Title: Jack Plates ?
Post by: Anonymous on April 18, 2006, 09:54:30 AM
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.
