Anyone install a set of these?? If so ....what were the results. Also, what does a set of these usually cost?

Had them on my 36 Spectre for about a day. They nearly shook the boat apart. They seem to up set the water flow across the prop and it really upset the boat. Took us all day to find out that the rockers were to blame I really wish that they had worked cause they did a great job in changing the attitude of the boat at speeds below 100. Once the boat hit the higher hundreds the vibration was dangerous. Good luck OTTO

How did I do that????

I was involved in a project boat
a few years ago on a 29ft V.
Inserts were supplied before the
Boat was laid up in the mold.
The boat ran very well.
The rockers are under the boat
even with the bottom, Not added
to the transom.
You could call Paul at PSA Marine
In the Oakland Ca. Area, He ran
the Boat.

Also they were great about the return and very helpfull with advive on how to possibly make them work. Nice people and no problem with refunding me money with a smile. I would deal with them again for sure. OTTO

How about installed on a V-hull??

We cut the hook out of our hull and added a set. The rocker portion does work as they claim. Our max MPH didn’t increase much but we can carry the speed much better with a load up front. (open bow boat) or when full of fuel.

I believe list is $3,500

audaticity should chine in,I think the factory two guys had some good luck with theres,but him or treadwell would be the ones to ask.........

I think Tres Martin used them on the Glaidator that won the World and National F2.
