Under load, the motor RPM increased, but the boat didn't accelerate. I figured a spun prop, and purchased a new one. Worked fine for a few trips. Now it did it again yesterday. Also, throttle will increase the RPM, but boat slowly comes up to speed. All the gauges read well, and engine sounds fine, other than the slow acceleration. Could I have spun a second prop already, or?
