Sounds more like a weak stator or switch box to me. If it was the fuel pump, it eould normally take off abd then fall on its face as it sucks all the fuel out of the bowls. Have somebody pump thr primer bulb while it won't turn up, if it picks up rpm's then I would look at the pump. Those early pumps are nla, you would have to try and rebuild it, or go to a newer style pump. To me this sounds most like a high speed stator on its way out.

Low RPM and Speed
Thanks guys, after doing more research, it does sound like the stator. I will take her out again after I check the plugs and install a fuel pressure gauge and new fuel filter. Then pump the bulb as you suggest Ferm and see what the impact is, if any.
Stator was replaced in 2011, along with the switchbox by the previous owner. I thought that I had that part behind me...perhaps not.

Root Cause: Zebra Mussels
Yes, what I thought was a engine mechanical issue was the drag created by a couple thousand zebra mussels. No bottom paint on this boat since I intended on rack storage this year, but due to Covid, the rack storage building was full, and the marina fork lift had mechanical issues. So, I kept the Welly in a slip. I expected a power and acid wash at the end of the season, but I but not expect the mussels. I had her in Lake Huron last year – no mussels issue there. Anyway, I wanted to follow-up. Sorry for wasting your brain power on my screw-up.
