Seal, which way should it go | Page 2

Ok, so I took a run to my garage and had a better look at the seal. First, yes there is a spring inside and it is on the inside lip in other word if you are looking at the seal with the # facing you, it would be the second lip inside. That lip is also different than the other one. It is made more like a V shape. The other lip closest to you or I should say closest to the face of the seal with the # is more like a wiper lip and is shape going outside. I took some more pics. So if logic stands, the lip with the spring, shape like a V should be the oil seal and the other lip should be the one stopping the contaminant from going in which mean the seal is wrongly install. Your thoughts please.

tensioning spring around the sealing lip to the inside

[/ QUOTE ] The diagram on page 231 of Vyv's link appears to show the seals with the lips both facing down (ie top one inwards lower one outwards) but the text in paras 13 and 15 on page 269 indicates, I think that they both face inwards. However that refers to a diagram of 6 to 15 hp models in which the two seals appear to be different!

This sort of confusion is why these third party manuals are so poor. They attempt to cover too many models.

FWIW the crankshaft seals in my Evinrude both face down. ie the top one faces inwards and the lower one outwards. Clearly and specifically shown on the parts diagrams.

I would interpret the diagrams in the mercury parts list
