I have the OMC manual for my motor. I have been following it to the best of my ability.

Boat is new to me. First thing I noticed was cracked and warped carb bowls. Replaced the bowls and rebuilt the carbs with OMC parts. Transferred the high speed jets. They are #69s. Replaced the port and starboard fuel manifold spaghetti gaskets also. Set idle mixture screws to 5 turns out. Still the bogging up to plane and 4k rpm max.

Found the motor had the wrong spark plug wires and NGK plugs. I bought a used set of OMC coils and wires and changed the plugs to the champion QL78YC.
Installed a new OMC power pack and a New CDI stator.
Bought JugHead316s easy timer and I am at 6 and 20 respectively.
Throttle roller has been replaced with a machined peice.
advance and throttle have been set to open at the same time. Throttle cables have been adjusted per the OMC manual.

learned about the VST and found the cover to be warped. Tried sanding it down and replacing the gasket, float needle and seat. Made it leak worse. Bought a used fuel bracket with VST cover. Installed the float,needle and seat in the new bracket per the manual, level with the house and I checked float drop. Within spec.

replaced the diaphragm in the vapor pump.

Rebuilt the VRO fuel side. Replaced all the fuel lines and the recirculating lines. Some OMC lines, others from Napa. If they were form fitted, I went with OMC as to not create any pinches in the lines.

Checked/cleaned fuel filter on motor and replaced the o ring and gasket.

fuel tank does not have anti siphon, and I’ve tried 2 different fuel bulbs, I extended the fuel line to orient the bulb in the vertical position.

AFTER ALL THAT I am still having bogging all through the rpm range and 4-4200 max rpm. Although it has recently started to do a sort of lean sneeze but it’s not the lean sneeze it’s what I call the rich sneeze. When it sneezes, it’s like someone is flipping a switch that turns on the power and it jumps forward. Once it does that a few times, it magically opens up and I can trim up and reach 5k RPM max. I just want this dang motor to run like a top. I enjoy mechanics but this thing is driving me crazy. Please advise.
