Sportmaster Lower oil drain and vent screw washer

[dogeatdog]

I am looking for a part number 19183 that is a "fiber" washer. I was told these are not made anymore and the replacement is a 19183-3. The new one is blue rubber but I have been told the yellow ones could work.

Is there a size difference between the blue and yellow washers? What is the best replacement for both the oil and vent hole screws for this lower unit?

The 19183 supessedes to 19183 3, if thats part it calls for then use that one.

The blue one is fine, the yellow one from the Verado is better.
