Outboard bracket set back?
« on: January 30, 2013, 10:06:10 PM »
I have a '75 246 CCC that I will be enclosing the transom and installing a bracket. My question is what is a good setback lenth for that size boat? Or does it even matter? I can get a good deal on a 18 inch set back but I dont know if that is far enough back for the size of my boat. Anyone with knowledge in this please let me know what you think and also anything else that i might need to know before buying one and installing it. Thank you. I will be putting a 250 hp outobard on it if that makes a difference for anything.

I'd go with a 30" setback. Checkout Armstrong Nauical Products, you can get all the information you need from them.

24" to 30", as Nando stated.  His 30" Armstrong makes for a GREAT platform (swim, dive, piss, fight a fish) that becomes a truly useful part of the boat.  Given that you'll have engine rigging and steering hoses encroaching into that space...the bigger the better!

Besides, Nando's dog, Guiness, HAS to have that room!  Ingress/egress, you know?! :thumleft:  :thumleft:

And this would be Guiness...

My B Bracket platform was 26" on my 222 CCP.
Performed excellent and added needed transom space.

Good luck.

Thank you, I get what you guys are saying about the extra space and totally agree. I will probably go with 26", I just wanted to make sure that there wasnt a certain set back distance in relation to the boats size.

have you thought about a porta-bracket?  I think they have a 26" set back.

Yeah, they do Scott, but with swim platforms would come in around $3300, plus you have to locate and rig the pump, the hoses, the drain on the batt...

I think an Armstrong or Stainless Marine single engine bracket would be the deal here...

I ahve been researching the same.

Minimum offset should be space needed to fully up trim your motor without hitting transom.

Here are the cheapest brackets I have seen.

I actually contacted A&J for a quote on a 26 inch set back and will def. be going with them for the price. They quoted me for a standard bracket and a flotation bracket. The flotation bracket was $100 more. Does anyone know what the difference is between the two types? and for the cost would it be worth it to go with the flotation style?

Before you order anything!!

I have been installing brackets from the 2 biggest in the business, Armstrong and Stainless marine for a LONG time now, and have never come across, nor was it mentioned,...flotation model.  So do yourselves a favor, contact these companies and have them explain to you just what exactly the "flotation" model consists of.  Do they just fill them with foam?  Can they prove that their brackets improve bouyancy?


Sounds like a bunch of BS to me...

As it was explained to me 17 years ago.

The "added" floatation results from the air trapped in the engine mounting area. My B Bracket was solid across the transom and the "cube" of air trapped inside added some floatation to offset the weight of the motor. There was no foam inside but I doubt it would "float" if you dropped it in the water. Still, I never tried and no one said it would only that the air pocket created in the mounting section would offset some of the weight.

Whatever.

Without a doubt if the enclosed area of the bracket is below the waterline and it displaces water it will provide flotation as long as the volume of the area displaced weighs less then 64 lbs per cubic foot (salt water).  So if the enclosed area weighs say 20 lbs and it displaces two cubic feet of water than it will provide 108 lbs of bouncy.
