You mean all this?
①Wash the engine exterior and flush the cooling water system thoroughly
with fresh water. Drain the water completely. Wipe off any surface water with an oily rag.
② Use a dry cloth to completely wipe off water and salt from the electrical components.
③ Drain all fuel from the fuel hoses, fuel pump, and carburetor, and clean these parts. Keep in mind that if gasoline is kept in the carbruretor (yes - this is the spelling in the manual) for a long time, gum and varnish will develop, causing the float valve to stick, restricting the fuel flow.
④ Remove the spark plugs and spray storage oil (available from an authorized dealer) into the combustion chamber through the spark plug holes while slowly turning the motor over using the recoil starter.
⑤ Change the engine oil.
⑥ Change the gear oil in the gear case.
⑦ Apply grease to the propeller shaft.
⑧ Apply grease to all sliding parts, joints, nuts, and bolts.
⑨ Stand the outboard motor up vertically in a dry place.
Perhaps I should have waited until after
I retire to get a boat.....
Been a bad week for me and engines. I managed to kill my equally abused lawnmower by filling the air filter with engine oil (another wrong-side issue....).
