I recently purchased a boat with a 115 EFI 4 stroke johnson motor 2003. I dont know how to winterize it. I am familiar with winterizeing a 2 stroke. Where would I fog it or is it nessary? Thanks for any and all help in advance!
 
Welcome to the Forum. I would make sure there in no water in lower unit lube. Then make sure all fuel is run out of fuel pump and injectors. If there is ethanol in your fuel you should completely drain the fuel tank and use up the fuel in your car or truck. I would definitely fog the intake as your spinning the motor to run the last of the fuel through....why? 4 strokes have very little residual oil in the cylinders, unlike a 2 stroke.
