I have a 1990 40HP johnson, J40ELESR, and have some questions about the fill and vent plugs. The OEM parts list shows the same o-ring for both the drain/fill plug and the vent plug. All of the sierra parts that replace the drain/fill plug have a magnetic tip and a allen head with a plastic washer(which is what is currently on my motor). The vent plug is a small slotted head with a small red washer on the plug. If you search the part # for the fill/drain plug it shows a picture with what I have(magnetic tip with plastic washer) but the parts list also looks like it calls for a o-ring? Same with the vent plug, the o-ring is on the plug but also shows same o-ring for the drain/fill plug? I cant find a part # for the just the small o-ring on the vent and a part # for the plastic washer on the drain/fill? Any help? I've read through past posts about these gaskets and it adds to the confusion.
