Bracket Position

[1bayouboy]

Keep in mind that the brackets aren't hollow....they have structural supports inside.....stringers, etc....that support the load. I'm comptemplating doing a dual bracket...so that's going to be 800lbs of motor with a 26 inch setback.

That's an interesting point you make... I did not know that. That, however, goes to the structural rigidity of the bracket. My concern would be over the stresses on the transom while 800 lbs of motor is bouncing down the road 2 1/2 feet behind the transom.

Since I don't hear about transoms being torn off by brackets, it's must not be an issue.

Anyone ever do a bracket on an unmodified transom?

I'm doing one now . . . This is a NON issue. The Transom on my Seafari is 2.5" thick!! and the outer fiberglass skin alone on the boat is almost 1/2" thick. Neverending you're over analyzing this bracket thing. We'll never come close to pushing the limits of these boats with the type of boating/fishing we do. If you are thristy for more answers get a copy of elements of boat strength by David Gerr.

800lbs is nothing. Even the ones that are hollow are incredibly strong. I'd say Hermco is right on with the less material remark.


And if your next concern is fasteners . . . well I lifted the entire stern of my 20ft wellcraft off 5 inches off the trailer trying remove the powerhead and free ONE frozen 10mm bolt on a yamaha 200hp. 20 bolts holding a bracket on the back of a boat will never come apart.

Hey Bigshrimpin.....which one is that a picture of.....
I don't recognize the multiple facets.....

Of course I should put on my specs and read the Armstrong on the end....

That's me... Mr. Analysis Paralysis :-)

Thanks, and great picture. I did get my answers and I hope others learned from this as well. Again, thanks to all who contributed.

The D&D's look different. No open cavity at the transom surface. It's a solid plate across that point.

But a Hemco has more flotation. More expensive yes, but a top of the line product.

Look at the flotation chambers and their shape/size.
