hi,
I have a 96 135 hp 2-stroke merc with a glass fuel filter under the hood, there is also an in-line water separator installed. There is a brown sand like debris on the bottom and in the screen. This was found after it had been sitting for 4 months and had not been winterized. In the past i have had pieces of the inside coating from the line that goes from the tank outlet to the motor but it was clear and flakey. This does not seem to be that. Does anyone have any ideas what it might be?
