    Low voltage to accessories from ignition switch

    Your checking it correctly, just saying if the ground or the hot going to the 10 pin connector is corroded, it would skew the reading. If you can connect to the battery neg for ground, you could determine it its on the ground side

    engine replacement ?

    The flywheel will be the same. After 1985 the flywheel changed to current one The one piece rear main seal started in 1986, but note marine is usually behind with motors. Check the block serial number to verify https://www.mortec.com/

    Low voltage to accessories from ignition switch

    That's quite a bit of drop thru a switch IF that is whats happening. All the boat gauges can be off. Might be on the ground side, even at the engine connector That said, you can replace the switch with any 3 position switch

    Riser Extension Blocks - Full Closed Cooling ???

    1989 Mercruiser 5.0/alpha water leaking from timing cover.

    Howdy Nate I sure hope its not from the back of the timing cover, because this would mean you oil pan is full of water My thought is the circulating water pump is leaking and its running down the back of it. Could also be anything else above it like, thermostat housing or other Pull your...

    Ignition wiring questions.
