Hey I was fishing this weekend and my rpms sometimes would run about 5500 which is what i've been told is normal. At other times the rpms would get up around 6200 unless i backed off the throttle to about 3/4. Any help would be appreciated. My prop has some nicks and I need another one, but would that result in the rpms changing at different times.
