I have been having a troubling issue with my Yamaha 2001 250 EFI. I have had a problem with the unit reducing RPM’S when I hit a wave. It seems to throttle down to the safety low RPM mark of about 1500 after hitting a moderate wave. It clears up after I stop the engine by cutting it off for a few seconds and restating.
I had this problem once before but solved it with replacing the engine oil tank float switch which was faulty when it was struck. I am not getting a oil flashing lite problem on the tech. I also know I have good fuel pressure to the injectors and I have just replaced the O2 probe.
I have checked all the electrical plugs on the engine and battery and engine control connections.
Has anyone had this problem before?
