87 omc 3.0. i have had a problem with this since last season. i replaced the prop shaft seal, water pump shaft seal & others in the upper & lower gear case. last fall when winterizing i changed the gear oil & fogged the engine. when i checked the gear oil after i fogged the engine it was full of water. the engine only ran long enough to fog the engine. any body with any advice on what to do next. i hate like he** to have to tear down this drive again, & frankly i'm stumped. how is water getting to the gear lube when i'm only running the engine off the muffs? also last yr. when i had the boat in the water i could see the gear oil rise to the surface. so i figured it was the prop shaft seal.
