awesome job guys can't wait to see the MR2 back at the track making passes
Maybe some rubber feet/pads for the engine cover so the people sittingwon't be vibrating to death. Also maybe a way to lock it down so if they become airborne it wont pinch feets or toesies.
It might be interesting to find out if Cleetus still has one of those little electric Turbos and throw on there to see what happens, did not take much fab work.
Hey kyle thanks for showing love out here in Bakersfield Famoso Raceway. Didnt even hesitate to take a pic with me and my son and talk for a sec real ass dude! Og subscriber here btw
Since your pulling all of the air out of the engine bay,your gonna need a way for it to get back in. Back in the day you could feel the seat sycking down on jetskis from being to air tight. I would drill holes on the sides,and bottoms of the cups holders,and maybe weld a deflection plate under it to not allow any water to drip right under it.
The bilge fan needs to have a hose to the bottom of the bilge as gas fumes are heavier than air and fumes can still accumulate there potentially causing explosion. Great build!
If you aren’t doing the foam floor like Cleetus, grab some weatherstripping for the engine hatch… sounds like that thing will rattle against the floor and drive you nuts 🤣
Go ahead and get 2 more vent grills to mount on the rear seat frame between the seat and floor or in front of the engine between the seats so if fuel vapor is present thats the first place fresh air pulls by, 2 fans pulling with no where to draw fresh air they will stall after a few seconds…ours did and you could hear the sound change. We hard mounted our fans to the rear vent housings with road tractor intercooler hose so they were up and out of the way
Nice work as always guys! I’m from Dunedin, New Zealand where your Scott jet pump comes from! Anyways, I’m an engineer and we’re taught when working in a confined space you want to pump the fresh air in instead of suck the bad out. You’ll need to have somewhere for the air to go but pushing fresh cool air into the engine hold will be far more effective than sucking the hot air out. Keep up the good work.
Would recommend putting a vent for fresh air below the cup holders in the back. Fresh clean air in with the vents you put in the back. Help with cool clean air.
Looks awesome! Not sure how close it is in person but might move the trim switch a little further away from the switch panel, when bouncing around and trying to trim you might bump a switch you don’t want to, the boat looks awesome! Can’t wait to see it boosted boiz!!💪🏼
I’m so stoked on this build. I’m glad the vision is nearing completion. I really want to see this thing making 550 hp doing 80 knots on the water 😂. Sick!!
Rubber weather seal the edges of the cover and turn the fan the other direction so its pulling cool air into the bay and pushing it out around the exsaust. Will keep the fan from overheating with engine temps. The weather strip will keep hot air from blowing on the passengers throught the cracks. Fan will live longer. Mount it directly to the vent, without the hose. You will pick up cfms.
it might be enough with weight in the seats (people), but when you are going over wake at high speeds without people in the back seats it might get a bit crazy. you might want a way to secure the hinge cover to the floor of the boat.
I’d add 3 vents if you are gonna end up using two of the vents as “exhaust” & fume vents (PC version of exhaust), have one to allow it to maintain equal pressure
Boat is looking good, can't wait to see it turboed! Like some others have said...use some quilted silver heat wrap insulation on the the inside of the back seat's/engine cover hatch, some of that heavy duty clip on edge protector stripping on the leading edge and some latches to keep it down tight and from making hella noise while banging around on waves and over logs.
All my jet boats have had air inlet scoops up top facing forward to feed fresh air for the engine then at least 2 in back for exhaust of heat and fumes. You need inlet air , especially if you turbo or it will starve at speed. Can't wait to see it hauling on the river !
Important!!! Fuel vapors sink to the lowest part of the hull. There should be a hose coming from the inlet side of fan down to the bottom of boat. You can just lay it under the driveshaft. Run the fan for a few minutes before starting. Be safe guys!
Looking Real good! You only need one blower, one vent in one vent out, fan sucks fresh air from outside, discharge hose to the bilge, gas vapor is heaver than air so that will blow out fumes. Run 2 to 3 min. after fueling, I've seen 2 jet skies that were on engine cover of a crusier, one went all the way across the slue (bout 200') and the captain went to the hospital with flash burns. Don't have to run when moving, but you have 2 run 2 vents on top of engine cover, one pointed forward and one back, one on each side then you can turn off the blower. Oh if you been sitting a while run the blower for a few min. before fire up. I think we all want the next episode! Ret. USN, River Rat.
Your final design should incluse extending that blowe fan ducting as low as possible in the bilge. Gas fumes sink so the intake side of the blower needs to be as low as possible. Also, your starter and alternator really need to be updated to SAE J1171 ignition proof spec.
For the rear, aluminum engine cover, I'd recommend some Honda Accord Wagon rear trunk lift gas struts. They're affordable($10.99/ea), available everywhere and excellent at lifting ~15-20lb weights. I used two for my CF hood and they're more than adequate. Throw is about 14.5" extended.
I'm a marine tech in Australia and think you guys have killed it. My only advice would be to look out for electrolysis of the aluminium. Make sure you dont!! earth anything to the boat. All earths should go back to either the battery, engine or a bus bar. When using stainless and aluminium together in a marine environment the stainless will also cause the aluminium to corrode. I use tefgel on all my screws and bolts and sikaflex as a gasket between aluminium and other metals. Sacrificial anodes are also a great idea not only on the boat itself but the jet pump and the engine. These are normally made of zinc and will corrode before any other metal on the boat.
Great work as usual. You guys put a lot of work into these projects and I appreciate it. I've loved your content for a few years now I love the Honda stuff and now the LS stuff. Wow!! Horsepower is the object and you're doing it .I also like the way you include the mistakes you make. That's how we all learn. Thanks for the hard work!!
17:18 The rear seat unit seems to be tilted up slightly...some trimming to the floor or the seats maybe? The little details...glad to see the boat getting a big sand trap! And as everyone said...can't hurt to have latches on each front corner of the rear seats like ricer bumper latches or something
Jet boat is coming along nicely! May I suggest placing the bilge blowers as low as possible in the bilge. Fuel vapors are heavy and like to hang out around the starter motor :)
I think the comments speak for themselves guys, wrap your exhaust so you don’t melt seats and asses. Put a latch so it doesn’t fly up on the road or while jumping stuff. Headed in the right direction, keep it up!!!!
That rear seat hood is sick! You should get some stuff to make it legit like heat skin/sound deadening the inside and something nice so it latch’s like catch latch or even a hood latch that the driver has release for. Put some threaded bumps so it shuts nice like a car hood. Maybe smooth the bottom edge Either cushion it or have some sort of skin cushion to match the front seats. Just tossing ideas but, Love watching the jet boat videos keep it up 👍
That Engine cover is going to get hot in that Florida sun. For the exhaust out the back. Most jet style boats the exhaust exits near the water line to help lower exhaust noise. Can you take the plate off a junk jet ski and mount it into your boat to tie the exhaust into? The resonator did help with the noise level but after an hour of full throttle the person in the back seat on the right side it will still be quite loud.
Should chuck some clasps from like a metal toolbox on the rear seats so it doesnt bounce up and clip someones heels when ya hit waves and objects. looks great guys!
Add a row or 2 of louvres around the base of the rear seat/engine compartment hatch or at least some way for cooler air to enter. Allowing the colder air to pass up over the motor will greatly help with engine and component heat soak and also keep a constant supply of fresh air moving through it.
If your going to add a second blower make sure you put a third vent hole in all boats only use one blower and the other vent is to let fresh air in so just make sure you got one to let fresh air in
Love the fact you made the intake manifold work...... love everything you guys are doing! You guys are my favorite channel on youtube ! Keep doing what you do !
When your done with the hot side you should ceramic coat everything to keep ALOT of heat out of the bay, it works amazing, we have the headers coated on the race boat and that is a blown bigblock making 2200hp and you can almost put your hand on the headers after a run it blows my mind
With a turbo you should you should try to get the intake out of the back seat/engine cover. It would need to be covered so it is almost like a mini snorkel. It would keep intake temps down a lot when the turbo is causing so much heat.
When you make 2 vents blowing hot air out i would suggest you make 2 vents at the rear seats at ankle height to let fresh air flow in from the front to keep it cool down there.
Put two DC fans on the front of the seats console sucking fresh air in to the engine bay and a welded cover over the openings and at the bottom the in let have the ecm cycle one before start up two running at full stick .Small engine with turbo in an engine room should be at positive pressure for cooler intake temperature it will do more then just this . This will solve lots of problems you MAY have down the track.
Kyle put one vent that you have just below the cup holders on the seat cover and you wont need a blower fan to pull air out since it will be doing it automatically and some heat reflective tape inside of the cover should help with heat management
Only need one bilge blower. You are going to need to figure out how to get more air into the hatch as it looks pretty solid on the front part of the rear seat. It’s going to starve the engine of fresh cool air. Couple billet vents in the front and perhaps a centered one in the back. Check out cp performance. Cool build!!
The job is looking great dudes but I would suggest moving your Exhaust end halfway down so people don't burn their arm trying to grab the hand rail at the back of your boat 😁👍
Add Butyl sound deadener to AS MUCH of the engine compartment as you can. 50-80 mil all on the backside of the seats/engine cover and as much on the sides of the boat in the "engine bay" will do TREMENDOUS amounts of sound deadening and heat resistance.
I personally would install Butyl and then Closed Cell Form sound deadening ON TOP of Butyl in the engine bay to sufficiently quiet overall ambient noise from the boat.
Should do a little exhaust flap on the tail pipe. Not water or sand will get inside. The sun is gonna roast the seating area. Nobody will be able to sit on those, it won't be the engine heating it up. I learned the hard way on this.
I would probably put a secondary bilge pump, one that you can trigger with a switch... Maybe like some sort of high flow unit, in case you get swamped or buried..
As a boat builder my self i think is better if u put then vent one pushing air in and one pushing air out..the engine room will be more cooler
Exactly!
One intake one exaust.. that's how it works
The intake will be pulling air from around the exhaust as it is haha
Yes I was thinking the same thing, circulation will but alot cooler
I enjoy of your boat building videos on your channel.
There’s room for an intake on the front middle part between the seats
You guys should definitely do the heat insulation padding under the engine cover /backseat and hear wrap the exhaust that's gonna heat that cover up tremendously
When the turbo kit gets installed would be amazing to do the heat guard like Taylor Ray has on his Vette!
They should get it done by the same guys that did taylor rays corvette.
It won’t help, all boats/jetskis have water running through the exhaust for a reason . It would be simple to drill and tap exhaust with a small nozzle/nitrous jet spraying water into it. Every boat I’ve owned you can put you hand on the exhaust while running and not get burned
They should send the exhaust after they build the turbo kit to the place Taylor ray sent the turbo kit for his corvette to and have them make a heat shield
Yup and its gonna keep some of the sound in.
Put a latch on the back seat to hold it in place while jumping logs and rough waters. Seems like it would try to hinge up and down while things are getting wild.
Ejecto seato cuz
He should use a Honda hood latch mechanism
I was just about to make the same comment but I saw it was first on my list. lmao
Everybody knows you load up a couple of fat girls to hold the seat down
or electronic engine hatch lifts
The vents... one is an inlet and one is an outlet.. you need fresh air to replace the fumes you suck out.. blower on outlet side, pushing outward
Put thermal wrap on the exhaust, pipe and muffler to keep the heat in the pipes, because that seat is going to get hot. Can’t wait till you race Cleetus 🔥🔥🔥🔥🔥
He's going to destroy cleetus.
I'd hate for the engine cover/rear seat to fly up while towing it. I'm sure the boat windshield should keep the wind from lifting it but a good bounce at 60 mph might pop it up for the wind to catch it
Lol dont u see how heavy that thing is?
very true, good idea for a latch for the rear seats/engine cover
Facts
air brakes are cool tho,,,, everyone else will just fly right by them lol
The windshield will actually create a low pressure area in the boat, lifting the engine cover.
Still need to get your lights installed so you don't get popped by the sheriff. Would also add some heat shield to the bottom of the rear seats just to help a bit more
You should look into what Taylor Ray did with his exhaust and how he got it professionally wrapped. It looks sick and helps ALOT with exhaust temps. Obviously you would send it out once the turbo kit is done. Love the boat build
You need to put the blower in the bottom of the hull, or run a hose from the suction side down to the bottom. Flammable vapors are heavier than air.
Dont forget to put an air inlet to the engine compartment
The fan is an outlet and depending on how well the cover fits you may choke the engine out.
We did it on a boat years ago and it took ages to work out why it would run a few mins then stop but run well with the cover up.
I doubt there is enough room around your exhaust exit
Flip that fan around so its pulling air into the engine bay and pushing it out the exhaust cut out because at the moment it will be pulling air in around a hot exhaust.
Other than that this is a clean jet boat build!
A Cleatus upload immediately followed up by a BoostedBoiz upload. Hell Yeah Brother!
You should put a 12v linear actuator on the rear seat to lift it.
Could also be used to dump passengers off the back.
Smoking a fat ass blunt watching my favorite car guys. Been a fan since Charlie days.
Perfect timing just finished Cleetus' video👌👌
You guys should add a plexiglass window right between those rear seats so we can all can admire the beauty of the K series at all times! Maybe even some neon lighting in there!
Been following for years, and absolutely love the content and planning on building my own k series in the near future, if you guys ever plan on coming to summernats in Australia please let it be known so i can come meet you guys!! Love the work
Great seeing this project coming together, and I'm really looking forward to the turbo version!
The one point I would make is regarding the fan/venting arrangement, pretty much every power boat I've seen or worked on over the years has at least one extractor right at the bottom of the compartment, I was told this is because most fuel vapours are heavier than air.
I also think some of the other comments regarding sound deadening/insulation on the underside of the seat are good ... as for the exhaust its temporary .. wrap it when you do the turbo install .. also totally agree with using the resonator .. straight exhaust on a boat will get old really quickly :)
I have a trailer modification suggestion; you both are great fabricators so you shouldn't have any proiblem cutting and rewelding the cross members of the trailer to match the cross sections of the boat bottom. Then you can lower your stringers thus allowing the boat to sit lower in the trailer. That will make launching and loading your boat much easier and you won't have to back so deep into the water, especially if you are using the Hatch to tow it with. Its something you can do in a day or two and you won't regret it. Have fun!

One vent should be inlet one should be outlet please don’t blow it up lol they also make scoops to force air in and out so you don’t need to run blowers 247 just at idle
Nice progress!! The intake manifold would benefit from a little porting to smooth out the inside of those welds👍
Cool boat. Dynamat or insulate the bottom of that passenger seat.. cause I can imagine the seats gonna get so hot. Love the build good job dudes
bro i been watching you for years i love every content you do just recently my girl pass away from stage 4 cancer just 2 weeks ago she used to watch your utube also with me she told me to set up my own shop as well but I'm not in that place anymore i continue to watch your great work everytime you put out your content keep up the great work your doing inspiration is what everyone needs even though sometimes life throws you a curve ball thank you Kyle i will continue watching along side my girl in heaven god bless you bro
Hey Kyle and Wyatt so glad to see that you un ghetto the jet boat LOL Seriously awesome job guys can't wait to see the MR2 back at the track making passes
It’s way better to have the blower drawing out of the bottom of the bilge. Gas fumes always sink to the bottom of the hull. Enjoy the build progress.
Straight edge that intake flange, every intake I’ve done this too always warps, just needs a quick cut to fix it
Maybe some rubber feet/pads for the engine cover so the people sittingwon't be vibrating to death. Also maybe a way to lock it down so if they become airborne it wont pinch feets or toesies.
It might be interesting to find out if Cleetus still has one of those little electric Turbos and throw on there to see what happens, did not take much fab work.
Hey kyle thanks for showing love out here in Bakersfield Famoso Raceway. Didnt even hesitate to take a pic with me and my son and talk for a sec real ass dude! Og subscriber here btw

If you aren’t doing the foam floor like Cleetus, grab some weatherstripping for the engine hatch… sounds like that thing will rattle against the floor and drive you nuts 🤣

This is an excellent suggestion. Hope the consider it.
Check out some sort of door seals, for your motor bay, and some latches to keep it down and sealed.
Wow, that thing looks amazing so far! Well done guys and can't wait for the turbo install!
I’m so stoked on this build. I’m glad the vision is nearing completion. I really want to see this thing making 550 hp doing 80 knots on the water 😂. Sick!!

You may want a wing over top, like the tow rack on some boats,because this is going to Fly !
Your videos are not long enough! Jesus I wait so long for you guys to put out a video and then they are so short!
Important!!! Fuel vapors sink to the lowest part of the hull. There should be a hose coming from the inlet side of fan down to the bottom of boat. You can just lay it under the driveshaft. Run the fan for a few minutes before starting. Be safe guys!
I'd highly suggest getting those bash bars on. Simple project, and will be so worth it. Love the K swap jet boat!
Looking Real good! You only need one blower, one vent in one vent out, fan sucks fresh air from outside, discharge hose to the bilge, gas vapor is heaver than air so that will blow out fumes.

If you add another fan then you will need to run another vent. Or one pushing and other pulling air. Heat wrap your exhaust too. Otherwise great job !
That looks like a fun machine.. with lots of time, and amazing ideas put into it... Your cool... congratulations on your build gentleman.
Can't wait to see that turbo jet boat with 500hp or more. That thing is gonna fly!

It’s 1:17 am in the UK I’ve just come back in from racking my own brain and doing very little other than think and this pops up 😅
Great work as usual. You guys put a lot of work into these projects and I appreciate it. I've loved your content for a few years now I love the Honda stuff and now the LS stuff. Wow!!

And as everyone said...can't hurt to have latches on each front corner of the rear seats like ricer bumper latches or something
What an Awesome build...great job guys, Me likey!! Maybe add some heat shielding to the underside of your seat lid.
I think you might want to add a kick panel for your feet under the dash. Looks awesome can’t wait to see it rip!!
Nice boat!! Can't wait to see you guys rippin it up some nasty rapids in Idaho next year!!!
It’s looking really good. Glad you’re working on this.
Jet boat is coming along nicely! May I suggest placing the bilge blowers as low as possible in the bilge. Fuel vapors are heavy and like to hang out around the starter motor :)

Either cushion it or have some sort of skin cushion to match the front seats.
Just tossing ideas but,
Love watching the jet boat videos keep it up 👍
That Engine cover is going to get hot in that Florida sun. For the exhaust out the back. Most jet style boats the exhaust exits near the water line to help lower exhaust noise. Can you take the plate off a junk jet ski and mount it into your boat to tie the exhaust into? The resonator did help with the noise level but after an hour of full throttle the person in the back seat on the right side it will still be quite loud.
Heat shield the back seat and latches for the seat cover also.... Looking good Boiz!
When you take it on the water...after 15 min we'd love to see a FLiR cam shot of that back seat.
The hatch is the new jet boat tow rig period they look so good together!
Gonna need some air intakes on that seat/cover for the fans to do anything.. badass build, guys!
Dude! That looks so good Cleetus is gonna flip when he sees this gonna get that Jet boat fever again
Should chuck some clasps from like a metal toolbox on the rear seats so it doesnt bounce up and clip someones heels when ya hit waves and objects. looks great guys!
Add a row or 2 of louvres around the base of the rear seat/engine compartment hatch or at least some way for cooler air to enter.
Allowing the colder air to pass up over the motor will greatly help with engine and component heat soak and also keep a constant supply of fresh air moving through it.
If your going to add a second blower make sure you put a third vent hole in all boats only use one blower and the other vent is to let fresh air in so just make sure you got one to let fresh air in
Love the fact you made the intake manifold work...... love everything you guys are doing! You guys are my favorite channel on youtube ! Keep doing what you do !
When your done with the hot side you should ceramic coat everything to keep ALOT of heat out of the bay, it works amazing, we have the headers coated on the race boat and that is a blown bigblock making 2200hp and you can almost put your hand on the headers after a run it blows my mind
With a turbo you should you should try to get the intake out of the back seat/engine cover. It would need to be covered so it is almost like a mini snorkel. It would keep intake temps down a lot when the turbo is causing so much heat.
The second vent fan should be an in vent so one is drawing cool fresh air in and the other is pumping hot potentially hazardous air out
Dude you guys are solid. Youve come a long way. Mind body and spirit brother, stay at it.
When you make 2 vents blowing hot air out i would suggest you make 2 vents at the rear seats at ankle height to let fresh air flow in from the front to keep it cool down there.
Clear screen on the top of the back seats so people can see the mottor and easy to inspect when on the watter
Put two DC fans on the front of the seats console sucking fresh air in to the engine bay and a welded cover over the openings and at the bottom the in let have the ecm cycle one before start up two running at full stick .Small engine with turbo in an engine room should be at positive pressure for cooler intake temperature it will do more then just this . This will solve lots of problems you MAY have down the track.
Kyle put one vent that you have just below the cup holders on the seat cover and you wont need a blower fan to pull air out since it will be doing it automatically and some heat reflective tape inside of the cover should help with heat management
Speakers and radio. By the cup holders on the back seat put speakers below it.
Can't wait to see a hood exit come through the cup holders...2 stepping in the face of the rear passengers 🤣
Water cooling the exhaust will definitely help with the heat management. Easy peasy just weld a bung and stick a fitting in.
Only need one bilge blower.
You are going to need to figure out how to get more air into the hatch as it looks pretty solid on the front part of the rear seat.
It’s going to starve the engine of fresh cool air.
Couple billet vents in the front and perhaps a centered one in the back. Check out cp performance.
Cool build!!
The job is looking great dudes but I would suggest moving your Exhaust end halfway down so people don't burn their arm trying to grab the hand rail at the back of your boat 😁👍
A bronze garden hose attached at the rear to hook a hose to to cool the engine and or flush it when out of the water may help
Kyle is literally in the hot seat!! You really should add some of the gold heat shielding to the underside of the rear seats!
Definitely use one of those vent fans for intake and one of the vent fans for exhaust. You need an intake in and out for flow
Add Butyl sound deadener to AS MUCH of the engine compartment as you can. 50-80 mil all on the backside of the seats/engine cover and as much on the sides of the boat in the "engine bay" will do TREMENDOUS amounts of sound deadening and heat resistance.
I personally would install Butyl and then Closed Cell Form sound deadening ON TOP of Butyl in the engine bay to sufficiently quiet overall ambient noise from the boat.
Don't forget to add intake vents somewhere as well. Motor is going to need a ton of air, especially after you add the turbo kit.
Should do a little exhaust flap on the tail pipe. Not water or sand will get inside. The sun is gonna roast the seating area. Nobody will be able to sit on those, it won't be the engine heating it up. I learned the hard way on this.
so keen to see it done with the trubo kit and fully wrapped
Add heat protection to the engine side of the rear seat hatch, will stop passengers getting third degree burns lol 🤣
I would probably put a secondary bilge pump, one that you can trigger with a switch... Maybe like some sort of high flow unit, in case you get swamped or buried..
I have enjoyed the Jet Boat build! Well done guys.
