Re: 1995 force 120 outboard engine winterizing
Outboards are generally pretty easy to winterize. If you run the motor in saltwater, you will want to make sure you have flushed the motor to avoid corrosion ( should flush it every time you take it out of saltwater anyway )
Beyond that, drain the lower unit oil, replace. You can fog the cylinders, disconnect the battery and drain the fuel. The longer the boat is going to sit unused, the more important it is the deal with the fuel side.
I use my boat every season, and as soon as the lakes open up again, I don't do anything with the fuel system. I winterize by disconnecting my battery and drain/refill the lower unit oil...that's pretty much it.
The more important thing to do is to do a good visual inspection of everything now that you have a chance to fix it since you won't be tempted to use the boat. If you have bad lower unit shaft seals from getting fishing line wrapped up in the prop, get it fixed. Take off that cowl and make sure you don't have any bad fuel lines ( cracking rubber ) and make sure that your electrical connections still look good, are tight and not corroded. If something doesn't look right, investigate it further.
And store your engine in the upright position so that water can drain from the leg properly.
