Seafoam will help a bunch. What type of motor are you running?

Seafoam is good stuff. For my Etec they recommend if you do a lot of idling to run the boat WOT for a bit to clean out the injectors. Not sure if that would apply to a carbed engine.

When in doubt, set the hook.

I drive slow a lot scanning but then I drive WOT too. Ive pulled my plugs and looked at them to see how they look and they never show signs of burning bad or foul out.

Proper propeller and Seafoam will sure help.

Make sure your running proper RPMs at WOT. And some additive of your choice.

I'm in a similar position as you are. I'm over propped pretty significantly and hoping that's my only problem. With just myself and a mornings worth of gear I can do about 4800 rpm on glass water, and my engine should be somewhere in the 5600 range I believe WOT.

I'm just making sure to use the mercury fuel additives as I go out for the time being before I can get my hands on a new correct prop. My thoughts are this is better than doing nothing about it.

(Mercury Quickcare as a sort of "fuel stabilizer" and Quickleen as the fuel system cleaner)

I have also shot sea foam into the carbs one afternoon and let it smoke out my driveway after about 15 minutes. Not sure if it's a placebo effect but I believe my engine at least sounds better now!
