TRS to #3 is a direct bolt on. It will raise your X dimension and you
will pick up some mph. Props are not cheap. A friend and I were just talking about doing the same on his boat.

F'ING COMPUTER!!!!!!!!!!!!!!!!!
I just typed out the whole process of changing to SSM3 from TRS & got booted before I could post it.
In a nut shell....
Gut your engine compartment
Glass up transom (at least 4-5" of the bottom of the existing hole)
Carefully measure out the drive (drive shaft to prop shaft.
My Cig has no steps, pads or notches in the bottom & we went with 4" prop shaft below the bottom.
Most riggers will suggest 3-1/2 to 5" with 3-1/2 being the minimum to get on plane without alot of trouble.
Find someone (Lake X) with a SSM jig to get all the holes drilled right.
Your engines will have to be moved back approx. 3" (SSM trans tailstock is shorter than TRS.
Hang motor/s from hoist to measure your new hight. Make new mounts with 3/8" alum angle iron.
Invent shift cable brackets & misc BS.
Gain: 4 mph, awsome rooster tail and no more TRS bombs going south when your far from home!
Thanks Russ Houston & Expo for all the help!!!!!!!!!!
Any questions, pm me

DJD and Gary are telling it like it is!!! I did it to my old 38 Fountain...just had too much HP for the TRS drives. The #3's were extremely reliable and worked well....I then took the 3's off and put on a pair of big shaft 4's and look out....five more miles per hour, an awesome rooster tail and a lot slower to get on plane. It is a fairly intense project, but it does work. Best of luck!
