I found a 12.5 hp vertical shaft engine, will this work or does it need to be horizontal?

i dont see why it wouldnt work. you'd just need to design everything sideways

and it wouldnt be as easy to design because i dont think anyone's used a vertical shaft before

actually ive thought about this before and i saw that you can get a sort of gearbox to convert vertical to horizontal and vise-versa i forget where tho Rolling Eyes

Not unless you want to hook a hydraulic pump and drive to it. I guess you could put a helical drive gear system in or use a 90 box but thay are expensive and probably wont hold up to the shock and torque from the rider.

One of these days someone has to build a vertical shaft winch I mean there has to be a way to do it with out doing some crazy @ss $hit to make it work surely

why would you need a 90 box?

you could just mount everything "sideways" so your axle is vertical also...

You can't just mount your tav under the engine and have a sideways spool and chain cuz the chain would probably come out of line and/or always fall off.

And you can't just turn your engine sideways, or it would f**K up cuz the oil wouldn't lubricate the components properly and you would have to remount your gas tank cuz that probably wouldn't feed properly either.

just keep your chain tight and use a centrifical clutch

Use a slipper plate setup found on most driven snowblowers. I'll look for a diagram later.
Basically it takes a plate on the vertical shaft that spins against another plate (TAV) plate. They're pretty durable- my friend used one on his go-kart cause we got a 25hp motor from a ride-on tractor. Hasn't shown any signs of wear yet.

Is there any way to keep tension on the rope even if there is nobody riding? Like have some type of fairlead that would create tension to the spool, even if the rest of the line is slack?

I'm not sure if that would even work but maybe? That might cause issues pulling the rope back out though unless it only works one way. Plus it would just make the whole thing too compicated, haha.

I think it can be done with some R&D.
