Hi again; I received some good advice on this forum in the past, let's see how good you are:rolleyes:
Three bf 225's in my area (mine and two friends) are having the same problem. Model years run from 2009 to 2011. Engine hours are not the same. My 2011 has 650, one 2009 about 1,000 and another 2009 about 1,500 hours. All developed this problem last year.
All are used primarily for trolling (3mph). Start motor at pier and run to fishing grounds (30 min) with no problems at all. Drop to trolling speed and troll for 3,4,5 hours. Pull all lines and when we power up, motor stalls, shakes, alarm goes off for an instant, motor drops back to "safe" speed (3 or 4mph).
We drop throttle back momentarily, then throttle back up with no problem. What's up?
All of us thought replacing the Hi-Pressure filter (VST?) this winter would take care of the problem. But it hasn't.
It acts like it's starving for fuel. We have tried pumping the bulb before powering up, thinking the motor was sipping fuel while trolling, and it needed a bigger Glup in order to power up. This isn't working either.
We tried powering up very slowly, allowing the fuel consumption to "catch up" with the increase in speed. That didn't work either.
One of my friends tried putting it in neutral, revving the motor (takes fuel fine), then powering up. It still stalls.
Is it a "vapor lock" of some sort?
Has anyone else had this problem? We all get fuel from different sources. Some on the water (marina's), some trailer and only use "gas station" fuel (10% ethanol).
HELP
