My 2005 150 opti has been giving me few probs. When i run the boat the alarm comes on about every 10min or so and gives a few short beeps the goes off. Also the boat used to run about 5500rpm and 37mph, now it wont go past 4000rpm and 25mph. I changed the fuel filter recently and had no problems till last time went out. I also have good water flow pissing, and only run no ethanol gas. Anyone have any ideas? oil,water, overheat???
