Ive used a number of store bought brackets and hated them all. The ones that fold up wobble so much your trolling motors flopping around like its going to fall off fixed ones that are not designed right for your boat also suck. I gave up and made my own. If you can get the Ob a foot or more behind the boat it will not only push your boat better you’ll troll at lower RPMs turn quicker and use less fuel. The down side is you’ll need a extension handle and you’ll have lean out to shift it unless you have controls or a lever extension of some kind. Im sorry I don’t have pictures but mine became a full on swim deck extension I rented an aluminum spool gun welder and made a shelf for about what a decent store bought unit ran. Mind you today I own a tig and mig for aluminum. It would be simple to make a bracket on your own aluminum cuts with a chop saw and us pretty easy to work with.
I agree with you 100%....except.....
Years ago I bought an OMC retractable bracket that came with a gas cylinder to ease it up and down. No wobbling or flopping. My 9.9 has been mounted on it for 34 years now, Summer, Winter, on the highway and in the garage. Awesome product. Sadly they don't make them any more after BRP bought them out.
A few years ago I found one on Ebay, brand new never used. I bought it up in an auction frenzy, paid double what I paid the the new one years before. Anyway, now I got a spare in case I need one in the future.
Without that I guess I would build one myself as well.
