I searched the forum for info. pertaining to this and found one post concerning a Ficht motor and possible fuel contamination, but I'd appreciate some opinions on my particular situation.
After splashing for the season and 20-30 mins. of idling and slow speed cruising, my 2000 Evinrude 200hp tripped a CEL and went into "limp home" mode. Restarting the motor caused the CEL to go out, but then re-tripped 1-2 mins. later.
Suspecting water in fuel, I changed two filters; one between tank and motor, one on the motor itself. Managed 15-20 mins. idling before CEL tripped again. Boat was winterized with a full tank of fuel from a gas station (i.e. not @ the dock) last Fall, although it was 60-90 days before I added the Stabil.
I siphoned 1 liter of fuel from the fuel line squeeze bulb and let it sit. 1/2 hr. later it looked like very
light iced tea and there was clearly 2-3 tablespoons of water on the bottom.
Next, I put the fuel line from the motor into a 5 gal. can of fresh gas and a new filter on the motor. The motor ran fine at idle and low speed for 20 mins., but about 30 secs. after I powered up @ 2500-3000 rpms, the CEL tripped.
I know I NEED TO PULL THE CODE, and I am having the fuel filtered/recirc'd to clean it, but based on my "test" with new fuel, there must be something else going on here. Are there any obvious culprits I should be targeting? Any suggestions would be very appreciated!
