No-Drill Clamp Set

Orca Sea Ray 185 Sport Ski Boat

Very impressed!!! My Sea Ray 185 Sport with 3.0L MerCruiser would wander back and forth at slower speeds like I was drunk. It was always a handful to get into our boatslip or gas pump. Now with the ORCA fin it holds straight as an arrow at slow speeds, no loss in top speed or max RPM. At tubing speed it carves harder and the hole shot seems quicker too. Basically there is zero time to hit plane... it just comes out straight from go.

Jesse, Thanks for the review. Your experience is like so many others. The fin is simple but it works really well. I would love to get photos. Those that were attached would not open.

At this point I have not been able to put item into service,, but I will say that the customer service is top shelf. I got my no dophin fin. but was missing the self adhesive rubber strips.. I contacted the company and they had it shipped immediately and I recv'd it within a couple days.. I am very satisfied with their service and have complete faith in that this product will do everything it is supposed to do,, to the point I have a friend that is a charter Capt,, and is now waiting to see my results.. tks again and for your concern of how things went with one of your customers.. Follow up is the mark of a successful entity..

Excellent no holes bracket

Attached with no problems.

Juan, I would like to know what kind of motor you installed it on and I would love to have a photo or two if you could send them to me. Let me know how it works for you.
