| Hey guys, I recently purchased a used boat. It's a Sea Nymph FM161 with a BF50A Honda 4 stroke. The boat is 16.4' x 72" side console aluminum boat.
I took it out for a trial run. With just me in the boat it would hit 6,000rpm before full throttle was reached - maybe 3/4 or 7/8 of full throttle. According to the "Honda" tach in the boat (which I assume was installed along with the motor) redline is 6,000 rpm. Current prop is a "Scott" 11 1/4 x 13.
Normally I would think the thing to do is move up in pitch to bring down RPM. The problem is that the prop is damaged. The tips of all 3 blades are sheared off around 1/8" or 3/16" and all dinged up.
So my problem is I don't know if I put a new 13 pitch prop if that will bring the RPM down off redline, or should I get a 14 pitch prop and assume the prop damage is not effecting RPM very much? On a budget and only want to buy one prop.
Thanks guys.
Edit - Speedo showed around 30mph on the trial run.
