Hope someone can help me out.  I have a 79 Rogers with a 454 big block and Berkeley Jet.  I was in Laughlin last weekend and I came into some problems.  The engine was running fine but as I headed out of the Marina, it seems as if I sprung a water leak.  The spray looks like its coming from the cylinder head/ flywheel  area but I'm not completely sure.  This caused my boat to eventually break down and I had to get a tow.  I'm not an expert in jet boat cooling systems and could use some advise on where to start troubleshooting.
