I purchased a 2000 Glastron GX 185sf that is powered by a Johnson 130 2 stroke, same year. I was recommended to remove the VRO. So I add the oil myself no big deal. The engine runs pretty good except when I driving at a low idle it seems a little rough, when I accelerate it's fine. The other thing is how can I get better fuel efficiency. The plugs are new but I think it can do better I'm not racing around the bay in fact if anything I putt putt more and only get on it where permitted. My neighbor has a 4 stroke and gets great mileage. I read that the 4 strokes are more efficient, but I wanted to know if there is anything I can do?
