I have a 1968 22ft Flatback which is currently powered by an old Merc 115. I have found that the #1 & 2 cylinders are leaking water and have decided to repower. I have found a 1990 Yammie 130 but the shaft is 25".
My question is, what are your thoughts on using the jackplate (good or bad?) and is there anything I should be aware of? The transom is in good shape and the new motor is only about 50 lbs heavier.
Thanks for your help.

I have a 71-222 with a 140 suzuki 4 stroke. I love the motor and it has a 25" shaft. I feel like it helps because when you stop the old aquasports water tends to wash out the motor if the transom is low. I added a 10" Power Lift jack plate to set the motor back and help raise it. The lift works well my boat. I do have a transom that is higher than normal, but regaurdless the longer shaft helps keep the saltwater out. The only negative is that most mechanics say you lose some speed/rpms with a longer shaft. My boat runs 35/38 mph with the 140 four stroke. I had alot of critics tell me the motor was too small, however in the early 70's the largest motor was a 135/140 HP. I don't go real fast but I do save money both with purchase of a smaller motor and gas. Hope this helps. I have some pics in the photo gallery under fnichols or 71 aquasport.
