hey guys,
I did the regular service on my 2005 DF140, oil and filter change, spark plugs, leg oil, greasing the nipples and the throttle shifters inside the motor and also replaced the Racor filter. There’s 360 hrs on the engine and we took it out last time before the service it was purring like a cat.
When replacing the Racor, I filled it up with non-marine regular gas (3-4 months old) and fired up the engine. The motor sounds like it’s running pretty rough. I took it out on the water and filled the tank with fresh marine grade gas but it was still limping, not going over 3200 rpm and even at that level, not going over 8 knts/hr.
One of the forum members here who’s pretty knowledgeable with these engines was kind enough to send me copies of the shop manual which I used to drain the VST and the HP filter. I also drained the Racor filter in a clear jar and there was no sign of water or debris in the fuel.
Added some Seafome to the tank and let it run idle for good 20-30 mins. Still sounded rough and wouldn’t go over 3200 rpm when on the water. There’s also a lot of fuel odour which makes me think that the motor has put itself in the safety mode.
I’m pretty much stuck at this point. Any idea what else could be the culprit? I’m trying to avoid taking it to the shop in the middle of this Covid cr*p but I also don’t want to cause damage to the motor. Any tips would be highly appropriated.
