Not that I know of. I think it's a totally random thing. When it was discovered that one of our drive couplers was failing I'm guessing there were about 1,800 to 2,000 hours on the engines. But the drive coupler on the other engine was just fine, and in fact we've kept it and the Jabsco pump bolted to it as a spare raw water pump.

All I know is that in talking to Bob Smith about it he told me what I've already described earlier and said that eventually, every coupler will fail in this way. How long "eventually" is is anyone's guess.
