I first used the larger o-ring 3855081 that also fits the middle vent hole. This o-ring promptly tore before I even got the bolt all the way into the drain hole.

I then ordered the smaller o-ring 955981. This part number seemed to work, but after two weeks of setting in storage with the outdrive down, there was a 4-5 inch oil spot on the asphalt under the skeg.

How do I know which part number o-ring is correct?

It may be possible that the oil on the ground was residual from the mess I made changing the outdrive lube, but I did use the boat after installing the smaller o-ring before parking it at my storage spot. I figured any residual lube would have been washed out.

I used to order these kits as you only want to use them once. The dipstick maybe twice.
