Designed to protect and perform, the Blackfin™ Replacement Skeg is made from durable high-impact nylon composite featuring two tapered wings on each side for structural reinforcement and lift at every angle of engine trim. The Blackfin also features a sacrificial node on the bottom which limits the engine's skeg from plowing into underwater objects, and is shaped to turn the engine slightly on side impacts for more prop protection.

  • Durable, high-impact nylon composite construction
  • Tapered wings on each side for structural reinforcement and lift
  • Sacrificial node on the bottom limits engine's skeg from plowing into underwater objects

To determine the Blackfin model for your engine, measure from the front of the prop to the tip of the gear housing. Simply match this measurement to one of the Blackfin sizes listed below.
Note: The MerCruiser Alpha One when measured falls into the medium category, however it will require a small Blackfin.
