First check to see if there is oil in them. I would take the plugs out, squirt some oil in cylinders. If so put a battery in and bump the starter see if they turn freely.
If not locked up - See if you can suck the oil out. add fresh oil and change filter. Would run them with plugs out and coil wire grounded until you see oil up at rockers . If points you will need to service points/condenser dwell to get them running
Drain any fuel in the tank or run off a remote tank to start.
You will also need to check oil in transmissions assuming this is inboard. If it is an I/o boat change drive lube
Following up. Yes both engines have Walter V/drive transmissions.
One of the prospective buyers suggested that I confirm engines will at least crank over and are not frozen up. He suggested hand cranking and then maybe using "mystery oil" to soak after taking spark plugs out.
Would that type of oil work? How much should we use? at least videotaping that they actually turn over and run even using a carb starter spray should help with the sale giving a buyer some potential piece of mind.
Separate issue there is a lot of rust on the engines, pulleys, transmissions, everything pretty much. Would you recommend using CLR or naval jelly? Or Any particular solution I can spray over everything to at least rinse away the rust?
The port engine when we were fishing, had a high-pitched spinning type sound which resulted in having no turning of the prop. Motor was fine, but didn't allow us to go anywhere which is why we took it out of the water 10 years ago. I've been told that issue is either a coupler that has broken in between the engine and transmission or that potentially something inside the Walter V – Drive transmission broke and needs to be rebuilt. Any thoughts on that? Thx again
