I sure hope someone can help me out, the tilt cylinder was leaking on my 85' 140 HP Evinrude.

I decided to replace the seals myself, it seems a pretty straightforward process, I was a mechanic for a couple of years so a simple seal replacement should'nt be a problem.

I've got the unit off, replaced all the seals but one...which happens to be the one I need. The cap on the tilt cylinder has a press in seal on the top, I've removed the seal but the BRP seal kit does not have this seal in it. I've looked online with no luck finding the part number to the seal.

I have seen a thread where the guy was told to replace the entire cap with a new one that comes with a new seal. The cap assembly is around $100, seems quite the waste to spend that much because a $2 seal is no good.

Does anyone have the part number to this seal and a way I can order it?
