    Does my GL-5 75W90 need to be official?

    I’ve read that VP oil does better with water contamination and is better for shifting…

    Oil Pressure Sender failure modes?

    A pressure switch is very different than a pressure sensor/sender. A pressure sender has a strain gauge, piezo sensor, or some other means of measuring strain on a diaphragm to convert into an electrical resistance. A switch just opens or closes a set of contacts.

    SX-A Gear Oil Screw

    Mine is difficult to remove every year. Finally bought a hex socket version screw that I’ll install this fall.

    Compression test

    Also have all the spark plugs out when doing a compression test.

    Compression test

    A simple test is to squirt oil in the cylinders and repeat the compression test. If the pressure is higher, you have bad piston rings.

    Volvo/OMC Raw Water Pump Repair/Replacement

    I wouldn’t want the paint to flake off and get into my cooling system, like on fuel pumps. ;) My boat’s an OMC, so I’m good on natural brass, (bronze?).

    VP SX drive low oil but no sign of leak

    Keep adding oil. Make sure the drive is level. I can’t remember the value, but I think it’s more than 2.1L.

    Volvo/OMC Raw Water Pump Repair/Replacement

    Good point about the age and wear. Sadly, it doesn't appear that Johnson makes my style pump, shown below.

    Volvo/OMC Raw Water Pump Repair/Replacement

    My '95 OMC/Volvo raw water pump (3858847) is leaking a bit from the shaft seal. I can address via an aftermarket seal kit, aftermarket water pump, or an OE water pump. What's the team's consensus on the best way to address? Are the seal kits sufficient quality for a good repair?

    New Winch or Winch Strap?

    I don't think a 20V drill would have enough torque. You're a great candidate for an electric winch.

    Volvo Penta Trim Cylinder issue

    Yep. Blow air into the left cylinder lines and it should come out the right cylinder lines.

    Outdrive service

    By not coming out the upper hole you mean the overflow hole next to the shift mechanism? That's the correct place to check. If you're getting oil out your water intake, the water passage between the lower and upper half of the drive is corroded/failed. You'll need to separate the drive to...
