Motor Mounting Bracket. Our transom system allows for quick and easy removal in the case of a tough hide. It can be used with the upright towards the stern for an outboard or trolling motor or it can be turned around for use with a mud motor (bringing more weight forward for an evenly balanced boat). Constructed of black anodized aluminum it is lightweight, durable, and extremely rigid. The transom is rated for a 7.5 HP and will fit the Fatback 7.5 or Fatboy DP layout boats.
