From BoatUS Trailering
 

BoatUS marine insurance case files show that 44% of sterndrive boats
that sunk at the dock had a leak in the bellows.

Worse, leaking bellows were the cause of 20% of sinkings when the boat
was underway.

Most manufacturers urge bellows replacement every five to six years.

If you have muskrats around, be careful!

All decisions, even those made by liberals, are the result of binary thinking.

Muskrats and beavers sunk more than one boat over at East Fork Lake in
Richland Co. IL. especially in the days of the old OMC stringer
drives. They'd chew a hole in the big rubber gasket on the outdrive.
