Fires up and runs perfectly on muffs and initially in water. Runs great and trolling speed and at high speed (on plane).
At moderate speed however, when the engine is working to get the boat on plane, it tends to pop/backfire which causes power loss.
backing off the throttle helps get it back to idle or smooth running.
I find if I give it more linear or quicker throttle, i don't have this issue.
I have gone through 3 fill ups with ethanol free gas and replaced the fuel filter/water separator. cap/rotor look good.
I've considered, plugs/cap/rotor/fuel pump/fuel regulator.
Any thoughts? buggin the heck out of me.
