Makoman I know your not doing 34 miles an hour cruise with a 225 hp on that boat. If you are doing 34 miles an hour at 4700 rpms then like scott m said you need a different prop. That motor at wot should be between 5200 rpm - 5750rpm according to your manual. My boat is just a little unpowered I would prefer a 250 hp because then the motor doesnt have to work as hard and I would get more life out of it. I tried a few different props and now am running a 14 3/8 x 15 an getting 5400 rpms. But I took a measurement from the bottom of the boat to the sced on the motor and it looks like I can raise it another inch higher on the bracket, which would then increase my rpms between 200-300 rpms. Thanks scott m for your input.

There is something wrong with those numbers, I ran a 14 1x2 X 17 SS w/slight cup on 23WA and would trun 5400 trimmed out and close to 44 mph depending on the water. Try a different prop.

Gary was that with a 225 or 200 hp. And was that a 23 seacraft wa and what year was that, because when sea tracker took over the seacraft mold in may/1985 they made the boat a little lighter. But if those numbers were with a 200 hp 2 stroke Im willing to try another prop.Thanks Peter

Those numbers were with a 1989 200 Hp carbed Merc. It is a 1989 Seacraft 23WA. I still have the old aluminum prop laying on the shelf and nothing to use it on.
I just repowered with a Honda 225 and get about the same speed, also installed a fuel flow meter but have tried it out yet.

Gary was that motor on a bracket?What numbers were you getting at a cruise with the old mercury motor. Would you be willing to sell that aluminum prop or be willing to let me try it on my boat? I ll pay for shipping and handling. Also do you know the numbers on your 225 honda at cruise, and at wide open throttle. And what size prop are you using with the honda. Also what is the weight of that boat. Thanks for your input in advance. Peter

pmtautog,my WOT is 5500 rpm at about 42 mph.The numbers I posted was just what I was cruising at that day.I went from a 14.5x17 Vengence to a 15.75x15 Mirage plus and all my numbers improved but she is still a gas hog.
