Yes, you generally want to minimize setback to avoid having a boat CG that's too far aft! Vance Mfg. makes some inexpensive manual jackplates with 3 and 4 inch setback. The JPL4300 model with 4" lift got my motor up where it needs to be.

Jason. I have just completed the same setup. 23 with single Hermco bracket. Trying to work mine out as well. I am on the Cape to in Sandwich. Did you end up putting a jack plate on. What engine are you running. Maybe we could chat on the phone. If so PM and I will shoot you my number meet.
Thanks Tyler

Sorry just saw this. I didn't put the jack plate on yet I went up to the last hole and i am right on the edge of where I need to be.

Man that sure looks low!!

I just got through mounting a Hermco on Jr's 23 Sceptre with a new
25" Suzuki 300 HP !:cool:

We are dead nuts with the mounting after his sea trial.
One hole up on the bracket. 5.75 inches from the bottom
of the boat to the plate..... ;)

Simple geometry.

If you mount it per NoBones recommendation, you may not need a jack plate.
This JPL4300 Vance Mfg. Jackplate has the least setback (3")of anything I've seen, but it's only rated for 225 hp. It's 4" height increase was all I needed.

Don't know what motor you have, but the BRP Cyclone is an excellent 4B prop with lots of stern lift. The BRP Rebel is also a very good 3B stern lifting prop with lots of blade area and cupping. Pic below shows what you should see up on plane if your height is right.

Thank you! I added a jack plate and I think I am in the ball park now. Need to fine tune it. First run had the plate just about above the water boat run completely different now more speed and better WOT RPMs. I can get on plane at much lower speed too.

Thank you all for the help I will keep you posted after I dial it in.
