I bought a project boat. (and have learned the meaning of BOAT) Break out another thousand x4.
82 Renken. 165 Mercruiser. Circa 1982
I had a local shop rebuild to the tune of 3500 the outdrive. Everything was resealed and a new gimbal bearing. Also had to have the floor repaired where the IL 6 bolts to the floor. When I bought it (for almost nada) the drive needed work. As we got into it the costs went higher and higher.
OK--that aside.
My boy and I put it in the water yesterday and we have a pretty good leak at the transom. The boy put his hands alongside the bottom of the engine towards the rear of the inner transom. He could feel two nickel/quarter sized machine holes side by side where the water was coming in.. We only had it partially in the water still on the trailer. The bilge could barely keep up. The holes are at the base of the inner plate against the transom (inner).
So, I have two over-the-counter shop manuals. In reviewing, and reviewing GOOGLE Searches, on "TRANSOM LEAKS" I am drawing a blank. I know the shop here in Fresno, Cal was pricey but alleged to be good. They are the Mercruiser dealer. I am leaning towards several possibilities which I would have to farm out to another shop. Recommendations from locals are directing me to a guy who I am going to talk to.
Where could the water be coming in at? That gimbel bearing housing base at the outer transom? Those two bolt with a rubber plug over the heads there at the bottom of the housing? Surely there must be a seal down there. I am going to talk to the re builder this morning but they are $$$$. So if the back of the boat has to come apart I will go elsewhere.
Looking inside the outdrive I can see new hoses, clamps, but I cannot physically get behind the motor YET--today I may need to climb back in there with a light to look at the back of the motor. I hope the bellows is not full of water, but the boat never went fully into the water, just enough to find where we had a leak. Which was about 4-5" up from the base of the gimble housing.
I am learning. Yeah I bought a money pit but it will serve my purposes once it it running.
