I have a '79 Beisemeyer, 21 foot, with Hardin water cooled exhaust manifolds with risers on them. I have been having problems with water getting into the cylinders when the boat is sitting in the water. Usually I anchor with the ass end of the boat towards the shore, so it can't be a wake problem.
I know that the gaskets between the riser and manifold are leaking, as they are spraying out water when the engine is running. Not much, but they are definately leaking. Here's the problem. I am trying to get the two apart from each other so that I can replace the gaskets. What is the best what to separate these two pieces? Attached is a picture of the parts, if anyone can help, I would really appreciate it.
Also, could this be causing my water in the cylinder problem. Yes the flappers on the transom are good, so that is not the problem.
Thank in advance for you help.
