Re: yamaha 115 4-stroke gas in the oil
I am not exactly sure what the engine will turn up, I do not have a tack on the boat, but again, the engine runs excellent. At trim and throttled up it will nearly scare you. There is no problem with performance, compression, smoking, etc. Simply, after any running time it accumulates gas in the oil. Is there a sensor similar to what is on a car, i.e. cold start sensor that tells the computer to dump gas until the engine heats up? Maybe some sort of sensor that dumps more fuel than needed and that extra fuel is not burning off. Not to sound redundant, but you would never know there is any problem, performance is excellent, but for, checking the dip stick. For example, after the last chemical shock in an attempt to rid the engine of any carbon build up, I changed the oil, placed the measurement at exactly mid-point on the dip stick; ran the engine for less than an hour, allowed for wait time, ran it again the following day, stop and start with little idle for a couple of hours, check the dip stick and the oil/gas capacity moved up the dip stick to the upper cross-lines. (Suggesting about a 1/2 quart of gas accumulation). Same result as the last time.
