How do you PM or winterize a 15 hp johnson outboard?

Question

Just looking for ideas on Preventative maintenance or winterizing my motor. It is a two stroke.

Answer 1

Where are you located to be winterizing your boat now??  Anyways, put some fuel stabilizer in the fuel and run it before you store it.  If you have a water pressure gauge or speedometer you may want to purge the lines although I never have with no problems.

Answer 2

The last time you use the boat for the season, disconnect the gas line from the engine while it is idling and let it continue to run until it uses up all of the fuel in the carb.  When it begins to konk out, choke it to use up any remaining fuel.  This will prevent your carb  and fuel system from gumming up during storage.  Next,  when the boat is hauled out of the water,  tilt the motor down and let all of  the water drain out of it to prevent damage from freezing.   Then, drain the lower unit fluid.  Look at the old fluid coming out and if you see water drops or the fluid is milky colored,  replace the lower unit  seals .   If it is clear and no water visible, refill the gear case with lower unit lube.  Finally,   remove both spark plugs ,  spray some fogging oil into each hole and pull the starter rope several times with the plugs out.  This will coat the cylinders with oil and prevent rust buildup,  If the plug tips are black,  put new ones in,  otherwise replace the old ones.  Don't pull the starter rope any more.   Store the motor in a warm dry location.  My son has  a 1982 25hp Johnson that we have winterized this way since new.  It starts on the first pull almost every time and the only parts needed to be replaced over the years  were spark plugs, a prop shaft seal and a starter rope.
