Kicker Shaft Length

Hello again
I'm putting a Honda 9.9 kicker on my CC 23. How does one determine the shaft length? My 135 measures about 26 inches from the transome to the center of the prop. Would that put me in the 25" shaft or are the Kickers higher up than the regular motor.
Any comments about the difference in performance of the honda BF and BFP?
Thanks
Hank
 
As I recall, the shaft length is more closely approximated by the distance from the top of transom to the bottom of the first plate on the motor above your prop but probably won't be exact. That is, yours is more likely a 20" shaft motor.

It also should be designated by a letter in the model number on the motor. You should be able to find the length code for your year on the web or I'm sure somebody here will have it. Try here:

For a kicker, you should measure the height of the transom where you are going to mount it, to the bottom plane of the boat and get the next longer shaft length e.g. 19" = 20" kicker shaft. This is general. There are lots of ways to make longer or shorter shafts work satisfactorily with set backs and aux. motor mounts. A good goal is to have the first plate (Cavitation Plate) mounted at the same plane as the bottom of the hull in the down position.

This is very general (any boat stuff) as I do not have a 23 nor a Honda. So I will defer to any corrections.

I was under the impression that the C dory 25 (not sure about 23)--uses a 25" shaft--length is measured from the underside of the bracket to the top of the cavitation plate.

Agree with cmiii--you can use as short a shaft as 15", with a bracket--but 20" would be the best if you have a 20" transom. You can run an engine where the cavitation plate is above the bottom of the transom, but you will loose some effeciency, and it will not work well (if at all) in reverse. Best to get the prop below the bottom of the boat.
