hello everyone,
Have the boat 3 years never had this issue . Does the mufflers have check valves inside? Cylinder #7 was hydro locked a few times. Changed risers, still happens. Lowered muffler still happens, and only happens when boat stops after a nice run. I let it idle for a while and still happens . It does not happen when in the slip running. No water in oil at all. I drain cylinder, spray some stuff in it to lube plug and white back and starts up no issue. So, I am wondering if there is a check valve or flap that is not working that is inside the muffler. So I know what to repair lol
Thank me all
Joe
