I have 2 50hp Mercs. One is a 77 model the other is a 82 I beleive. The 82 has T&T. My question is due to the fact that the lower unit on my 82 is in pretty sad shape including the upper and lower mounts can I swap the mid section,clamp and lower unit off of my 77 to my 82 and then install the t&t unit. The reason i would be doing this is the 77 is way to gone as far as rebuilding is concerned and the 82 runs like it was brand new. Thanks for any help anyone gives me.<br /> 1FASTLASER
