Question about Boating
I have twin 1988 mercruisers in a 28 ft sea ray.Was running great then the port motor just stopped running.Took plugs out and found water in cylinders on left side.Right side has no water in plugs.Changed rizer gasket wasn't problem.Could it be the head gasket or??????????HELP..........
There are Flapper plates in the exhaust. They can burn out especially when running with the Muffs for winterizing. Then problems shows up first time you take it out. Usually this problem does not show while boat is moving. The bad flapper allows water to draw up into the engine like having a straw in a drink.
Sometimes when decellerating or Transom to the waves a rush of water goes past failed Flapper and into engine. Instant Hydro lock.
Its easier to change the Flapper than removing a head and you know which exhaust to target. When you get the Flapper out, the parts guys can easily tell you if its junk.
