Interesting setup! Always a few kinks to work out. Back in the early 80's, father in law ran across an 18 foot Slickcraft, with a 4 cylinder Chevy/Mercruiser setup, that didn't get freeze plugs pulled for winter, so got the boat/trailer for a song! Put a 455 Olds, with Barr Marine water jackets on it, and 9inch exhaust out the back. Mercruiser outdrive couldn't handle the 455 though. Got a salvaged Mercruiser Alpha One, from a Cigarette, than burned in a marina fire, but outfruve was in the water. Then it was game on, with the stailess cleaver prop! Was hard to launch, as it was so rear heavy, so had to jam styrofoam coffee cups in the exhaust, to keep water out of the manifolds when launching. Dangerously fun, on a smooth lake (had to wrap your arm around the steering wheel BEFORE opening up the secondarys)!! Never got a true number on top speed, but with a 27 pitch prop, you KNEW you were cookin'!! Just had to take the opportunity to share. Y'all be creful and have fun!
New subscriber here. I'm just glad I stumbled across ur channel. I'm really excited for more boat videos to come. Def would love to see alot more boat content. But other than that great work and dedication towards the channel. Ur doing an awesome job. So with that much love to ya from Maryland❤❤❤.
Big Motor, little boat No beam width, Don't get Cocky for Speed. Wear a Life Vest On ALL RUNS, Tied to Kill Switch. The unkown Happen Quickly, BE prepared NOW. Good Luck.....
@@Gruin it's been in the water for 4 years. It's a 66" beam and it's very stable at WOT. I only wear a life jacket running up shallow strong current rivers
any flat water WOT run videos? Like the series and content. I have an 18ft v hull like this. Going to copy the hanging on the mic from the windshield support. You're also inspiring my to get out my old car audio gear for a 2nd Chapter. PPI, HiFonics and Focal components just collecting dust...
As far as your cooling system goes, Your water restriction is in the wrong place.. You said it's just after the water pump. That's not what you want to do.. You want the entire water system under pressure you need to place your restriction After the exhaust manifolds some place just before where the water goes overboard. You need to slow down the volume of water moving through the cooling system, give the water time to remove the heat from the block and exhaust manifolds.
Like I said in the video the entire system needed re routed at this point, and it has been. I originally had two gate valves after the engine, and I ended up putting them back on to restrict it just before the risers. I found out later that even with those valves almost all the way closed I still couldn't get even 100 degrees water temp. I'm not having a problem removing heat, I'm having a problem getting the engine to run any hotter than lake water temp. I ended up reinstalling a valve right at the pump and slowing it down ahead of everything to finally get some temperature
There's a big debate about it. Most people have thermostat housings so they run a restrictor plate to build pressure in the engine to keep air bubbles out. But most use a gate valve right at the pump to regulate temperature
Yeah the power is pretty good considering it's still running on the factory truck tune. You could definitely tell that with some tuning it would run much better it was very confused lol. And yes I planned on at least doing a mild cam in the near future. I have several 6.0s in the garage too so that's another option in the future if I wanted more power
That’s a good looking 4x4 square body w/hips you got there too! I’ve had 2 half tons and one 3/4 ton square body and I kick myself for selling them when I was in my early 20s….just HAD to have a new one at the time!
Nice job looks fun I'm doing a starcraft starchief over, wanting same motor set up one day. Has an old iron duke mercruiser 190 hp. Have to settle. Great looking boat you have.
Haha no I don't think so. Ol hips has been a great truck man. Daily drove it for ten years up until recently now it only gets used for work- towing trailers, hauling camper, hauling firewood
Those Corvette filter regulator work great when hooked to stock fuel pump its designed for. Dont talk crap if you don't know. I've used em on several vehicles. If you're using a non factory or jacked up pump don't use this regulator. Period.
@@disolejunk I used to use them all the time and I've had several of them fail. Not a serious regulator they're legitimately a POS and I'll never use one again. Doesn't cost that much more to buy a proper regulator
Yeah most are left hand steer because they have a gas pedal and they need room on the floor for it. I'm not a fan of gas pedals I like to set the throttle and cruise. My other jet boat a '78 Cobra jet also steers from the right with a hand throttle
thats not a gate valve so make sure its wide open , also consider the gps the motor actually requires . and maybe a thermostat. or heat exchanger. best wishes . mapbe a P C issue
Inboard boat motors and car engines are different. Boat motors have more torque and water manifolds. If you tried to put a boat motor in a car you will have problems overheating.
Don't know yet haven't ran it past 50 mph. I'll find out probably next season after the bottom gets finished, engine gets tuned and the pump gets rebuilt
No idea yet the bottom needs a bunch of work, the engine needs tuned and the pump needs a wear ring. Haven't ran it past 50 mph. We'll find out next summer

Cool boat but im here for the square body. What a beauty
I love the boat and the squarebody is killer
That is very nice 👍
A little off topic I'm sure but sweet ,Chevy. That thumbnail grabbed me from a mile away. Beauty

I have one of these old starcrafts and wanted to do an inboard on it, this is awesome!
I like that truck.😊
So cool to see this boat on the water. Can't wait til spring!
Thanks man I'm super excited to finish it up! This summer is gonna be fun!
@@roncook8566 Are you happy or surprised with the power? Do you have plans to hot rod the engine a little after everything is sorted out?
Yeah the power is pretty good considering it's still running on the factory truck tune. You could definitely tell that with some tuning it would run much better it was very confused lol. And yes I planned on at least doing a mild cam in the near future. I have several 6.0s in the garage too so that's another option in the future if I wanted more power
i’ll be looking 4 ya when the damns are fixed. awesome job on the boat my friend👍
Thanks budday! Looks like Secord might be the first one we get back
That’s a good looking 4x4 square body w/hips you got there too! I’ve had 2 half tons and one 3/4 ton square body and I kick myself for selling them when I was in my early 20s….just HAD to have a new one at the time!

Thank you! Can't wait to get it back out here shortly
A 190 hp iron duke 4 cyl ?
Iron Duke mercruiser are 140
You got a video on that pickup? Wow
Haha no I don't think so. Ol hips has been a great truck man. Daily drove it for ten years up until recently now it only gets used for work- towing trailers, hauling camper, hauling firewood
That is awesome!
How’s the boat?
Looks awesome! I have the identical boat and have been thinking of doing this to it. At this point how much money do you have into it?
Probably $3-4kish altogether?
This is really cool
Thanks man can't wait to get it out of storage soon. 65 hours on it now

Interesting you kept steering on right side. Most if not all jet boats steer from left. So how doesn’t it handle with engine torque? No foot pedal?
Yeah most are left hand steer because they have a gas pedal and they need room on the floor for it. I'm not a fan of gas pedals I like to set the throttle and cruise. My other jet boat a '78 Cobra jet also steers from the right with a hand throttle
Wow that Starcraft looks amazing. How fast do you think you were going?
I probably kept it under 45 mph. The bottom of the boat needs some more work before i try to get crazy with it
so if you get her up on the step then just back her down to where she stays there what kind of fuel economy do you think you're getting?
thats not a gate valve so make sure its wide open , also consider the gps the motor actually requires . and maybe a thermostat. or heat exchanger. best wishes . mapbe a P C issue
@@juanziegler1471 the valve at the pump? Yes that is a gate valve. This was three years ago everything is routed and plumbed totally different now
Ron I am doing the same thing. What Ecu did you use
Stock GM P01 and a truck harness that I reworked
@@roncook8566 wow that’s good I thought I would have to buy a after market ecu like a holly.
Inboard boat motors and car engines are different. Boat motors have more torque and water manifolds. If you tried to put a boat motor in a car you will have problems overheating.
Got a boat motor in my truck it runs great just saying😮😅😅😅
Any idea what your static draft is and draft on plane ?
Not sure what it is on plane but it's 12-13" static
How fast does it go?
Don't know yet haven't ran it past 50 mph. I'll find out probably next season after the bottom gets finished, engine gets tuned and the pump gets rebuilt
What exhaust manifolds are you using
They're small block Ford Windsor manifolds. I made adapters
@@roncook8566 nice job , so the port openings are spaced the same?
@@antfarmmining7824 very close to the same spacing yes. Port shape is obviously very different tho
@@roncook8566 thank you very much
What rpm and gps speeds are you getting??
No idea yet the bottom needs a bunch of work, the engine needs tuned and the pump needs a wear ring. Haven't ran it past 50 mph. We'll find out next summer
LS Motor and it’s not even fast 😢
@@jimmycline4778 how tf you know how fast it is chump? Never used any more than half throttle this entire video lmao
Looking quick to me, someone throw you out the boat you will be bouncing a few times on the water.
