I can see the water running through the exhaust hose because it floods the engine compartment. How do you flush it? I want to apologize, I am new at this and bought this boat used (1st boat). It has given me problems since I bought it. Seems like its been more in the shop than on the lake. I have been ripped of few times by the local dealer who had worked on it (over $3000 in repair bill). Just been so frustrating so any kind of help would be appreciated.
