Rated 5 out of 5 by from Mercury Optimax 150 Easy to install, fits perfectly, boat planes out quickly and level, believe it adds speed to the boats top end. Made of strong, sturdy aluminum plate, great product! And made in the USA.

Rated 5 out of 5 by from The best bang for your buck The fins where relatively easy to install. The boat handled like a much bigger boat once the fins where on.The boat doesn't ride bow proud and slap and pound, but more rolling over the waves. Much more cost effective than hidrolic trim tabs.

Rated 5 out of 5 by from Awesome!! Put this on my 22' Sea Ray..I was expecting "some" improvement.. But I was sure suprised at such a difference right away.. The Stabilizer plate kept the bow down even coming out of the "hole" .. Also notice better steering/handling .. Would highly recommend this product.. Ordering from Overton's was a pleasant experience..quick and easy.

Rated 5 out of 5 by from No doubt the best available upgrade! This thing is great, my boat has never performed so well. Hole shots cannot even be measured in seconds. Porpoising and plowing is a thing of the past!

Rated 5 out of 5 by from Amazing Difference in Performance Remove your prop first, then install this. It's amazing how well it works. I have a 75 hp Mercury on an alumacraft. It used to take 3-5 seconds to get on plane. Now it takes less than 1 second. It's really helpful for pulling tubers or waterskiers. Takes off fast now! I should have ordered one last year like I was thinking of doing. It's well worth the [$].

Rated 4 out of 5 by from Somtimes you just need to take a chance This product worked great after I cut out the center more to fix my xs 300. It gives me a great hole shot. I could not seem to keep the nose down when I had people in the back seat due to running a high pitch prop. I guess most would not install this on a boat that runs over a 100mph but I would do it again tomorrow.

Rated 5 out of 5 by from Great Product Installed on 220 HP Stern Drive Deck Boat to improve planning/Handling. Installed in 3/4 hour. Used a right angle drill so I didn,t have to remove Prop. Very impressed with all results. Great hole shot. Improved stability. On plane time reduced by 25%. Top end speed increased by 15%. Smooth/quite in all catagories. No complaints at all. A great product at a great price.

Want to know if the edge will mount on my Volvo Penta Duoprop stern drive?  

Asked by: Rich
The Cobra The Edge Planing and Stabilizer Plate will work on the Volvo Penta SX outdrive. The best recommendation for most Volvo Pents Duoprop stern drives would be the Cobra The Edge Planing and Stabilizer Plate (Item # 34302) due to the tensile strength. If the Volvo Penta outdrive has the through the cavitation plate exhaust, then you will need The Voyager Pro (Item # 37029).
