Full throttle in gear I get about 20% power (if that) and can only get to about 3600 rpms.

So far I have rebuilt the diaphragms in the fuel pump, blown out the fuel filter, changed all of the hoses internally for fuel on the engine changed out spark plugs and have good compression 100+ in all three cylinders. I checked the gas tank and have ethanol parts from the hoses in the tank and have now bypassed my main fuel tank and tried running of a small portable tank with clean fuel.

went to the river after all of that...no change.

Tonight, ran motor with clean gas and carb cleaner and sprayed out carbs with cleaner but have not been back to test under load yet.

I am a little leery of rebuilding the carbs since I dont consider myself much of a mechanic, but does any one else have any suggestions?


Sorry if this is not correct forum for this post.



Thanks for any help gang.
Years ago, I had the EXACT boat, EXACT motor.......EXACT YEAR.............and the EXACT problem.

I ended up having to rebuild carbs. I'm not good at that......I wish I was, because it cost me 700 bucks to have it done, but afterwards, the boat ran like a top.

While I was good about winterizing it, I really didn't know about pulling the fuel line and running the carbs dry, or fogging the motor. BOTH of those issues is what gummed up and damaged the carbs.

I hope this helps.

Later,
