@Veronicaš³ļøāā§ļø :inanna: There is a rubber gland where the propeller shaft goes through the hull. Itās lubricated by sea water, but needs a millilitre of grease inserting once a year to keep it watertight. This can only be done when the boat is dry docked.
The seal between the gland and the shaft is very narrow, so a plastic drinking straw, which can slip between the two, and then squeeze the grease in, is the ideal way to get it in. If you try with paper, the straw explodes from the pressure.
Iāve heard it can be done with a hypodermic needle too.
