I have a 1995 Sea Ray Sea Rayder 120 hp sport jet. I put the boat in the water and discovered that i have poor acceleration. the tachometer under load stops about 3500 RPM and my speed is under 4 MPH. at full speed the boat should be close to 40 MPH at 5500 RPM. Nothing is clogging the impeller and the wear ring is at a tight 30,000th where it calls for 25,000th. The boat mechanic stated that he did not have a clue what is wrong with this!!! can Anyone Help me...... jaimesahn
