    Carb or worse?

    I’ve done some more “learning” today. I cleaned up the head pretty well. Not all uniform color but definitely as smooth as I was going to get it. Flat bar and feeler gauges told me there were several spots that .009 would try to slide through. Put head aside to contemplate sending to machine...

    Timing hasn’t been touched, to my knowledge, but who knows. Checking it may not be a bad idea.

    Carb or worse?

    I kept pushrods (and head bolts) in order so they go back in same location they came out of. I found a video this afternoon about adjusting valve lash, was very similar to what you said. It also gave an order of which valves to do at TDC and which I should do after 1 revolution of motor, after...

    Carb or worse?

    Ok, thanks. I will confirm block and head flat and within the .008 spec., confirm exhaust flapper in and working and check valves and make sure they’re seating (flipping head and pour fuel on them and check for leaking?) as well as confirm 4th cyl valves moving freely and not stuck/bent. If...

    Carb or worse?

    Alright, here’s where I lose total respect but I have to ask. It’ll be several weeks before I can get head done, summer is short and Father’s Day fishing trip this weekend. IF head and block found to be good this evening, can I reassemble and use motor if it runs? Am I risking more than just...

    So after another night of continual learning, I have more news. I tested compression with a more professional tester. Cyl 1 165, 2 and 3 were about 15 and 4 was 155. Between 2 and 3 was where manifold gasket was blown out, if important. Pulled head of (1st time so go easy!) and everything...

    Carb or worse?

    Another stupid question but I have to ask: would a failed exhaust manifold gasket lead to these symptoms of no power or acceleration and louder than normal operation? Could this have been the cause of my woes? That would obviously be assuming I’m NOT getting an accurate compression test but...

    If I can stop sobbing enough, I need to get a real compression tester that screws into the spark plug holes instead of trying to hold on the hole at correct angle. In a perfect world, 150 +/- 5 across all 4, correct?

    I removed the exhaust manifold and riser tonight, both looked to be in excellent shape. Gasket from manifold to riser was excellent as well but the exhaust manifold gasket was completely missing between cylinders 2 and 3. I attempted to get a compression reading on #2 because enough stuff out...

    Mine shouldn’t be a salt water boat but can’t say for 100%. All history I know is upstate NY but was owned briefly by someone before my acquaintance. I definitely do not own a machine shop, how cool would that be! I could sit around all day with no fingers staring at cool tools! 🤪

    Carb or worse?

    From my limited research, I’m guessing something like that. What I seem to read is that people head down a slippery slope of fixing it to have another issue, fix that and then another issue. Doom and gloom. I haven’t read much though, so not positive. I appreciate everyone’s assistance and...

    Carb or worse?

    Armchair QB time, should I be thinking motor is no good or is it worth trying to rebuild? I know every situation different, just trying to pick brain with experience. Catastrophic or (🤞) somewhat easy, swap some stuff?

    Carb or worse?

    I tried to post it to YouTube to be able to share it. Unfortunately, I’m better with motors than computers, so we’re probably screwed. If someone can tell me how to do it better I’m happy to try!

    Carb or worse?

    It has a manual pump, carter but I forgot the number. NEW INFO: this afternoon, I tried to check the compression. I got 165 in cyl 1 and a face full of what I believe was dirty water from cyl 4. Again, not a boat mechanic but I can’t see any situation where water in a cylinder is good. I...

    Carb or worse?

    Im sorry, motor is a 3.0. I don’t have any numbers on it. Just seems like too much noise to only be a fuel issue but I have little boat motor experience.

    Carb or worse?

    I’m guessing the tank was 3/4 full of old fuel he claimed was treated. He had some seafoam laying around so we added a bottle of it and I filled tank with 91 ethanol free. Hoping we were good. Apparently not. I’d like to drain tank and see if sludge in bottom and/or possibly a pickup filter.

    Carb or worse?

    I bought a 1998 Sea Ray 180 the other day, knowing it has sat 3-4 years. The previous owner is an acquaintance and respected in community but I had never dealt with him directly. Just prior to sitting, dealer had done pretty major service on it after testing compression, which was good (not...
