Just a thought. My Nic recently spent a month on the hard in the UK [Poole YC] & I forgot to check the cutless bearing seal on the prop, on relaunch. Seawater trickled in over a week before I realised it was not rain water in the bilges – taste test etc. So I drained the seawater and repressurised the prop shaft seal, using the unit under the cockpit floor. I assume it had dried out while on the hard. Oddly enuf it did not happen last year – colder maybe. Cest la vie.
If, as I understand, you are writing about the greaser pump in the after port side of the engine compartment, if my memory serves me right (I don’t have the book in front of me) the screw top pump pushes grease into the white metal shaft bearing.
I believe the instruction is to give the pump half a turn either before or after using the engine.
