Well, finally got around to using this kit, took the gimbal bearing out and it's seized... Will not move in the housing regardless of the force used. We also noticed aluminum shavings in the grease hole so that is likely the problem. Will have to replace the bearing with another one. Very hesitant to purchase any more Sierra products now...

Nice kit. Includes all the needed parts for a sterndrive/outdrive service. Would recommend Permatex cooper silicon caulking for the paper gasket and Permatex "hightack" adhesive for the bellows. Both available here on Amazon. Cooper silicon seems to seal better due to the age of my outdrive surfaces. I also use it on the outdrive side of the u-joint bellows.

Missing both bellows and gimbal bearing. Didn't open box till we had the ourdrive off. Had to go to local shop to get parts to finish. Returned this item. Make sure to check contents as other reviewers have had the same missing parts problem.

Used this kit to service our '78 OMC cobra. The old bellow had leaked got water in the gimbal bearing and U joint.. The kit came with all the gaskets that needed replacing. The exhaust bellows in the kit are the ones with slits along the bottom. I was hoping for the solid exhaust bellow as that's what the boat had originally but this will do.

This is exactly what I needed to maintain the OMC Cobra. Great value for a full kit, you will need a tube of bellow adhesive.

This kit was an exact match for my 89 Chapperel with a omc cobra outdrive with a 4.3L engine. Gimble bearing was included as well. This kit met an surpassed my expectations and I would definitely recommend this to anyone. Thanks
