I just copied a old post because it it exactly my question and there is no better way to explained. It was never answered tanks please help.it i just got a used running engine for my bravo 250 and i noticed when i was putting it together that there was i small (maybe one inch) section of the central lip of one of the seals that wasnt there. i thought it had torn off when the p/o took it apart but wnen i looked at the old crank seal it was the same way. now i should have asked this question before i put it all back together, but i got impatient. was that void in the lip of the seal suposed to line up w/ something like a fuel/oil passage or does it not matter? i couldnt find any info online about the seal. the only post on changing bravo seals said it was a cut and dry change and didnt mention the void in seal lip. what can you tell me? thanks

I dont know what you mean?
Both seals are round, one has an outer grove that goes in to case?
Tanks so mutch after reading your reply a few times and looking at the diagramme I figure it out. The void in the lip going insid align itself with a oil grove inside the crank cover. Ouf I took me a some time. So it explains why oil and gase was leaking out the case. I bought the bravo last week and I´me restoring it. I am new to Yamaha snowmobile. have 3 elans skidoo’s can Fixe them blindfolded if someone needs help.
will do a complete restore of the poor 2008 Bravo that was shamely neglected. So will probably have more questions on the go. Tanks for thé help !
