Need more main jet seals

[hugh]

I seam to have lost the part number for the fat o ring that works to replace the main jet seal on the smaller Johnson/Evinrudes. Anyone have the info? I thought I bought enough last but, more and more and more… outboards

Hugh,
I have the book in front of me. Tell me an example to give you a part number. Here is one seal #301999 Does that look right?

[hugh]

The factory part is 0344037 1963 Johnson 3 hp and such. $5 ea. It is flat rubber with a hole in it like if you cut 1/4 inch off a fuel line. I have been using a fat O ring that can handle the fuel. Someone in the club listed the o ring part number 4 or 5 years ago. I bought 50 of them, but ran out. super cheap.

For off the wall applications or hard to find Orings, this store will normally have what you need and shipping is sometimes better.

Same here Pappy. I checked it out and looks to be another good source, so I bookmarked it.
