I have a new to me 26' Hewescraft Alaskan with a 2012 BF225. I took the boat out for the first time and the motor seems to run fine, but a serious lack of power. It took 200 yards to get up on plane and would only go 23 mph. I changed the fuel filters and replaced the intake manifold cover and the IAB control diaphragm because it was corroded and the valve would not open. I replaced the spark plugs as well. I removed 550 lbs of waterlogged foam and the water saturated wood decking.
The motor is still not running right. Full throttle in neutral is only 4000 rpms, but no alarms. Under load the motor runs at 3200-3900 rpms at full throttle. If I back off the throttle at full rpms fast, an alarm goes off, the motor shudders bad and rpms drop to a "Safe Mode?" The alarm is continuous and no lights are showing on the MIL. At speed I can see the green oil light is on, until the alarm sounds. The original owner called a Honda service center and they told him it was a plugged VST fuel filter and sent him a white plastic filter, which I believe is the VST air vent filter from all my research. Can't find the filter in the service manual. After the alarm goes off, I turn off the key and it starts up and runs every time with no alarm.
Any advice where it start now would be greatly appreciated. I live in Dutch Harbor and we do not have any outboard mechanics on the island, so its on me to fix, or mail the motor to Anchorage. Thanks, John
