Re: 23hp vanguard engine orientation

I don't know what beezer is talking about. The shaft would not move in either case. The reason for the note in the plan is that the 23hp engine would require a larger driver pulley, and that would interfer with the mounts as drawn. You can build the frame using 3/16" angle instead of the short ...

Whichever engine you choose I can calculated pulleys to suit. I need hp and rpm. The motor should not be run faster than about 4500 to maintain lift and thrust balance.
