The cable that your going to need has a 43BC designation (old Morse number)..
The Teleflex is a 4300BC
Hint; the "BC" stands for "Bulkhead" on one end "Clamp" on the other..

Probably going to be between 15' and 17', depends on where you mount the control dealio... That is an old style Place... You may want to look into a ride plate if you don't already have one... Many times the intake needs to be milled to accept it, but there are bolt on kits available.
The early Place Diverters have that snorkel hanging down and depending on how you hull rides can parachute a little bit robbing speed..
Still a great investment for overall performance of the boat.
