    Loud squeal and no idle. Replaced head gasket, put engine back together now this…. :(

    Turns out it was a vacuum leak. I forgot to scrape off the old bits of gasket on the bottom of the carb 🤦‍♂️. Runs awesome now. Time to get it in the water this weekend

    No unfortunately. Took the belt off and it still made the noise

    Loud squeal and no idle. Replaced head gasket, put engine back together now this…. :(

    Great question: I dont think it is. I took the carb off the manifold when I did the head gasket. I put a new gasket under carb but I don’t think it’s seated right. Could the leak be coming from the base plate of the carb?

    Im an amateur! Nothing can insult me. I did adjust the valves as per the manual. I have no checked timing as I don’t have a timing light but may need to get one.

    Loud squeal and no idle. Replaced head gasket, put engine back together now this…. :(

    I replaced the head gasket. Put it all together and started it up and it’s whining and squealing. What’s the issue? Also, the carb won’t idle, I assume it’s got something blocking the jets or some kind of issue. So far this boat has been a huge hassle! Any help would be appreciated. See...

    So I took the manifold off. Looks like the head gasket. Can anyone confirm?

    It didn’t overheat and I pulled the plugs and they all look the same. No water in the oil (as far as I can tell from the dipstick). I’m going to do a compression check to rule out the head gasket. I may end up changing plugs while I have them out anyways.

    Ticking/clicking noise Mercruiser alpha one 2002

    This noise showed up last weekend and at first I thought it was the belt as it sounds like it’s coming from that area or the starboard side. See video attached. What is it? Am I screwed?
