I just looked over the web site and the available specs / drawings.  Only
two concerns I could see:  The bearings appear to be spherical ground roller
bearings.  That's good.  But the arrangement looks like it is set up with
the heavier bearing for thrust *toward* the engine/transmission.  That makes
sense for a marine application that is being pushed 99% of the time.  Not so
good for a tractor application (canard fliers take heart).  Perhaps the
bearing cartridges can be swapped.

The other concern is that the spacing between bearings looks short.  Again,
not an issue for a marine application that would have at least one drive
line steady bearing and minimal gyroscopic or other bending loads.  Not so
good for an aircraft application swinging anything other than a very light
prop.

It may be that both of these issues can handled by the stock reduction unit,
but make sure you scrutinize them carefully before you hang you life on it!
