    oily substance?

    There is this white oily substance on the side of my pto carb. I just swapped everything into this new hull and have ran a tank of gas threw it and there is this stuff on the side of the carb what is it and wheres it coming from? Because it has new intake gaskets.

    The substance is fuel/water combo, I had this on my pro 785, turns out one of my fuel lines was spraying a mist of gas when running and the water being sloshed around was mixing with the gas and forming the milky greyish/white paste. Check carefully for fuel leaks. What type of flame arrestors are you using? What model ski?

    Another thing to check would be the fuel mixture screws there is an o-ring on the bottom of them, not sure if it would allow fuel out or let air in but it might be worth looking at, just make sure you count the # of turns in to a lightly seated position before you remove them so you can return them to the original settings.

    I'm not getting that much in my hull either but after a hard ride you can lift the seat and see where the water was splashing around, I also have a cover over my coupler.
