why did you post this 3 times?? Just go to the others and hit delete this post, and stay with one.

The Bracket is fine. You need to mount the cavatation plate even with the bottom of the boat.

But there is a rule I did not follow when I did mine, for every 12" back you go, you want to raise the motor 1" i believe?

I dont know if it is an Armstrong bracket but it has same configuration as mine. On a 30" approx set back bracket you want the cavitation plate to be three inches above a line straight back (keel line) from the hull. According to Armstrong techs that is considered ideal. With a caveat added, that is some motors are much heavier than others and you might have to adjust that height up or down an inch or so to compensate or you will be dunking your motor too much. Call Armstrong and talk with their techs, nice people and will be very helpful ;)

Not sure what you mean bud ???

if you get a shorter bracket, and get a V6 motor you will not have room to lift the motor up high anough.

And you want it all the way up if you are moored, and anough to get it up a ramp with out hitting!!

If its not to much to ask can I see some of brackets that you guys have out there

I believe a 30 inch setback is pretty standard and should allow room for any v6 to be fully raised.

However, I don't think the extra 3 inches is gonna hurt you. *I'd leave it alone and install it as it is...

Also pay attention to whether you have a 20 or 25 inch shaft motor. *That will make a difference in figuring everything out.

I hope to be dealing with these same questions before long...

Oh yeah, if you'd like to know more and see more do a search on the word bracket. Also go to the gallery section of the website and take a look. You'll see a good number of brackets.
