Question

How to winterize a 90 hp marcery outboard moter ?

Answer 1

Flush the engine with fresh water. For this use flush muffs or similar device attached to the raw water pickup.

Wait until all water drains from the engine.

Wash it with soapy water and rinse thoroughly.

Disconnect the fuel hose and run the engine until it stops.

Make sure that all fuel is drained from the carburetor so that evaporated fuel doesn't build up deposits.

Use fogging oil to lubricate the cylinder walls and pistons.

Use water-resistant grease on propeller shaft and threads.

Change the gear-oil in the lower unit.

Slightly lubricate the engine exterior or polish it with a good wax.

Answer 2

don't forget to put the cups on it when you run it out of the water.

Answer 3

I suppose you mean Mercury!?   If you have a built in tank w/ fuel left in it, stabilize the fuel per instructions on the bottle, and run the stabilized fuel through the motor for a few minutes.  With the boat out of the water, tilt the motor all the way down to make sure no H2O is left in it to freeze.  When spring comes, I'll usually pour 1 qt. per 40 gal of 2 cyl oil in the first tank and run that out.  Then I'll run 20 or so gal. of Premium w/ a carb clean additive.  Good Luck!
