Hi Jerry,
I am presently building an RV-4 (when I am in the country!!)
but I have also built a Team Minimax that is now ready for cover. I
have a Kawasaki
snowmobile engine (40 HP) for this airplane and I am using a
5-belt redrive that bolts the carrier for the prop sprocket to the
bottom (top?) of the
engine case. If the OMC mounts to a snowmobile like the 2
cycle engines (bottom of the engine case), then you will be able to
adapt one of these
drives to your needs. Unfortunately, I do not have any of my
airplane stuff here in Bangkok and I can't remember the name of the guy
you need to call.
You need to call the guy who is building the small replica
aircraft (Pitt's, Vagabond,Heath Parasol, etc.). Take a look in the
December issue of Kitplanes.
You can also call J-bird (advertises in Sport Aviation) but I
haven't been happy with their service. I have one of his redrives but
I'm not really happy with it and will someday replace it. A lot of
these are flying, but the propshaft is only 1" in dia. which is WAY to
small IMHO. This drive only costs about $500 and you get what you pay
for! Hope this helps.
