go devil motor

Why is it that a simple idea has to end up sooo complicated
Im sure thatthe uni joint could go and the shaft / casing bolt onto
the mounting holes on the engine. Fit a yoke similar to a rowlock to
mount/steer it . Probably try it on say 2 1/2 hp first -lighter!
howabout making a home made prop and fitting it to a whipper
snipper, one of those with the detatchable head. actually Ive got one
in the shed !!, back in a minute.
Another thought , battery drill , long shaft, prop , if its a 12 v
drill pull appart an old battery and use it as a plug to hook up to a
car battery/ solar panel!!. Im sure youd get slow but steady progress
with it. It would certainly be quieter than taking a little 2 stroke
onto the lake.
