I took my boat down to Tampa and it is the gearcase. Just really really bites cause this thing is only one year old. After two weeks of having it I sent it back to the guy cause it was leaking all over my garage. I pulled the plug and found milk colored water and metal chuncks coming out. He says there was sand around the seals causing water to come in. He fixed it and all was to be fine... Guess not!![]()
