    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...

    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.
