Cavatation plate Honda 9.9 hp

[rapala]

Have a Honda 9.9 hp kicker, when I bought the Honda 2001 it had a 6" extension so the prop was lower.  Wondering what height should the cavitation  plate be  in relation to bottom of boat.  I would like to take extension off.  All I would have to do is buy a shorter shaft.  I have a manual motor lift which raises it about 6", not enough because prop is in water when underway.  Any ideas would help.

The cavitation plate should be even or close to the bottom of the hull. If in fact, you do have an extension kit on it now, it might also just have an extension on the driveshaft. You may not need to buy anything.

As deep in the water as possible so you avoid coming out of the water and spinning air on every wave.  You do not have to have it even with the transom because the kicker is not going to put the boat on plane.
