ok so took boat out this morning, two things happened , ran like a top sitting there no overheating oil pressure good started going and it wouldn't get on plane and bogged down after a few minutes trying to get on plane and stalled like too much fuel, then I get back to dock and all the sudden I'm not getting any fuel
, tossed back on trailer and took back to house pulled that fuel pump and the arm looked like it had 80 thousand miles on it, so I installed another fuel pump and nothing, now I wonder if the anti siphon valve is bad , wiped cam lobe for fuel pump or what.
either way I think I'm going to a electric fuel pump then ill recheck timing and give it another go .
would there be a big difference in jets between a 120 hp and a 140 hp mercruiser carb? researching that I reckon.
