My 1991 Suzuki PU140 (DT140 with a jet pump vs a propeller) will plane out at 4600 rpm and run fine at that speed. However, when I increase throttle to 5100 rpm the motor starts stalling out and changes from 4600 to 5100 to 4600 to 5100. When I decrease throttle back to 4600 rpm the motor runs fine on plane.
Background: The motor has acted this way since I changed fuel tanks. The current tank is a plastic 12 gallon Spectra. I have checked all hose clamps along the fuel line and all are tight. Any suggestions as to why this 1991 Suzuki PU140 is acting up would be appreciated.
