    Mercarb 2bbl Plunger Spring - Lost Mine

    Bellows Job - Shift Cable - Alpha One

    Getting ready to do a bellows job on a Mercruiser Alpha One - and from what I've learned so far it looks like the shift cable is sacrificed to do the bellows on the shift cable. Is that correct? Thanks - Steve

    Rebuilding Mercarb 2 BBL - Check Ball?

    Hello Gents, I am rebuilding a mercarb 2 bbl - and the diagram shows a spring and check ball under the spring plunger that goes in that round pocket in the carb, but I don't believe these parts were in the carb when I took it apart. Would the carb work without the check ball and spring under...

    Hello Gents, I have an in-line 4 merc, a 1987 165 hp, that is running pretty poorly. I have installed new fuel filters, complete new ignition w/ wires, and have checked it all twice. It runs OK for a little, then starts back-firing, with squeaking sounds coming out of the flame arrestor...

    Mercruiser Flame Arrestor

    Good Day Gentlemen, What is the best way to clean a flame arrestor? Brake Cleaner and Air? Why no air filter - Fire hazard? I recently had to fabricate a new engine cover, made it out of wood, and realized that I have essentially blocked access for air flow to the flame arrestor. Does...

    3.7l 4 Cyl 165hp Temperature Switch

    Good Day Gentlemen, My next task is to debug the coolant temperature circuit. I was wondering if I should see some type of movement of the needle at all when I turn the key over, whether the boat is cool or hot? Will it move a hair to indicate power on? Seems dead. Is there an easy way...

    Merc 165 3.7l 4cyl Starting Issues

    Hello Guys - My boat is starting intermittently. A lot of times I clear the "Click" of the relay, but it's not turning over the engine. Then all of the sudden she'll turn over. Do you think this is the relay on the block, or do you think it's in the starter? Any easy tests to diagnose...

    165hp 3.7l Merc Fuel Pump Filter Latch

    Hello Gentlemen - I have a fuel pump with the filter on the bottom, that is held on by that metal band and screw set-up. I busted the metal band portion trying to unscrew the bolt - the whole things was rusted pretty good. Does anyone have a suggestion on where I can get just that metal...

    Merc 165 3.7l 4 Cyl Voltage Regulator

    Hello All - Going Through My Boat Connection By Connection, And Noticed That The Pervious Owner Didn't Take The Voltage Regulator Seriously, As There Are No Wires Running To It.
