Bellows question

[splatter]

I bought a new outdrive which should be here saturday . The old outdrive had leaked gear oil into the drive shaft bellows . Sat like that all winter . The bellows looks good but I'm concerned that the oil may have damaged the bellows . So should I change the bellows also . They were just changed 4 years ago .
Thanks

Well,the oil should not have hurt them,but after 4 year's they should be checked thoroughly for crack's weather checking. I'd just replace them myself just to be safe.

Re: Bellows question

4 years is real close to the life span of a bellows

Re: Bellows question

I would probably do ahead and do it. That way you start with everything new. You can get it done today and tomorrow before the drive arrives.

I disagree. Inspect the state of the bellows, instead of just replacing it because its been X number of years. You'll see the cracks and it will start looking dried out, just like an old car tire that has dry rotted. People I know are getting 7-8 years out of bellows. Mercruiser does advise a much more conservative number, but like everything, that most likely to limit liability for those few cases. Inspect and make an informed decision.

I agree the oil will not affect the rubber at all.

If you do need to replace it go with an OEM bellows they fit much better and are easier to instal.
