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.

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

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.

Thanks again all. I plan on bumping it up to the last hole and seeing what it looks like then.

Any other tips would be great

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.
