I have some extra water coming in a bolts just behind the packing nut. I had a bot mechanic in our yacht club look at it thinking the packing nut needed adjusting, but he checked it and said the nut is good and checked the hose clamps on rubber hose attached to fiberglass tube and they were tight. he notice two bolt just behind that that were starting to rust and though it might be leaking there. He said he thought the strut bolts and aft another 18" or so and did not know what those two bolt were but suggested I replace them with new SS bolt next haul. They run horizontal running fore and aft next to shaft tube.
