Chainsaw Powered Surface Drive ,Build and Test ,Stihl 088 

This gent is only at 13k subs, like how is this even possible? Glad that I found this gem of a channel. Really enjoy the content, man!

Your ideas at the end are great (the expansion chamber for more power and exhaust tip below surface, the flywheel to make it not stall as much, and of course a longer stick for more balance and more control) impatient to see this Lil boat on flat water going for a rip

You’re having the stalling issue because the chainsaw doesn’t make much torque, when the prop bites it doesn’t have the torque to spin it. I run a belt drive v twin on my surface drive in my big boat and when the props torque up you’ll feel the motor drop rpm and you’ll feel the boat Jump forward pretty hard. Good to see you got it working toward the end, you build some really neat stuff!

100th of a Meter...Gold!

NZ must be a great place.

There must be videos about tuning chainsaws. I used to watch Buckin' Billy Ray Smith who is a tree feller on Vancouver Island, and he uses several tuned McCulloch chainsaws, but does not do the tuning himself. I guess chainsaws only do their thing while running flat out, so are not designed to have any sort of a broad powerband. In fact they would pretty much definitely stall if the bar hits the tree at anything less than flat out, and I have no idea what you could do to change that. It's a very long time since I raced two strokes. In fact we used to call it Scrambling then, and not Motocross, but from what I remember, lower crankcase compression and a longer inlet manifold were supposed to produce a broader powerband. If you had a spare piston you could maybe try shortening the skirt to lower crankcase compression, but I can't thinking that it could all go horribly wrong and it would hardly run. That was the fastest we've seen the boat run though, so you seem to be going in the right direction.

Sometimes the old methods of propulsion are the best ones

"10mm plate or if you imperial that's one hundredth of a metre" 🤣🤣🤣🤣 cracked me up bro 🤣🤣 ❤️love your vids I just stumbled on your channel and am stoked I did ❤️🤜🤛nice build bro🤜🤛 she looks like a ripper💪😎

😂typical kiwi! Mad as a cut snake! Love it mate, absolutely sweet!

Love your enthusiasm mate! Keep those videos rolling brother!

Yeeea keen to see it on some flat water

I think maybe because you've removed the clutch she kept stalling, love ya videos mate awesome

Good one brother. I just realized your in NZ my cousin and her family live in Timaru. Her husband is Dean Broadhead he’s a sparky! I enjoy watching your tinkering so much. I have a shipping container I turned into a work shop I am retired after 40 years as master Electrician! Keep up the great videos!

I was looking for somebody to do this in youtube. I was planning to do seascooter with lightweight 2 stroke engine. This stihl 088 look great with high rpm high hp Light weight.

Going to burn the saw up with the cover off! Needs it to channel the air over cylinder

Nice build mate

I guess it would be a fun project. But just buy a small outboard. or use a small electric that can run all day.

That thing was cruising with the last prop. Try not to get yourself washed away and drowned. Glad to see you were wearing a life vest

Sick! I would of popped down for a look! 😂😂

Probably need a clutch to prevent stalling

think you should go to a 2cyl or a healthy single cyl would be ok to ,.. 2 stroke with a CVT drive set up...if you used your cv axle idea i think you could make it work with your surface drive you want.. you wouldn't have to worry about power and with a CVT your impeller or prop speed would not be a issue ... just an idea.. either way love the channel!!

That was a great build man I never knew you could do it with the chainsaw engine real nice I think it was pretty good

Great vid man pls upload soon love the series 👍

hey I'm a fan can you make a paddle jet board using that mini chain saw engine it would freakin' awesome!! 😁

Congrats on the 10k

Should have stuck with the original clutch on the saw

the only thing you need is a bigger chainsaw engine and the aggressive prop you had on the first time and you'll get a lot of speed with a bigger chainsaw engine cause the engine u have isn't powerful enough for the aggressive prop you'll get like 20-30mph difference with a bigger chainsaw motor and the big aggressive prop an expansion chamber will also add more power and create a powerband effect cant wait to see updates

This guy, "I'll test my boat in my boat!"

100th of a metre hahahaha you funny bugga

its not deep enough for the prop. cant get enough water at high revs with slow speed, you need to ease into it like you said, or extend it more.

10 mill is 3/8s American

Where do you get those props in nz bro?

How did you make your boat

Hey, where can you get those My Little Pony DTIs? I can't find them on Bangood. Are HBs more, or less, accurate than 2H?

What are the uni joints you used for the adaption to the jet unit ? What are they called and where did you get them ? Cheers

What size turbine did you use last?

Mod the chainsaw motor port and polish the cylinder

Configure to jet setup please 😭

When did you build that tinny

You know this is headed to a long tail Ti racing boat.

Yup! It's deep AHAHA AHAHA

066 needed Lovn the videos Once you get a decent mini jet boat you should bring it down here to the South Island and join me up one of the amazing rivers we got I’ve got a tiny tuff jet

It's good idea . BUT I WORK WITH CHAINSAWS,THEY SOUND HELLASISH !!!!!! NOT ON MY DAY OFF

10mm = 3/8 inch in America. I know its not an exact match but its how we remember it

variable pitch prop

That motor is not design to run continuously! You will burn that motor up in no time .

that's not a noife
