"I bought this boat two years
"I bought this boat two years ago being a first time boat owner and everything was fine till the back two cylinders over heated with no sign in the temp gauge. I am military and didn’t have the time to work on it myself so I brought it to a marine Mechanic in town. They rebuilt the motor from the ground up. Least everything except a new head. I now have 24 hours on it and I Supposedly got hydro lock last time I had it out. The guy that rebuilt my motor will no longer take responsibility for the motor, so I am fixing it myself. What can cause hydro lock? I believe it has to do with the flapper valve in the exhaust. Mine was wedged in there when I took it apart last. Is it possible to drill a new set of wholes above the existing wholes being the old whole is now oval shaped, and install a new flapper valve?
I am also having problems with the temperature gauge jumping to high temperatures and rapidly back down. Any ideas"
