Hermco bracket engine height
 

Hey guys just looking for some feedback I installed a bracket on my 23 last year and this was the first run. Engine looks low to me but I'm not sure. This was a loaded bot full 50 gal livewell and 4 people I usually fish with me and other person. I have one hole left to raise it up.

The pictures arnt great but maybe someone can give me an idea if I'm in the neighborhood or not.

Thanks
Jason

Too low to me. Bushwhacker had a good way to see the AV plate-black electrical tape on the top to see it right above the water.

See all the spray?
Way too low.

Thank you I had a feeling it was way to low. I hope the last hole gets me high enough I don't want to put a jack plate on it.

Do us all a favor and take pics on the trailer with an azz shot...
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.

Although my experience with a Hermco bracket is on a 20, I suspect you may need a jack plate! Check out post #4 in this old thread about motor height.

Are you running on plane in that pic or plowing? At Don's recommend mounting height with Yam 300 in the bottom hole I'm right on on my 23

This was taken on plane.


Bushwhacker any recommendation on a jack plate I would assume the least set back and greatest height adjustment.

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 raising it a hole doesn't do it, then make sure you have a stern lifting 4 blade prop and a fin. (I wasn't sure if you had these already). Those you can do easily before a jack plate.

Thanks I have a fin but it wasn't installed at the time of this run I will put it on and see what she looks like, any good prop brands to look for? I am sure i can find something on here. I'm itching to get this dialed in our Bluefin bite is starting to finally get going here in NE. Just for fun here's a small Giant 83'' coming over the rail last season.

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!!

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.
