I have always wondered why, at some subliminal level, when you tip back a modern outboard motor, a little bit of the lower unit always remains in the water. Maybe the reason for this is to insure that one of the most vulnerable portions of the motor stays in contact with the salt water to insure galvanic corrosion will occur, and hence new parts will be needed. Or maybe there are unknown mechanical reasons why the motor can't be lifted that last six inches or so to clear the water. I mean we went to the moon didn't we? So I was most surprised when I encountered two boats next to each other, one with this nifty little box under the lower units, and one without the little box.
