Thanks for the starting point. I pulled my plugs and they were soaked. I tried to turn the engine over and still the starter just made noise. I then removed the fresh water intake pump and put a 15mm socket on the splined shaft and gave the engine a few turns manually. The water then pumped out of each cylinder with each manual turn of the crank. I sprayed a little PB Blaster in each cylinder to displace any remaining water. I purchased and installed new plugs. I put everything back together and it turned over. It took a bit but then it finally caught and started running again.
Unfortunately, there seems to be a dead spot in my starter gears seem to have a dead spot. So the next time I tried to start it the starter just made noise. So I pulled the water intake again, put the ratchet to it and manually turned the engine a little. The starter then was able to engage and start the engine. I don't want to keep pulling the water intake every time I land on this dead spot. Does anybody know of an other way to manually turn the crank a little bit with very few tools?
