I just got my new Key West 246BR bay boat, equipped with a Yamaha F300. This is an AMAZING combination!! I would like opinions on the correct prop however. I have tried three different Saltwater Series II props - 17, 19 and 21 pitch.
So far, I am most please with the 21-pitch. It still has good "hole shot," the best top end speed (58 mph loaded with three grown men), the best fuel economy, and by far the best cruise speed. It seems to be an easy choice.
However, it will only reach 5400-5500 rpms completely trimmed (I will also be installing a 6" Atlas Jack Plate). Is this an acceptable top-end RPM maximum. With it being a high-performance motor, I just want to make sure this won't do anything the harm the engine.
Thank you for your input.
