    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

    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.

    Don't know how you would get a reading without actually seeing and testing the wiring. Might have just been rust allowing voltage to transfer, but would do nothing when current draw increased

    Temperature Fluctuates - 2015 350 mag mpi ec

    I think of the poppet valve as a pressure differential valve, it keeps the pressure to a set limit in the exhaust manifolds. It helps keep the mans with warm water instead of cold. Most of the cold water not used to keep the motor at temp goes straight out the exhaust via items 29 and 20. It...
