Stainless marine o\b bracket

[kmoose]

Tabs are the main issue that I see. Bottom paint can take a few mph out of it too. My bracket is high but yours seem especially high so that is likely causing you to run the tabs down and motor tucked in which creates the turbulence interfering with the prop as well as extra drag.

It not going to be an easy fix but its totally fixable. Pull the motor, bracket and tabs. I don't know if those are scuppers on the outside but that is where the tabs need to be so new tab plate brackets will need to be modified (cut) to go around the scuppers. Fill and patch all holes, patch paint, drill and remount. It's a big job but nothing that couldn't be done in a week with about $1,700 in supplies including new tabs and bolts. The difference in performance would be priceless.
