I have a 2013 4 stroke 9.8 Tohatsu on a 14' jon boat. Motor came with a 7.5 pitch prop which does great with just me and my son in the boat. Turning 6000 RPM's. Problem is when I load the family, gear, and 100 pound Lab I drop down to 5300 RPM's and about half the top end speed. My question is if I go to a 6 pitch prop should it help top end and make motor run better. I have a tach so I can make sure not to exceed 6000 RPM's when I have a light load. I realize its just a 9.8 and no speed demon. I bought it because we like to camp and the lakes at state parks here require a 10hp or less. I would just like to get as much as I can out of it without damaging the motor. Thanks and great site by the way.
