I have a volvo penta SX-M drive, I noticed two tiny pin holes in the exhaust bellows. I will probably replace both the exhaust and the universal joint bellows both . The repair manuel is on the way, I know I have to pull the drive, are there any special tools I need, or any tricks that I should know about. I have been browzing the subject on this site but it seems I can only find info on mercs. Thanks
