I have a 100 HP Yamaha 4 stroke......problem........winter freezing weather has popped the water pump oil/water seals out of the water pump housing (cocked them) causing water to leak into the lower unit gear grease.
The dealer said all they've done is pushed em back and locktighted them back in. Have you had an experience, or heard of the problem up in good 'ol AK. I wonder if it is just a bad design for the 100's or if there is a new part, new seal, or different housing that might take care of it. Thanks, Digger
