Location: Elk River, Minnesota | When you do the sea foam, do it two ways...first, give it a deep cleaning by injecting it directly into the carb or injector throat while the motor is on high idle, until it dies. Put a bit more in and let it sit for 20 or so minutes, then dump the rest in the tank and go run the heck out of the motor. That will clean all the gunk out of the engine. Then, replace your plugs (cheap insurance). The fuel filter should be replaced ever other year or so so again a preventative maintenance issue there (another good thing to do as well since the motor is new to you).
I still think you are over pitched on the prop. I'll bet anything if you drop to a 19 pitch with same diameter, and raise that motor a hole or two you'll be sitting pretty. With two guys and gear, a 19 should help out. I'll bet if it is just you in the boat, you'll be really close to top end...add one extra guy and gear, and it can bring rpms down quicker than one might think.
