Despite the poor reviews, I bought this because I did not want to drill holes in my ventilation plate. I called the mfg regarding the reviewers who lost the device. I was told that if I followed the instructions and used Loc-Tite and a longer bolt if necessary, the gadget would stay on. The results were spectacular. The hole shot was much improved as was turning. It made the boat (19' Mariah w/ 260 hp Merc)usable for skiing and towing whereas it really was bad before.
I liked the results so much I ordered another for my wife's 22' pontoon boat w/ a 90 hp Merc 4 stroke. The boat handles much better and is quieter. Also almost no wake. Top end increased by 2-3 mph on the pontoon boat but decreased on the Mariah by 5-6 mph. I really don't care about the top speed but I did care about the hole shot and the handling.

I liked the idea of not drilling holes in cavity plate. Foil went on easy and did all that it claims. Took boat out to winterize and noticed it was cracked in 3 areas. Foil is held on by dropping gearcase anode then sliding foil over cavity plate then you rebolt anode. Plastic that is used to secure to anode is weak and doesn't hold up to pressure. Apears other purchasers on other web sites lost the foil,and anode plate during use. Some had prop damage.

        Comments about StingRay Sting Ray XRIII Senior Hydrofoil Stabilizer:

        I added the hydroil to my 2007 stingray 210cs, works like a dream, my boat used to porpoise like crazy you couldn't even sit down when driving the bow would go so high, now it gets on plane seamlessly and the bow stays nice and low and handles excellent, mine is a mercruiser 4.3 with alpha 1, you will need to get a stainless steel Allen bolt at least a 1/2 inch longer to make it correct, Allen head because you will never get a socket threw the hole on the alpha 1 outdrive, that was the only downfall tracking that bolt down, but I would definetly buy this agian, very satisfied

            Comments about StingRay Sting Ray XRIII Senior Hydrofoil Stabilizer:

            It makes the boat ride smoother,comes up on plane easier and uses less power.
            I have a 19 foot Sail Fish with a 115 Yamaha and it would porpoise real easy. You had to have the plane set just exactly right. With the StingRay stabilizer the bow of the boat stays down, rides smoother and the plane is not so touchy.
            Installation is easy.
            The boat backs up differently but not a problem once you get used to it.
            All in all I would recommend it if you want you boat to perform better.

                1st thing I put on our 18' Crestliner Mirage w/150 Merc Optimax back in 2007. You'll need to change your prop or it will drag your RPM's down and you'll loose top end. Went from stock 23 pitch prop down to a 17 stainless steel for recommended engine RPM range. Top end went from 34mph to 42mph with 2 people, gear and 40 gallons of gas. Trolls now at 1.5MPH The boat will actually turn now without capitating! Fuel ecomony is much better and I have over 5 years and 300 hours on this product with no issues!

                      I have a Crownline 220EX with a Mercruiser 5.0 MPI 270HP Bravo 3 outdrive. I operate the boat on Big Bear lake in So California. It is at 6,800 feet and my boat struggles to get on plane with more than 2 people in it. Will this or your other products fit and what performance should I expect?

                        Hello Bill,

                        Yes. The Sting Ray XRIII Senior will fit on your outdrive. It will help with getting on plane quicker than you are know. The other suggestion would be to go down in pitch of your prop. This too will increase your hole shot.

                        The website is: http://www.marine-dynamics.com/install.html
                        These are the instructions there:
                        Both the StingRay™ XPI and XPII Hydrofoil Stabilizers and StingRay Junior™ models are easy to install. All the hardware you need is included: four bolts, four self-locking nuts, four stainless steel washers, and four
                        rubber washers. Simply drill four (4) quarter-inch holes in the cavitation plate on the lower drive unit and bolt the StingRay™ on.

                        Pre-drilled holes in the StingRay™ serve as a guide for drilling the four holes. Placing the StingRay™ on top of the cavitation plate, insert the bolts from the bottom up. Place the rubber washers on the bottom side and the stainless steel washers between the top of the unit and the self-locking nuts. Use a socket wrench to tighten the nuts.
