ur in a good range right there that is if ur prop aint worn out (what im sayin is that if ur propeller is newer(not to much wear) thats a good rpm cause as ur prop wears u will pick up rpm's!!!! and u will start floatin ur valves around 4500 so i think 4200 is safe!!!

You have a governor that protects you. 4200 in the water is fine- you have a strong motor.
