Trouble you can get is with what isn't known, I heard of one many moons ago imported from US pre La La days and when the engine eventually went after several years for overhaul it had for airboat use only cast inside one of the crankcase halves. No one knew, even the engineer and nothing in the books to say it had ever been replaced.
