Transom Retro

[Mr. Sandman]

It is a PIA and somewhat costly job but it will work and as far as performance goes..it should increase. Generally, outboard propeller efficiency increases a little bit to a sweet spot a couple feet aft of the transom. I don't know the exact sweet spot (a bracket manufacturer might though) but you're headed in the right direction.

Instead of doing all that...just buy a boat made to take the kind seas you plan to fish. If your feet are getting wet..that is a hint.

I would not count on a bracket increasing performance at all. It depends on the vessel as well as the running surface. Backing down or stemming the tide may also become more difficult. I specifically looked for boats without a bracket due to my style of fishing.
