Remove the gas line from the 4-stroke outboard and run it till it runs out of gas. Put a little more Mystery Oil, a detergent, into the gas than usual, sometime beforehand, in anticipation of running it dry. Mystery Oil helps clean the engine valve train of sludge build-up and coats the carbs/injectors w/ a light oil. (Mystery Oil is a no-go if you use synthetic oil.)
Remove the spark plugs, spray some fogging oil into each cylinder spark plug hole, rotate the flywheel a few times by hand wrench, NOT by key start, to spread the oil around inside all over the pistons & cyclinders, & reinstall the sparkplugs. Sparkplugs are very easy to crack and break.
Remove the propeller, grease the prop shaft w/ marine lube, and maybe spray paint the propeller if you want to. Wax up the outboard cowl cover and wait a day or two to rub off the dry wax. Go to McDonalds's and reward yourself w/ an angus third pounder with mushrooms & onions - hambungler........urp
