A 12V compressor + drilled a hole through an old oil plug and hot glued an attachment point for the compressor to the oil plug. The pressure kept stable for more than a minute so we passed the Volvo Pressure test  ;D

"Connect the pressure gauge to the oil drain hole. Pump the pressure up to a level not exceeding 78 kPa (11.31 psi). Check that the pressure remains constant for 1 minute."

Interesting idea, but did the test pressure not vent via the dipstick (or filler cap)...?   Bill..

The oil filler cap and dip stick both have a rubber ring. Apparently completely sealing them.

The pressure test is mentioned in the Volvo Penta Workshop manual, it's not something we invented our self ;) The adaptor to fit an compressor to the oil drain plug is a DIY-fix.

One question for everyone, when you change the inner and outer semering of saildrive shaft, do you grease it with some grease, maybe with marine grease?

The screws that hold the saildrive housing, and the screws that hold the zinc anode, do you grease it? These screws are stainless steel and go into aluminum, maybe it would be good to grease them with anti-corrosion grease (Duralac) or grease to lock screws?

Grease on the seals/shaft,and loctite on the anode allen screws. Geoff
