Wintering a 1972 125 hp outboard

[Mfribley]

I hate to post this and admit I have absolutely no knowledge however better safe than sorry

It's getting to be that time to winterize and put the boat up for the season and I have no clue what to do!!!!

When I was a kid we had an old 8hp Chrysler at our cabin we would use on the back of the boat, I remember every winter my dad would disconnect the fuel line coming in from our last fishing trip of the year and run it completely out of gas get it off the boat and disconnect the water tube to get any water out of the cylinder(s) and drain out the lower unit... And that was it..

Now years later I have my first boat with a much larger 125Hp Johnson that is older than myself and as I am going through those same steps I am questioning myself as to if these steps will be enough(hoping it's not already too late as it has dropped below freezing a few times already this month)

I disconnected the water hoses there was no water that came out of the cylinders or in the hose I drained the lower unit (going to have to get shaft seals in the spring) and drained the carbs

What else if any should I do

The motor is self draining if stored in the normal running position.---No need to disturb any hoses.-----Get the seal kit now and install it.---Or refill the gearcase with any motor oil to prevent corrosion of big $$ parts.----Refill with type- C gear oil labelled for ellectric shift after the new seals are put in.

so no need for marine antifreeze also i am looking at this diagram of the Johnson gear case and trying to figure out what part number the seals are i need to get i drained the lower unit and it was milky grey

Water in that unit is not good. A pressure and vacuum test will usually reveal the leak. It might just be the seals on the drain/fill and vent screws. But there are several seals that can leak.

You need to refill the case with oil to prevent corrosion over the winter, there is still water in the case, mixed with whatever oil is still clinging to parts.

Fuel stabilizer added to tank and engine run to get treated fuel into the carb fuel circuits is a common practice. Disconnecting the fuel on a multi carbed engine usually results in one carb running dry before the other(s) which can result in a lack of lubrication in cylinders fed by the dry carb. Fogging oil is also recommended for storage of more than a couple of months.

Nope, when one carburetor runs out of fuel there is plenty of oil all over the parts.----And dry air will not cause any problems whatsoever !!!
