Well fellas, I need some help. I have a racor system in my boat and it has always done what I've asked of it. I have a '04 Yamaha 150 2 stroke outboard. I had the spin on filter w/ sight bowl on the bottom. When my engine started having carb issues (not caused by the racor) I took the boat to my buddy's dad's house because he has a nice big shop. It just made sense to work on it there. Well, we cleaned the carbs and I bought an el cheapo wal-mart H2o filter thinking it was a temporary move until I could get a new racor filter. I took the racor filter and sight bowl off and left it at the shop. Time passed and I put the filter on the back burner. Well I finally got around to wanting a new racor but my buddy's dad threw it away! So, now not only do I not have the sight bowl, but I don't know what model # filter to replace it with. I want to go back with the sight-bowl unit because you can drain them really easy without having to spin the entire filter off. I'm hoping someone can say, "oh you need this model # for your Yamaha." Please say its true.
