winterizing boat motor

[mikeandronda]

I know its a bit early yet but I was wondering what a person needs to do to winterize a 2 stroke boat motor. I have a 10hp mont. ward ( I beleive ) 1975 motor that is in excelent condition and would like to keep her that way. Thanx in advance.

Middleground:<br />The fall gearcase change was suggested to me to prevent leaving any water in the gear oil during th winter. I was told that if it freezes, it could do some damage. Made sense to me.<br /><br />Charles

Amen on fall change of gearcase lube. I didn't on a Merc Mark 5 and it froze and broke the threads in the lower unit.<br />Jim

Re: winterizing boat motor

If you live in a relatively warm area (Charleston, SC)and plan to store your boat in the garage over the winter, what steps are necessary to winterize the engine? I have a 25 hp Johnson outboard that is 1-2 years old.<br /><br />I'm thinking about lubrication and draining the gas out of the engine- could you further explain decarbonizing? Oh, and the gearcase oil....

My thoughts ! not a big fan of decarbonizing.<br />always caused more problems than what it prevented<br />or did.<br />Fall/winter <br />Sta-bil in tanks and run to open thermostats <br />Then change gear oil <br />I pull plugs and fog oil in cly's turn over by hand and fog again,put plugs back in <br />Grease zerks <br />grease prop shaft spline<br />Put motor in full down position alows water to drainTake battery out<br /><br />Spring/start of season<br />Change plugs<br />Change water pump if needed<br />charge battery<br /><br />Just my ways <br /><br />Rich<br />Chk
