My engine (Westerbeke 27) started to fire up roughly and then finally died. I spent way too much time and $$$ (including replacing injectors) trying to figure out why before I made the leap to electric propulsion
. I sold the dead engine to a fellow who rebuilt it. Cost him $3,500 and he did all the work himself. He told me what had happened. Seems the head gasket
onto one of the cylinders I suspect this is what caused the rough starting. The engine was probably running on three cylinders until the water
finally cracked the cylinder head
. So you might want to inspect/replace the head gasket
after doing the compression test.
