    Mercruiser 898 Cranks but Won't Start

    Hello, I have a 1982 Mercruiser 898. I was cruising around the lake for about 2 hours yesterday, no problems at all. I go to dock the boat at the end of the day, we get to the dock and as I am about to turn the key off and call it a day, the engine stalls. I figured it was nothing and tried to...

    Trim Sender Wiring

    Does anyone know where I can find the wiring diagram for a trim sender switch? The really old ones that go on the side of the drive, with the limit switch on the other side. Better yet, if it is simple, can someone just tell me how it hooks to the gauge positive, ground and whatnot? I can't...

    Holley 4 Barrel, Carb Secondaries Not Opening

    Hello, I did a 2 to 4 barrel swap over the winter and I just took my boat out to the lake today.
