When I try to throttle up and bring the boat on plane, at 2,000 RPM the motor starts to stumble and an engine alarm goes off. Things I have eliminated, wires to all the sensors are good, I have changed the fuel filter twice, the impeller is good, gauges read excellent, 13.5 volts, 165 degrees, 40 psi oil pressure. What are some more things to check?
