Edson guidance says...
The Edson maintenance sheet says lube the steering wire/cable lightly with #30 weight motor oil. My steering was really tight a couple weeks ago.I removed the access panel and found the compartment full of standing water. You need to keep that small drain hole clear and the best way to do it is like Jim B said....using a hose and spraying in from the outside exit hole. Got rid of the water, used a little motor oil on the cables and all is back to normal.
