Hi Everybody. Mercruiser Alpha one. Just put the boat in the water and found a slow leakage in the transom plate area. The water accumulates in that little chamber where hydraulic hoses go in, and drips into the boat. First thought that it is leaking thru the hydraulic manifold gasket. Re-sealed that area properly, but still leaks. No metter engine runs or not. Any ideas, Y-pipe perhaps? Thanks in advance.
