Alright so I think I already know the answer to my question but I would just like to verify. I recieved my new inner transom plate and the rear engine mount is slightly different. There is a rubber washer installed on the assembly insted of the fiber washer that was original. I am assuming the rubber takes the place of the fiber washer and re assembly should be the same as original. The engine is a 2006 496mag ho and it does have the newer style mounts, so no spring washer, just a stainless washer. Thanks guys!
