Amazing planing with this product
by Gregory from Lisle, Illinois on July 04, 2016
I have a 1999 19.5' Sea Ray Bowrider without the stabilizer, it took 12+ seconds to plane. After installing it, it planes in a couple of seconds even with heavy tubers or skiers. Great product!

worth the money
by Ian from Plum Coulee, Manitoba on April 23, 2015
Helps my heavy boat jump out of the water. Seems to help keep the ride a little smoother, but can't prove it. I was sceptical at first and some reviews say they don't make a difference, but I notice a huge difference! I also believe you have to set your boat up correctly for everything to function correctly. The installation was easy, I bolted the 2 front holes through the motor to insure I don't loose the hydrofoil. Love the xr111.

Bad product
by Jonathan from Cross Lanes, West Virginia on June 11, 2013
Does not work as advertised. Installed the product and used for about fifteen minutes. Noticed the motor labor-ing and water spraying everywhere, boat was running about five mile an hour slower. . Un-installed the product an got my speed back. Of course iboats has it in the fine print if product is opened and installed they won't honor a return. Very disappointed in the whole deal. Would not recommend this product to no one.

use caution,and longer bolt
by Alan from Boonville, Indiana on September 14, 2012
I had to make a longer trim tab bolt,the stock bolt was not long enough. I tried it there way and it fell off. I lost the spacer and my trim tab.But the hydrofoil floats so i was able to find it. So i went and got a piece of aluminum and custom made a new spacer, went and bought a new trim tab, went to a bolt and nut store found a longer stainless steel bolt but the head was too big. so i cut a slot in it and was able to use a screw driver to tighten it ,because you cant get a socket on it ,because the factory bolt was a specialty bolt that is impossible to find in a longer length. So after all that bs i got it to stay on and work.

worked great
by Michael from Milton, Florida on June 18, 2016
Installed properly and it worked great and held up. Did what I hoped it would. It rained a couple of days before I took it out , and I noticed water had gotten under the edges of the label medallion and it was lifting on the edges as some have said . I peeled it off and replaced it with a good contact cement and it stayed on tight for the test run. I used Loctite on the lock washers and everything stayed together and remained tight. So far I am pleased with the results.

Poor fit
by Donald from Albany, Georgia on June 01, 2016
Bought this hydrofoil because it stated "no drilling" and was supposed to be an easy install. I have a 2002 Yamaha 90 2 stroke, the color matched and looked good beside it. I removed the trim tab per installation instructions. When placing the hydrofoil on, it wouldn't fit all the way on. I made the decision to trim it in the V section so it would fit. The trim tab is the only thing holding the hydrofoil on. Well, two problems, One is the fit isn't flush, and Two is the bolt will only have two or three threads holding it on. Bolt is too short. Cannot trust that type of set up, so I removed it. I have altered the Hydrofoil so that it is not returnable. Lesson learned. Easy does not always mean correct fit.

StingRay Sr. XRlll Hydrofoil Stablizer
by Philip from Portland, Oregon on August 26, 2015
This product preformed as stated. The holeshot was quicker and the handling of the boat has improved. I did not see an increase in top speed but my boat dose stay on plane at lower speeds. I have not used it enough to determine any other benefits to having the hydrofoil on my motor but I am sure that I will notice more improvements.
