Hi Floyd.

Since they changed the forum software last week, many of us can't log on or post. I can only get on occasionally. please be patient.

I would not go to a higher pitch prop, it will make it worse.

You've checked compression and spark, how about fuel delivery to the cylinders?

Do all the plugs look the same?
What do they look like?
Make sure all cylinders are getting fuel.

I would get a can of Seafoam in the gas, and a can or 2 of Seafoam Deep Creep for the cylinders and carbs. Use it to thoroughly decarbon the motor.

Also, check and clean the fuel recirculation system screens.

ok now i think i fund the probleme when i put my hand on the lower carb. i block half of the carb. engine go at 45mhp thats what i think a good speed for this boat so thats mean i need to clean the carb. and what is the adjustement for that carb. 1 1/4 turn its ok...??? what do you think ??

sorry for my english, i'm practiced now :/

1 1/4 turn is good.

Update the post with results, or if you have more questions.

Good Luck.
