I recently bought a Sea-Pro 22CC with a Yamaha 4-Stroke 225

Im wondering what the maximum operating range for this engine would be?
The manual I got says the Max RPM is 5000~6000 but that isnt really
that specific. Im thinking the max RPM is WOT RPM?
Does anyone know if this is a downscaled 250 and if it is a strong
engine that could mabe stand the stress of periodic bursts of speed?




Yamaha recommends propping the boat in the upper 1/2 of the motors operating
range, which for your motor is 5500-6000 rpm. With a full tank of fuel, a
normal load of people, and any gear, coolers, ice, etc. make sure the motor
runs at least 5500 rpm.

Your motor is built for long runs at high rpm if that is what you want to
do. Most boats cruise at around 4000 rpm.

The 250 is a completely different design than the 200-225 motors.
