    Upper Crankshaft bearing below seal damaged

    Finally got a day with low wind. Took it out for a test run. Broke the dash pot and Idle wire last trip, but she still runs good and fast. We hit 24 mph at WOT on our night trip just recently.

    Awesome, love iboats for this reason, I appreciate the advise. I did hit it with a ir thermometer and highest temp reading was 155, we will be doing an impeller and thermostat on it as soon as they get here. The powerhead does not wobble much at all. This poor motor was neglected and is back...

    So pulled the flywheel just to check cause that's what I did to my 20 hp mariner recently, key is good and everything looks great in that area. So I went back through the work I did, I think I had a part in the fuel pump flipped. 😳. Found some junk in the exhaust hole, got that out. Was able to...

    Got spark for sure, I am growing a suspicion that the float got stuck in the up position blocking the fuel, I am gonna take it apart again and check.

    Good to know, thank you for that. We used a quick spray and that was it. I am going to get new plugs and test that. Only did the spark test by eye ball.

    So new motor project, trying to resurrect it. Not much information on the motor besides the guy before ran it out about 30 minutes and it died and that was it. He supposedly did a carb rebuild and other things on it, but when I got it, when pumping primer bulb gas was spilling from front of...

    20 hp Mariner No spark

    This is what it sounds like after all the timing adjustments and other adjustments in the post above with the timing procedure. Very simple. Going to take it to the lake tomorrow and do the full throttle timing. Does this thing just run rough like this? Should it be smoother? Timing is on spot...

    20 hp Mariner No spark

    Ok that works, another question I have, the spark plug wires on the motor currently are a 7 inch and a 9 inch wires, I ordered a new 7 inch one as that one was shocking me and needed replacement, on marineengine.com they have only the 9 inch listed, should I do 2 9 inch plug wires or just go...
