    Mercruiser 305 V8 running hot at low RPM fine at Speed

    That looks like low flow to me at idle, and just a mess above idle. You want something like 20 gpm, probably a bit less at idle and on muffs. Edit: Scott beat me to it, what he said.

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    That's what the clear hose I mentioned is for. Bubbles if you're sucking air from anywhere.

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    I meant to say check balls *easy* to check. I think it would be difficult to overtighten, you want them closed at idle, they prevent the cooling water from going straight out the elbows.

    Upgrade from small swim platform to large?

    Looks like a nice upgrade. If the transoms rotted you'll figure it out soon enough when you start trying to attach things. As mentioned the real key is to make sure you have access to the transom inside--you'll need to bolt all the way through. My transom doesn't extend the full width of the...

    Fix gel coat or use keel guard

    The shipping of the resin is the killer. IIRC there is no discount when you order multiple gallons so might as well order them as you go unless you're in a hurry

    Mercruiser 305 V8 running hot at low RPM fine at Speed

    I...I just can't. But yes, loose balls are ready to check. How do you drain the cooler to winterize? Assuming it overheats on muffs? If so putting a hose into the t stat intake will isolate the problem to one side of the hose. If it's on the supply side of the drive, check for both flow and...

    Lost gearage?

    Yeah, your sister drives are useless unfortunately. Some 5.0 came with 1.65, didn't know the 5.7 did though. Agree with Scotts comment about the transom... I'd make extra sure it's sound before continuing

    3.0 Mercruiser seems to hang or seize when starting

    How much oil? Change it and run it. If it comes back might be new block time Good first step

    Lost gearage?

    That second drive comes up as a 1.84 mc-1. Probably won't work but *may* be able to prop around it. What pitch prop do you have on there now?

    Started, died and wont restart

    May or May not get away with just pumping the bottom. Crap and water will be there. But the leftover fuel may be sub par. How much fuel is in the tank? Full 100 gallons? When my boat was submerged I managed to get away with doing that, and I frequently get rid of water on the bottom in Jerry cans.

    3.0 Mercruiser seems to hang or seize when starting

    Almost everything in the drive turns even in neutral.

    3.0 Mercruiser seems to hang or seize when starting

    It shouldn't Yes. As others have said, pull the drive and the plugs and see if it will turn over by hand then.

    Motor won’t turn over

    I'm waiting for @Rick Stephens to start questioning the carb rebuild 😄

    Motor won’t turn over

    Still sounds like he's trying to idle with no throttle on a cold engine

    97 Mercruiser 3.0LX will run/won't run

    Disconnect the switch for testing. Still haven't verified spark loss, right? If it doesn't restart when disconnected, that isn't your problem.

    Motor won’t turn over

    Are you cutting back the throttle when it dies? You need to keep it 1000-1500 rpm until it warms up.

    97 Mercruiser 3.0LX will run/won't run

    If you're losing spark intermittently then there's a good chance you've got some faulty wiring in the ignition system somewhere. Loose connection, chafed wire, intermittent short to ground, etc. You'll have to confirm loss of spark first

    Maybe my turn for new boat time

    Nah, that could never cause a problem, right @tpenfield ? When do you splash?

    Won’t idle 3.0 Mercruiser

    Warped head, block... Guessing that a HG alone wouldn't cause all 4 to lose compression unless it was really buggered
