    MerCruiser 120 1968 2.5 not idling tight

    Thanks, I cleaned the fuel tank first thing when I got the boat. The boat did not have a fuel filter so a few weeks ago I put a fuel water separator on it. I pulled the fuel pump out an cleaned it and now it’s running good again. Hope it stay running good! Thanks for the tips!

    MerCruiser 120 1968 2.5 not idling tight

    Hey All, I have this 1968 I’m restoring and got and issue with a rough idle and when I give it a little it stalls. I’ve changed the plugs, coil condenser, points and rebuilt the carb.

    1968 MerCruiser 120 starts but won’t run

    Wow, spell check in the wrong, it’s I don’t have a fuel pressure gauge and it has plenty of fuel. It runs now after putting a USCG hose and a spin filter on. Seems to have a small Drip of gas around the linkage somewhere. I tightened the screws on the carb and I’ll check in the morning to see if...

    1968 MerCruiser 120 sterndrive water pump

    Okay thanks I’d like be be able monitor the water exiting. I see videos where there is a lot of water, when I let the engine warm up the temp gauge reads low end of the green. Is that a good indicator or do I need to see a lot of water? I’ll keep looking for the exit ports.

    Maybe I’m not letting the engine get hot enough for there to be a good flow of water exiting the ports?

    I removed the hose going to the thermostat and looks like plenty of water coming out when started. Where are the relief ports or where should the water be exiting the transom?

    This is an old out drive I thought water flows out the rear top end of the out drive and exhaust out the propeller?
