Not sure what you mean. Are you mounting the top of the bracket at 22 1/4" down front the top of the transom on the boat?
My main concern is that the brackets transom (back of bracket) is 25 inches tall and you are mounting a motor with a 25 inch shaft. Most brackets have a transom height that is shorter then the shaft length of the motor to allow for adjustment of the motor up or down. Your anticavitation plate will be at the same level of the bottom of the keel of the bracket at your motors lowest mounting point. If you have to move the engine up (most of us do) then your anticavitation plate will be obstructed by the bracket. The way you have your bracket constructed you you will have to place your bracket in exactly the right place because you will have no vertical adjustment of the motor once it's mounted. If you go with a 30 inch shaft motor you will have more room for vertical adjustment of the motor. The rule of thumb is that the motor needs to be raised 1" for every foot of set back however more often then not you will raise it a little higher then that.
