Delivery was timely. Good quality and easy to install

Great addition to my boat and my fishing!

The fin was easy to install and made controlling the boat much easier at the slower speeds during trolling. It even seems to have improved turning capabilities in high speed turns. Thank you Uncle Norm!


everything was great!!


Troll Plate Fin

Awesome trolling fin

I run an outboard autopilot (AP) in conjuction with my sonar unit for trolling on the great lakes. This fin does exactly what it is supposed to do: it reduces the motion of the motor back and forth in the water and keeps a true course via the AP.

Before I got an Uncle Norms fin, I watched as kicker motors on other boats would constantly be tracking back and forth in wide sweeps in order to keep the boat moving in a straight line; especially in chop and waves.

I have a 50 HP 4 stroke Honda BF50 on my C dory 16 Angler. With an Uncle Norm's fin, the Honda has very little movement back and forth through the water and the 50 maintains a true course. I'm not sure I can remember how I fished before I got and AP and an Uncle Norms fin to help the motor do it's job more efficiently.

Bravo Uncle Norm. Thanks for a great product.
