I have a 1991 225 Sea Ray Bow Rider. I believe my boat weighs in at 3900lbs before gear and yours is around 3500lbs. I have same engine and a Alpha One drive.
I have had the boat up to 48 MPH(on the speedometer) at the beginning of the year. Your WOT should be 4600 RPM. I do not know the best cruise speed for your boat. I think mine is around 3100 RPM and or 32MPH.

Thank you for replieing, but I was asking about the performance of a 260 CC with 7.4.
I have a 1989 260 CC w/7.4. I am currently running a 19 pitch prop and can turn 4000 rpm wot. That will produce a solid 39 mph. Going to do a fresh tune up this year and see if it will improve my performance. Motor says it will turn 4200 to 4600 rpms. Wondering if I need to re-prop or just clean all the build up out.

I have the same boat and actually with the factory prop it only specs out from sea ray 35mph. I have gotten 37mph top speed in mine and 2 mpg is the best I could squeeze for Econ and that was with 4 people and 50+ gallons of fuel and gear.
Thank you for your reply. With that info, I think I will save the prop money for gas and cooler. It's about enjoying time, no reason to rush it. As far as a family boat, I couldn't ask for anything better!
