First thanks to all for the great information to be found here, as a new old boat owner this is a great resource.
I'm trying to get a 69 Sea Ray 180 I/O back in the water. Mercruiser 160 engine, and outdrive.
Boat was bought as a project, story was that the motor had been re-built/bored 30 over and then stored for 10 years. Motor would not turn with starter. A bit of transmission fluid in the cylinders along with some time freed the motor right up and a bit of emory cloth on the points along with new plugs and motor would start on ether but not run (carb is still a mess). A dozen of so attempts to get things running with the muffs hooked up (including some fuel into the carb to sustain 10 second runs) and now there is water in the oil. Drained the pan and got about 2 1/4 gallons of grey oil out. Pulled the riser and its toast, broken down all the way to the inlet. Pulled the head and gasket looks good and there are no visible sighs of any leakage on head or block, no cracks on cylinder walls. I know I'll need to check the manifold for leaks but before I go there I have a question. Could a leak in the exhaust jacket (bad riser) cause the engine to ingest a gallon of water into the oil pan this quickly? What are the chances of a hidden crack in the block between the oil and water jackets (block drain was open when I received the boat)?
Thanks,
Steven
