GAS IN OIL 150 four stroke?????????
It is amazing to me how many people have posted on this subject, and nobody really has a cure. Unfortunately, we just bought a boat in Costa Rica with twin LF150TXRD's. The engines only have 890 hrs on them, and the survey came back perfect, perfect compression, and no fault codes. Before we ran the boat we did the full 1000 hr service, plus had the injectors cleaned. After 50 hrs of service, both motors have gas in the oil, about 1 inch above full. Everything that I've read is contradictoy, and our local Yamaha dealer in Tex. says they have'nt run into this proble......B.S.! It seems like Yamaha says everyone isn't running their engines hard enough, but........that may also happen if you are over wheeled????????????? Don't idle too much!!!!! Why would anyone put one of these motors on a fishing boat? Some say use a hotter thermostat, but some say not to. As much as I've read I'm more confused than ever. Has anyone actually cured this problem? Thanks
