    5.7l mercruiser gen 1 alpha 1 to vortec head swap problem please help...

    I didn't think the pistons changed between the vortec and non. Actually, I know that's the case. At least the vortec truck pistons were the same as the merc non vortec... Also skeptical that these engines care what octane fuel you're running under most conditions. 9.4 isn't exactly supercar...

    ignition switch source for fuel pump relay kit?

    Relay shouldn't overheat, its function in life is to take the strain off the rest of your wiring 😁

    Sticky Carb

    You need to adjust your cable. It should be long enough to push the butterfly valve closed slightly when idling

    ignition switch source for fuel pump relay kit?

    High oil pressure smell of gas in oil

    It might run for a few seconds after engine is off. Otherwise it's wired wrong (as in safety issue, needs to be corrected)

    Gimbal Bearing Noise?

    Yeah there's a gap. Should do the job though. I never replaced my lower, not sure what the point of replacing is.

    Turning it by hand shouldn't do much

    Mercruiser 3.0 squeal keeping engine from starting

    If you're sure the alt isn't the problem, you can reconnect the belt and turn the alt bolt. I usually get a crowbar and wedge it between the heads of the balancer bolts. Shouldn't take much to turn the engine with no drive, plugs, or accessories connected. My ears aren't that precise, but I...

    Boat lift options?

    OK, getting a little closer. Got the pilings driven, waiting on the lift (I'm told it will ship this week...) I've decided to do 2 separate systems, each with its own battery and control. I want to minimize the amperage through the switches and batteries. I'm going to decide on the solar...

    Mercruiser 3.0: Dead cylinder? very sluggish!

    Sounds like you've got a dead #1 cylinder. I'd start by throwing a timing light on #1, and/or a spark plug tester

    4.3 Vortec Upgrade

    The tube is longer than the dipstick. You're just cutting the bottom part of the tube off
