Yeah im keeping my eyes out. Ive also bounced around the idea of going brushless, but its just as expensive it looks like if not more. How about a .65-.7 airplane engine? The cowling on the miller is open, and I can fabricate water cooling for the head if necessary. The OS i looked at quick makes 2.2 BHP at 15,600 RPM, I just dont know if theres enough there to get a hydro this size moving.
Thanks again for the replies.
There won't be enough power for that hull using an airplane engine. The only airplane engines that would work would be converted ducted-fan engines. You could also use a .81 marine engine like the O.S. or K&B. Who knows, you may find that size first on e-bay.
