I feel silly asking, but can I just hook up a hose an run water through the engine water passages or does the engine have to be running in order to keep water from entering the engine through the exhaust logs? I had assumed that the water enters the exhaust system down stream of the humps but I would feel totaly stupid if I hook up a hose and fill the cylinders through the exhaust.
I have a 460 with the factory exhaust logs on my Glastron CVX 20. When I got the boat the engine was not in place & I don't know what may have crawled in the various holes. Engine is currently on the stand and I was going to flush it out before putting it back in the boat.
