That's a good idea using the mower diff. I was a bit nervous about running the power thru that as well but looks like the locking system will solve that!
I’m hoping the diff idea will work! Haha cyber truck, I want to bring the sides up because there will be a lot of water splashing up it should also make the whole boat more ridged
I love polar opposites of fabrication and machining. Beautiful turned face one minute, then that crazy grinder belt driven rig, then to the shaft welding setup. There is always a way of making it work.
I love shed life too . I into Windmills and Campavans. My Windmill use smat driver. I live in Matamata. LOVE to help you out , Douglas Keep on Inventing.
Lift and lower with your knees, not your back. I was getting sore watching you lug that engine around. Your camera work and editing are absolutely excellent
Will you have enough RPM to dive the jet pump? Engine is geared down 4:1 through clutch basket gear drive and gear box. I did a similar thing with a motorcycle engine in a boat and had to delete the clutch basket. Replaced with a chain drive at 1.5:1. Cheers
I’m hoping in top gear it will be fast enough , I guess I could gear it up with a chain and sprockets if needed but need to use the gearbox for the wheels as well
@@DktheWelder You’d almost want to have the engine going to the wheels first, then have a chain geared to the jet pump. So you can play with ratios, also you can add a way to disengage the pump so it’s not running dry while on land… but awesome work man. Love this idea, and how you approach problems.
While too small for this 90hp, for a smaller/slower project a cheap mower transaxle will work nicely. Once you take one apart you will see a stack of gears with couple of sliders in keyways on one of the shafts that engage/disengage each set of gears. On one side of that set is a small chain, that's reverse gear. After that there is a massive gear reduction that goes into a differential. In racing mowers that reduction is taken out, or at least increased for higher speed on the output. Also all bronze bushings are replaced with bearings, just for longevity. Speaking of bushings, that is most likely what your differential has as well, so check it out and do put bearings in so that it doesn't chew itself up at speed in neutral/reverse. If you get a hydrostatic transaxle, it will look practically identical, but on the inside it would have a small cylindrical wobble-plate CVT instead of that stack of gears. It's great since it's stepless FWD-REV that also serves as a brake for the machine. Not really useful for something that goes fast, however two of those units might make for a neat tank-steering-type system. Just one with no gears could be an interesting way to drive a boat prop. As for front, what about a torsion front axle? Low profile, and the whole thing can be pivoted via the torsion spring itself to raise/lower front wheels. Even if the 'torsion spring' in this case is just a torsion shaft with a bracket and conventional spring suspension/lift system in the middle, it should still work nicely.
I had a lawnmower gearbox in it before going to the big engine and jet drive and had a 15hp motor it worked well but too slow on the water I have a video on my channel. I have also made a mini tank using a transaxle gearbox also on my channel 👍thanks for the detailed comment you have a lot of knowledge on those gearboxes
@@DktheWelder Ah yes, forgot about that one. That was a really good transmission as well since it did not have that really high reduction on the output. Nice tank by the way!
Say I just watched your video. The differential. Is somewhat common. I had on a 1974 Tri Sport Alsport. They came with 8hp kholers to 40hp 2cycles Rupps . I put 350 CB Honda on mine 7 inch disc hyd. Brakes. Geared it to top out at 55mph.. it was beyond wild. Flat tracked like crazy.. they hold up well. Not to sure of all the weight you're hanging on it.. But I've found the some of those China quads have F-N--R cast cast together. But I was able tu saw-all the engine from the gear box it was an adult size torque converter style so it has an exposed shat input the sprocket to drive the the quad. I enjoyed your video very much. Where are you located.. I've got way to many projects. 2 of those Tri sports. Once with a 75 hp Polaris with a Hi- Lo-Rev. Of a Polaris 4x4 quad stuffed down in the frome. Then the other with a Honda 600 100hp hanging on the other. And at least 10 pluss other gas powered from mini fork lift off road. I'm getting to old for all these. I put that Honda 350 on the first Tri Sport back in 1974. While stationed in Hawaii I've got to go back an see why I subbed . Builder never stop building. Take care.
@@donaldpowers5557 o thanks I haven’t seen those little diffs like I am using before, sounds like you have built a lot of stuff! I’m in New Zealand , waihi
Make a small sleeve that fits on the jet pump drive side of that sloppy spline so the drive shaft slides over the splines and then centers on the sleeve
I am glad you got the rubbish out as it would drive me nuts too. Awesome build like what your doing.
I always have too many projects on the go and parts of things everywhere I need to work on my cleaning a lot more haha
the world does not have enough homemade "lathe" build montages.
I work on a 30' Jet Drive Fire Boat. It was my 1st intro to a Jet Drive , I love 'em. Keep up the Awesome work!!
I love your ingenuity and your thought process in making things work from bits and pieces.
That's a good idea using the mower diff. I was a bit nervous about running the power thru that as well but looks like the locking system will solve that!
That future design is looking suspiciously like a cybertruck
I’m hoping the diff idea will work! Haha cyber truck, I want to bring the sides up because there will be a lot of water splashing up it should also make the whole boat more ridged
Nice work again!👊🏻👊🏻Waiting to see this thing in action😎
Thanks. It will be a while have a lot to do ! Plus full time work and kids and everything, really like your new project 👍
I love polar opposites of fabrication and machining. Beautiful turned face one minute, then that crazy grinder belt driven rig, then to the shaft welding setup. There is always a way of making it work.
Making stuff with all the proper tools is easy , it can be more fun doing it the hard way haha
Great project. Love the progress and planning
Love the Three 6 mafia beat aha. And killer engineering. Love how everything you did can be built at home with modest tools
I love shed life too . I into Windmills and Campavans. My Windmill use smat driver. I live in Matamata. LOVE to help you out , Douglas Keep on Inventing.
Such a great project!
It is a lot of but hopefully really cool in the end
Lift and lower with your knees, not your back. I was getting sore watching you lug that engine around. Your camera work and editing are absolutely excellent
That motor is 67 kg 145 pounds hopefully I don’t have to lift it many more times haha. Thanks 👍
love this channel its kiwi to build it with whats in the shed + new shape on the jet intake, nice.
Just got to use what I have haha . Thanks
Brother you got so much ingenuity I like that shed life to man keep doing it brother love the videos
Cool work, looking forward to the next video
OMG Just Found you on youtube!!! 2 mins and I was hooked!! I love this shit !!
Awsom man, its coming together nicley.
Damn fine work man!
Good to meet you. Subscribed
Nice. Maybe you need an extra support for the water jet axle. I think it's going to be a bit floppy. Keep up the good work.
Yeah I think it will be a problem I will try sort it out

Awesome video Daniel surely you're a UA-cam millionaire by now?
Thanks, na I’m not getting that many views at the moment

I've got to go back an see why I subbed . Builder never stop building. Take care.
@@donaldpowers5557 o thanks I haven’t seen those little diffs like I am using before, sounds like you have built a lot of stuff! I’m in New Zealand , waihi
@@DktheWelder I did go back all look and see why I subbed it was the Trike thing. Because of the I had
nice work man i like it .
Don't know if anybody has said but maybe a brake caliper to clamp the sprocket for reverse
I was thinking of that but the disc will be in the way of the 2 half’s when in forward mode
UHM....
You might need some WHEELIE BARS with that engine...!!!!
It’s pretty long I don’t think it would wheelie but would be awesome if it could
Tuck the front wheels in. It will never be a street able cruiser brother. Put a small fender on it if you have too and make it strong. Thanks 🙏
Haha it won’t be on the streets, I want to put two wheels on the front but haven’t figured it out yet
Make a small sleeve that fits on the jet pump drive side of that sloppy spline so the drive shaft slides over the splines and then centers on the sleeve
Yeah I thought of that but the spline part is stepped bigger. I could maybe make what you say but split in half
@@DktheWelder a split 2 piece 1 would work fine
This is cool as we're are you going to use this
There is a huge area of tidal mudflats near where I live which also has access to shallow rivers 👍
Right on!
Thanks drift king
Good
Mantap salam kenal dari indonesia
Your so cool
I don't think I've ever been this early hahaha
