OK, so, yes, I was revving it in neutral!
I didn't think I was giving it a whole lot of throttle, but I won't do that again. Learned something.
I hope it wasn't 'cause I got it hot, but I'm going back to the basics which will mean a compression test.
First thing I'll do though is go through and check linkage and synchronization.
Sounds like this is probably not about a leaking gasket, but I'll visually recheck for leaks.
What I did NOT do was use the special tool to line up the high speed nozzles when replacing the orings. I'll buy the tool and put new orings in.
I did fully disassemble the carb, and let it sit in a pinesol / water solution for three days, in a warm environment. Got it really clean, but made no difference. Bought the jet tool; replaced the high speed jets w/ correct NOS parts.
I went through the ignition again after the third failed lake test, and it seems to be right on. I'll put that on the re-check list tho.
I ran it with the hood on, but part of the time with the front door flap hanging open; shouldn't have been air-starved, right? Seemed to make no difference.
Old boat was a 16' aluminum, 450 lbs; this one is a 19' aluminum, 950 lbs. Heavier, but not so very heavy. Modified V-hull that goes about flat, so it shouldn't be all that hard to plane, should it?
The prop is well below the hull; I don't think it's a drag issue.
I tried three tilt settings. They make a lot of props for it; I tried the biggest one, and the smallest one, with almost no difference. I don't know anything, but it feels more like a motor issue than a hull issue. When I back off, I get a brief power surge that I wouldn't expect from drag.
I very much appreciate all the help!
