Very good quality, screws are included
Just received it and checked for fit on my 25hp Yamaha 4 stroke. Screws are included. I just need to drill the holes and we'll be good to go. Very impressed by the quality and value. No need to spend $50 more.

Bolted this to my 40 hp Johnson. The boat gets up on a plane a little faster and I didn't lose anything on my top speed.

I put these on a 9.9 hp mercury but unfortunately they still didn't give quite enough lift to get my 11 ft zodiac up on plane, did help get it closer. Nothing wrong with the product, I do have it pretty loaded up when I'm in it so I'm sure more HP would fix it. No big loss to the wallet, they are still worth a try for yourself.

4.0 out of 5 stars Seasense Hydrofoil
Reviewed in the United States on July 22, 2013

I mounted this hydrofoil on a Johnson 88 special and went on perfectly. This engine is mounted on a 1994 Bayliner Capri 1800. This hydrofoil does require some drilling in order to be mounted on the lower unit. Before I mounted this on the engine I was getting 13 second hole shots which is more or less useless when trying to water ski. With the hydrofoil I am down to 8 seconds which is closer to where I want to be. Also, allows a lowered speed needed to hold planing from 22 MPH to 17 MPH.This product is no where near top of the line but for the price it is hard to go wrong. The downside to this hydrofoil is it did reduce my top speed from 34 MPH to 33 MPH.

These fins are a good deal for the money but, the lock nuts and bolts broke when I snugged them. Did not use a power tool only hand tools. As you can see in the pictures the bolt broke off in the nut. And they are thin to use. So I hade to go spend $10 addition for good stronger hardware.
If you buy these I would suggest buying better hardware than what they send.

Strong materials, and mine did include stainless steel hardware. I didn't notice a speed difference with my 75hp on my pontoon, but turning seems to produce less cavitation, so I'm happy.

5.0 out of 5 stars They WORK!!
Reviewed in Canada on August 25, 2022

Installed these on my Johnson 9.9 hp outboard, which I use on my small rigid hull inflatable. Without them, it was a real struggle trying to get the boat up onto a plane, even at maximum throttle. My wife & I had to crowd into the bow to try to get the boat to level onto a plane - it was awkward, and not very safe. When I did get onto a plane, the boat was skittish & hard to control.

With these foils installed, the boat comes up onto a plane at 2/3 throttle, with both of us seated comfortably - no gymnastics required. The boat is noticeably faster than before, is far more stable, and corners like it's on rails. Since I don't need full throttle anymore for cruising, fuel mileage should be greatly improved.

It's a win-win with these foils.

Really hard to drill holes in my Mercury 50HP 2 stroke. Drill is interfered by housing on lower unit . Had to buy a long drill bit to make the holes. Hoped it would lower the speed I could maintain plane and make it easier to get to plane. On a 16 ft legend boat. It did neither.
