Replacement Wood/ Auxillary Motor Bracker

Anyone know where to get replacement wood for an OMC 15 HP rated Auxillary Motor Bracket? Searched the web and all I could find was the motor mounts (All New). Maybe this is why is see guys with homemade replacements? Any help will be appreciated.

By the way. I'll be out later part of the week jigging and will let ya know. The winds have not been favorable, but it looks like SW's are coming with the warm temps. That will clean up and warm the water where we want it.

Good Luck and Good Fishing
