Got her out on the water for the first time (project boat). Just replaced the ignition (all components except the stator), and put a used lower unit on it (original wouldn't shift)
Runs OK at idle, and when in neutral I can rev it up just fine. But when I put her in gear and throttle up it's like it'll only go at 1/4 to 1/3 throttle.
Runs nice and smooth, no missing or sputtering, just runs like the throttle is only partially engaged, even when it was held wide open.
I was thinking control box or cable, but it all works fine in neutral, I can't see what difference putting it in gear could make to the throttle control (it's electric shift).
I have replaced most of the ignition components including the timer base, so initially I was thinking maybe the timing advance, but it works fine in neutral.
Then I started to wonder if the new (used) lower unit I just installed might be binding internally or somehow not working correctly causing the slowdown, but I surmised that if this were the case, then I would hear something or feel something, and I didn't.
Then i started thinking carbs. I checked fuel filter, clean. Checked fuel pressure, but looks ok (disconnected fuel line coming out of pump, and turned it over a few times, seems good).
But as I was fiddling with the choke, and the idle adjustments it almost started going good a few times, but always fell back to limping along pretty quick. Sometimes I found that if I clicked the choke button on the control box and held it, it would almost start going good, but then it would bog down again. So I'm fairly certain these carbs need rebuilding.
Carbs and transmissons have always been my weak spot on cars and motorcycles, but these things look pretty simple.
What do you guys think? Any advice before I tear into the carbs? Am I missing something?
