My boat is a 2011. I dont have the screens. I did run water and Dawn as recommended in the video. I opened the spray bar valves and flushed them several times.I back flushed the drain for the pump out. When I bought the boat two years ago the black filter was not in place. I cleaned it up and siliconed it in.Everything seems to be working like new.Thanks to all for the assistance.Proud to be associated with the Bass Cat FamilyLast edited by Tiger Smoke on January 22nd, 2017, 11:51 pm, edited 1 time in total.
