Orca Performance Fin
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.

As advertised. I was looking to improve low speed stability and the Orca Fin delivered. Upon receiving my product I decided to bolt it on rather than use the clamp set. I contacted Uncle Norm's about returning the clamp set and they said no problem and I was refunded my full purchase price. Great company to do business with, great products, just as advertised.
Took my boat out for the fist time after installing the orca tail and I have to say, it’s the single most fantastic game changer in the world! Handling is phenomenal at low speeds, and idle with the boat just gliding in neutral, it can still be controlled! This thing is just AMAZING!!!!!!!
Haven't installed yet, am going to use on the Nehalem Bay, will let you know when I get the boat I. The water later on.
Installed Orca fin on 21ft pleasure boat, worked great. Took all the bow wandering out at low idle speeds, no more fighting the streering wheel to hold coarse at 2 -5 MP. Had the hydrofin on boat and after a year it cracked so i went with the Orca fin from Uncle Tom and it works just as well getting boat on plane faster, grate for skiing and tubing, much tighter turns at any speed. Works in reverse, hardly know its there.
Would highly recommend if you are haveing issues with bow wandering or getting the hole shot.
Love it, little pricey but worth it. Purchased no drill install kit.
Fit like a glove...pre-drilled holes fit perfectly with pre-existing holes on cav plate...drilled two others no problem and worked lerfectly today...steering benefited and hole shot was effortless.
