my seacraft has a 2000 yamaha sx200txry. I have been told my motor has 3 gas filters under the cowl.When I take off my cowl I see the obvious one on the side of the engine.Does anyone no were the other two are and the part numbers.I am draining my tank and changing all filters for I think I may of mix some E-10 in my tank. Thanks Keith

The OX66 motor only has the one under cowl It's about $35 now. The red ring floats in water but not in gas. Be careful when reinstalling it that it sits on top of the flange. There is afine mesh screen on the bottom of the HP filter that can be cleaned. The LP fuel pumps are also a replaceable item ~ $30/ea.

there actually is another one under the cowling; however, its is not particularly easy to get to. it is inside the Vapor Separator Tank(VST). I think the part is about $100 and it is usually about 1hr labor to have it done. unless you do most of your own work, I would suggest having your mechanic do it. when I first switched to the E-10 I had some issues with stuff getting through my fuel/water separator which clogged this filter and gave me a giant headache.

That is the fine mesh screen on the bottom of the HP pump.

I just did the lp pumps, filters, and hp pump screen cleaning. I tried to take pics but daughter had camera locked in car

I did not have a manual. I removed the entire VST tank after draining and held the flange in vise. The screws are loctited in and the heads will strip easily. You will either want an impact screwdriver or hammer the hand screwdriver so as to shock the loctite. You obviously can't put heat on it, it's been full of gas/oil. The o-ring is all that needs replacing ($40) unless you opt to replace the screen. I cleaned mine with spray cleaner and light compressed air. It's like the permenant coffe filter material and kind of 1/4 turns off. The lp pumps and filter are straightfoward.
