I have a mercruiser alpha one gen 2 sterndrive. I am getting water in the gear oil. I get water faster when cruising verse when doing more swimming. I have installed new gaskets. I have separated the lower from the gimbal housing. When I pressure check the stern drive, it holds pressure. When I pressure check from the reservoir to the gimbal housing, it also holds pressure. When I put the two back together and pressure check, it loses pressure in that connect for the stern drive to the gimbal housing.
