Orca Performance Fin Out Of Specification

Uncle Norm's Marine Products

  • $ 18900

Add No-Drill Clamp set? ($69)

These fins will work just fine, they were not made correctly to the drawings though.  They are 2" wider at the top and the sides are 1" shorter.  These discounted fins are only available for a short time.  Once they're gone, they're gone.

The Orca-Performance Fin triples the effective rudder area providing a tighter turn radius and sharp crisp directional control at any speed. The larger surface area of the Orca-Performance Fin blocks cavation better than hydrofoils while adding the benefit of enhanced slow speed maneuvering and heading control. The Orca-Performance Fin installs in minutes without drilling using the 45M-Clamp kit or bolt directly to the cavitation plate using included hardware. The Orca fin is usually mounted with the fins down but may be installed fins up without modification if you desire less aggressive control. Used and tested on fishing boats, runabouts, pontoon boats, cruisers, ski boats and bass boats since 2002.

      Great Fins !

      I finally got to use these fins after a short illness. I found them to be a great purchase. My wife was very skeptical at first and did not believe they would make the handling of our boat better. She found out that they make the steering and control better with the fins on the boat. We both love them Thank You !!!

      Martin, what type of boat do you have? I'd love to have you post a photo of it. - Regards, Richard Bogert
