So Far So Good

Bought the no-drill clamp set because the thought of drilling holes in my brand new motor was scary. Installation was simple. (The bolts for the drill installation are not the same) It seems to be VERY secure. The Orca Fin works GREAT. Hope the clamp stays secure for a long time.


exellent service and product worked as avertised

Tracy from Brookings OR

I purchased the dolfin and no drill clamp set, it was easy to install on my Yamaha 9.9, it is a well designed high quality product and provides positive control on my 24 foot Willie Raptor. I also have a TR1 gold installed on my kicker but have not used it since installing the dolfin. I am very satisfied with your product and would recommend this product to everyone.

Tracy, thank you for your comments. It's hard to get people to try something new. I appreciate people like you that are willing to take a chance. As you found out, we really do make a difference.
Trolling motor

Great product, works great, my TR1 slowed down

Orca Fin

Great product. Made a huge difference on my 24' pontoon.

Edward, I would love to get some photos of your pontoon and the fin installation. I know it's an imposition but I would really appreciate it. Richard Bogert
