Winterizing old 115hp Johnson

I have old 2 stroke Johnson 115hp. This is my first time winterizing. I am going to go ahead and drain the lower gear unit oil and replace the seals on the drain and vent ports. Where can I find the part number for the seals? What type of oil does the gear unit take? How much of it? Thanks for the help.

As far as winterizing, those old motors don't require much. You could idle the motor and cut off the fuel to it until it quits. With the newer 90/10 fuels, I'd make sure there's a stabilizer in the tank. I used to use portable tanks on my old motor where I could completely drain them for winter.
I assume you're wanting to change the tiny gaskets on the plugs when you drain the lower unit. They're just little $1 items. I'd start at a marine dealership. You could mail order them, but the delivery charges are too much.
I just use Pennzoil lower unit grease from Walmart @ $5.50 per quart. One quart will usually do it if you use a pump to put it into the lower unit. If you "squeeze" the bottles into the lower unit, it'll take 2 quarts.
If your motor is old, have you considered having the lower unit pressure and vacuum tested? That's the only way you can be assured that the seals are good on the motor. And it's something that needs to be done every few years.
