    I have a 15 foot Lyman that did the same thing with a 1957 Johnson 35hp. Wouldn’t ring up rpms well.

    Started thinking prop. Sure enough…It had at least a 14 pitch. Went to a 12 pitch. Sings like a bird.

    Gonna find out again tomorrow on a 80 mile river round trip. Picked up a few mph too.

    Well greg, i’d like to hear how it performed. I found a 10 3/8 x 12 1/2 (amc 382) and so i’ll give that one a try.

    Took apart the tank pick up unit and found the two zip ties were loose. Replaced them but the hose was still intact and seemed secure anyway. BUT, the gasket seemed to be very distorted, almost looked like it had melted. I have a nos one on the way thanks to ebay. We’ll see if the helps. ALSO, the gasket for the cap is missing. Not sure if that would be making a difference or not.

    As far as the connector issue goes, I’m quite sure it’s an OMC type and not a mercury one. Here are 4 I have in these pics for comparison. I’m using one like the two on the far left. Sorry for so many pictures. I just want you guys to see what I’m seeing so we can relate! 😀
