I am running a 454 Mag in my 240 sport with a Bravo One drive. I want to say its a 1.50 to 1 ratio on the drive. (I swear I read that on it somewhere) The prop I am using is a 23pitch Mirage. I also have a 23p Clever prop too. What RPM range should I reach at WOT?
I seem to remember hitting around the 5 K mark when I first got the boat. Now it seams like it hits closer to 4800. Could I have lost RPMs somewhere? The only thing I've done on the motor is to rebuild the raw water pump internals after the original impeller siezed up and toasted the belts. I did have the Gimbal bearings replaced too. Also, The flame arrestor was pretty dirty at the end of the season. Cleaned that completely when I winterized it. So no idea what effect that will have as of now. Thanks for any input.
