I have a 2010 BF150 BANJ 1304288 The motor will run over 13 miles a hour for 5 minutes or so and then fall to an Idle with a steady alarm and only the green light on. The alarm doesn't stop until you bring the throttle back to an idle. I can run the motor all day at 12 MPH without any problems but as soon as I get up to speed it will run for a few minutes and then fall off again. I have replaced the fuel filters, empty the water separator, replace external fuel filter/water separator. Also the bulb stays firm. The only issue I can see is that the on board water sensor wires corroded off. I use the boat 2x week and have run it this way for several months trying to find the issue. I have also replaced the t stats. Water pumps perfect out the pee tube with a strong flow.
thank you in advanced for any suggestions.
