Seems to me that if it runs well on the hose but not in the water, you may have carburator problems a d may need to rebuild them. Cliff 1966 13' Sport with a 1993 40hp Yamaha 2 Smoker

The boat is a 1995 13 and the motor is a 2000 Suzuki 25 hp four stroke. So I took the boat to a Suzuki dealer and they told me that somehow water got through my water fuel separator and got into the carbs. So they cleaned the carbs and it still didn't have all the power it should. Next step was to check out the prop. It appeared that the prop was smaller then it should have been. I guess after having it refinished 3 times it shrunk a bit. So I ordered a new Michigan Wheel Vortex xhs 3 blade 10.5"x11" and a hub kit and plopped it on. Now all my problems are solved!

Try a 9 or 11 inch pitch. The cavitation plate should be running on the water surface when you are on plane. Rich

Has this motor been run on this boat in the past. Is it possible you have a long shaft motor on a short shaft boat and running way to much pitch, and carrying a heavy load? Rich
