    '95-ish Glastron SSV195 carbureted mercruiser 4.3 starter solonoid wiring color codes

    The oil pressure switch is probably bypassed. Power likely comes off the purple ignition wire somewhere, maybe coil positive or choke. Follow the positive back from the pump to see where it goes.

    Alpha one gen one Y plate is it adjustable?

    It isn't really adjustable, but a corroded/sticky pivot bolt can keep the plate from moving freely. The return spring can also have the wrong tension, which may make the plate harder/easier to move in one or both directions

    Always feel like I'm taking crazy pills when I say this, but the plugs on my 2001 were brass, or at least non ferrous gold metal of some sort. The HG was also composite ...

    Winterizing 3.7l mcm 224 165 hp mercruiser

    Easiest motor ever to winterize. Step 1: unscrew the aft plug on the heat exchanger. Step 2: laugh at the rest of us and drink a beer. (Assuming no power steering) That will keep everything from freezing. The rest is normal maintenance common to all the mercs, I do everything between winter...

    You have a generator or did you spend all your money on the whiskey?

    Ugh. My mom "evacuated" about 1 mile in in Nokomis. Didn't listen to me to GTFO. Going to be about the worst place for the surge. Helene wiped out all the dunes already.

    Upper and Lower Drain Plug Merc Sterndrive Alpha 1 Gen 1 Question

    As @Scott06 said, check for a stuck gasket. I'd guess that without that gasket you'd get much more than a bit of water in the oil

    Gimbal bearing puller

    Iirc I used a bearing puller with the bell housing still attached. I do know last time around the engine was out and I knocked it out from the inside. That made for an easy job.

    2006 Monterey Boat with a 4.3L Mercruiser TKS Engine S/N 0w354897 Mysterious Loss of Power

    Revving with no load tells you nothing. If there's water in the tank it's initially layered at the bottom and not necessarily picked up. As the boat bounces it gets emulsified in the gas and then sucked up. You stop and it separates out again. How does it get in? You're surrounded by water with...
