The water pump resides above the gear case, and is seperated from it by a seal surrounding the drive shaft. When the seal fails, the pump pressurises the case, and forces the lube out. That’s why we drain and lube our cases before we store them for the winter. Lots of fine outboards have been disposed of in our state, Wisconsin, merely because the gear case cracked from water intrusion.. Too bad. R.T.
