I don't know what size tabs you have but 12"x 12" Bennett's seem to be the most popular size for the 23'. Bennett does make different size actuators, so depending on your bracket type and at what height the platform is, will determine what size actuator would fit best. I have the SeaMark (Potter) bracket. I got the 10" actuator from Bennett. It was the smallest they make and I still had to notch the platform on the bracket. I think the Lenco brand trim tabs will fit under most brackets without modification. If you intend to utilize the Bennetts, I would contact Tom Mcgow at Bennett Marine for his advise.
