Can anyone tell me the difference between the motors on airboats and
the motors in airplanes?
I notice quite a few airboat engines at 1/4 of the price of airplane
engines. I figure if your going to tear down and rebuild anyway, why
spend the extra cash? So far the only difference I can tell is the
certification which brings the cost up.

The big question is, do they still have the dataplate?

They may -- or they may not -- there is no requirement for a dataplate
on an airboat engine!
