The 10-71 was the direct replacement for the merc trans without having to move the engines if I remember correctly. The 72C requires the engines to be moved in order to accommodate and since I was only running about 675HP. I didn't want to move them and went with the built 71C Hubers.

Any boat with a merctrans that wanted to upgrade to a borg Warner c71 or c72 had to move the motor forward at least 7inchs to fit the borg trans. I had 2 boats with Merctrans and was going to do the swap but didn’t have the room in front of the motor.

Ok. It was a long time ago. I had the 71cs in boat when I bought it. I know they had to be moved if I went 72c. So I just built the 71cs to 925 specs which was the max you can do to the 71cs. Thanks for the clarification. It was in my Old Mistress that I Refurbished a long time ago.

I would concentrate more on looking for a good solid, well maintained boat than what drive is on it. If you intend to put big power in it and fly it you can destroy any drive. There are many posts on here and other sites with bad things to say about every drive produced. TRS and Bravos are both proven when maintained and not over powered. There are a good number of Cigarettes out there with TRS from day one still running strong. Parts have been discontinued but if you search you can still find drives. There is also The Konrad option. Good luck and make sure to spend the money on a good survey.

If your interested in a 35'..........might be buying a new boat soon.

Pete, you thinking of selling? Moving up in size, staying the same ,just newer?

Since my outdrive is at Colabella in FL. the 35 cig has been down, was fortunate this past weekend to be out (with family) on a beautiful cruiser on the Hudson....leaning maybe?
