Congrats BA! In the end, I couldn't pull the trigger on it myself because I have too many other things to worry about at the moment. Good luck with her! Btw, you aren't from South Louisiana are you?

Thanks,
No, I live in Marietta, GA and not real happy about it. I would like to get back to the coast. I am ready to pick it up and get started.

A 200hp 500lb(with the prop and oil) Yam sitting 30" behind the transom is way more than the boat was designed for. 500lbs 30" back is the same as 700lbs bolted to the transom. You'd be better off with twin V4 Johnson 115's bolted to the real transom. It would float higher. Most older boats are not designed for a bracketed outboards. Especially with the weight gains new engines have seen. In 72' the nastiest thing around was a 125hp OMC V4 that weighed 300lbs.

I think I just talked my self into something............

You might want to talk to Don in ft Pierce at hermco. If I remeber correctly he was planning on putting a 200 on a bracket with his 20.

I am not sure of the buoyancy of the single for the 20, but I would think it be in the neighborhood of 350lbs +- at the water line, at a guess. At that the weight of a 200 would be fine.
I understand well what Dunk is saying, it's like haveing a 3.4 liter merc, weighing 575lbs sitting on a Gill bracket with no floatation....Not recommended! Though the boat didn't sit as low in the stern as thought.
I know the Don's brackets have 800lbs of buoyancy for a twin, 500 for a single for the 23's and as I said I am just guessing at the 20. But even if it was 250lbs buoyancy it would still work fine.
How's that for a fine Finster editorial!

In the HermCo's literature for the Seamark (Potter bracket)
the Single version is listed as 6' wide (25" shaft) and has a buoyancy of 420 lbs
the Twin version as 7'2" wide with a buoyancy of 890 lbs

These are the only two models listed in the copy I have.
Isn't the Single version the model that has been used on the restores of the 20's on HermCo's site?? I didn’t realize there was one manufactured specifically for the 20.

Hermco did this renovation and installed these brackets on Bill Potter's personal boat, a 20' Seafari.

I had to stop clicking on Hermco site about a year ago, my keyboard was filling up with drool over that blue Seafari!!

That's one sweet Seafari!! [img]/images/graemlins/smile.gif[/img]
