It appears to me that this is a very poor design and would take major engine disassembly to do this, not something that could be done at sea in an emergency. Any advice would be appreciated.

How old is the engine ? Looking at Yanmar's web site they say that all J Series engines have the water pump at the front of the engine not the back. You don't by any chance have one of those strange setups where the engine is actually installed backwards ? (No I'm not pulling your leg, it's a serious question.)
