Outboard boat motor??? - Page 2

heres a good use for a vertical shaft engine....

I built both craft with 4 stroke engines from riding mowers (from plans). if you don't mind the noise of a 2 stroke then more power & lighter weight are always a good thing.

Don't they get their cooling by taking in fresh water and exhausting it. another hurdle to get around.

A closed cooling system wouldn't be that hard to imagine but the water pump on an outboard motor might be an issue. Transmission would be easy if you had room for a jack shaft - just use one from a snowmobile.

Finally! you could power from the front, where high performance cars have been taking advantage of the front weight bias provided by their engine placement! Drive and Steer Where the Weight is!
The outboard motor control replaces the right handgrip, and you can even maintain REVERSE GEAR!

Think of the convenience of underseat storage, a blast of warm air straight to your faceshield in all weather conditions, and the ability to instantly smell diagnose any problems that may arise!

I'm imagining what your describing, I'm picturing some sort of funky fwd bmw lol.

looking at building a xr powered bobber for my daughter, and a snowmobile powered one for myself. The biggest downside I can see to using an engine designed for marine applications would be the cooling, I think. The cooling system on most of them is basically water as far as I know- and the engine is most likely designed to maintain operating temperature with a constant supply of 60-80 degree water. recirculating 160-180 degree coolant may cause some heat issues. I would love to have something ridiculous on a bike though- 200hp v6 hooked to a harley right side drive trans (should alleviate any offset issues) in a lightweight bike sounds like one sexy little suicide machine to me...

daves custom boats in san diego ran an outboard in a sandcar and was making serious power along with no weight it moved right along........

Shaft angle shouldn't be too big of an issue - after all, outboards all tilt when trimmed, and can be run with the engine trimmed all the way up, even the 4 strokes, so long as its got water.

I don't think any of the mfg are making the engine so if you trim up too far it loses its oil.
