1989 force filter screen

[isis]

Last week i took the boat out and when i power up on the engine it didn't seen like it was getting enough fuel.I took the fuel filter off( a normal car fuel filter you buy at autozone) and ran okay.I got home and took the stock screen filter mounted on the engine off and it look like-white, brownish sawdust gunk.I ran it today and notice it was missing,so i took the screen off again and same thing.It had gas sitting in it last winter but i drain it all out but did not did not clean the inside because it did not look gum up.I also took the siphon brass tube out of tank and was clean.What advice do you recommend?Also can i use a regular car in line fuel filter on the motor?The stuff on the screen is not hard gum to get off.It comes clean spraying gum.

You can use the regular cheap plastic in-line auto filters.

It sounds like you may have been a victim of mixing gasoline brands. You see, recently, some brands have started to use ethanol and others still use another older additive (MBTE?)) In a car this doesn't cause problems. but in a boat in the presence of moisture, if the two different gasolines are mixed, they cause a gum to form and this will clog up filters quite quickly. The cure for now --until all brands are changed over to ethanol additive--is to stay with one brand of gasoline in your boat tank.

Thanks frank,you are the man.I thought it looked like moisture but i could not see were it could come from.Do you recommend anything to put in the gas tank that is safe for the outboard?

No! There are no additives that will prevent this problem. Like I said, just stay with the same brand.

By the way: I fixed a 90hp Merc for a guy. His carb bowls were filled with what looked like jello and it was holding the floats up, flooding the engine. Once I cleaned it out and let it dry, it looked like a granular tanish powder. I told him the same thing--Stay with the same brand gasoline.
