I have a Four WInns 17.5' 4.3L SX 1996. I recently took the boat for a

spin around the lake in anticipation of spring. When I got back I
noticed white foamy liquid coming out of a slot in the side of the
stern drive. Upon further review, gear oil has water in it.... My
question is...is this a common problem with Volvo Penta Stern drives?
How difficult is it to repair. It looks like six bolts and removal of
the hydraulic cylinders, but I don't know what's inside. I have
ordered a manual. This is the first time problem with the boat.
