Fin estabilizadora Sport 300 40 – 350 HP

I have a 1979 Orrion Oriole 19V, she's the only one in existence still on the water, she's in mint condition, and I just rebuilt the lower unit. She has an OMC 260 with an upgraded Holley Carb, and MSD HEI ignition so she's a little rear end heavy. I added this hydrofoil during the rebuild figuring I'd at least reduce some cavitation and get a little more stability pulling skiers and tubes. Boy did i ever get that, and more. My boat now plains out at 16mph on average, i can get her to plain at 12mph in dead calm water. I also noticed almost no bow bouncing/porpoising, and the steering wasn't effected at all and she turned just as tight as ever which is one of my favorite things about the old boat. There was also a marked improvement in fuel economy and speed. 54mph at 3000rpm in light chop. The engine stayed nice and cool the whole time, and the hole shot is amazing. It's like i put a completely different drive on her. A must buy for anyone running an OMC Stringer or Merc Alpha 1, and would be an added improvement for any outdrive, even a Bravo 3. If you have a sporty boat, pull skiers tubes wake boards etc, just like good fuel economy lower plain speed and better hole shot, you would be an idiot not to buy this product. It took me 5 minutes to install too. My only recommendation to the manufacturer is to provide longer bolts, i put different bolts on mine because my old cavitation plate was super thick. Other than that, excellent product, it made a 35 year old boat out perform brand new boats with more power.

Worked like a dream! Best investment I’ve purchased.

Loved the performance and it was easy to install but when it came off at the lake I almost knew it immediately but it was too late! I ordered another but will drill and bolt this one on!!

Very good working product, get me on plain really quick

I installed the SE Sport 300 Hydrofoil on my 24' long 2008 Glastron DX 235 deck boat. I am running a 19 pitch 16' Mercury Vengeance stainless steel prop from an SEI 116 sterndrive. The entire package is powered by a 250hp Mercruiser 5.0 EFI. I used the Sport Clip since I didn't want to drill into my cavitation plate. I had to modify the foil slightly by opening the yoke portion with a grinder. The manufacturer expects this in some applications and states that it does not void the warranty.Now to the performance; This is a heavy boat that I believe was underpowered from the factory. That being said, the SE Sport 300 made all 5500 lbs of boat, equipment and passengers JUMP out of the water from the hole. Within 4 seconds, Irish Wake was on plane and there was no hint of RPM letoff once there. I can stay on plane all the way down to 14 or 15 MPH (GPS) when I had to be at 19-20 mph. And once on plane the porpoising is nearly eliminated. I also can use my engine trim with the foil when previously it was irrelevant. I installed the SEI Summit Drive Shower at the same time and had to do some creative engineering but all is secure and functional. The manufactures boast a four point securing technology for their clip. I took the stainless steel tab that secures to the annode mount and is supposed to have a small amount sticking aft, hidden by the foil, and bent it around the rear of the foil. So now it has a five point security system.Buy this if you want a meaningful, easy shade tree mod for your 40-300hp rig. Buy the drive shower too. You won't be disappointed.

I decided to use the no-drill option and bought the Sport Clip together with the SE300. The company has two YouTube videos on installation of the sport clip so I knew it was going to take some time. I spent about an hour installing that part to make sure I got everything absolutely perfectly correct. The YouTube videos do a wonderful job explaining step-by-step what has to be done.Installing the hydrofoil itself was a breeze as the only thing required is to install four washers and tighten down four locking nuts. The finished installation is extremely sturdy and rigid.On our Lowe 21 foot tritoon with 115 hp motor The hydrofoil helps get the boat on plane quickly even when the boat is loaded down with six adults and four children. It was a struggle to make that happen before but now it is done easily.I tried two other hydrofoils before this one and felt that their installation was far less than ideal. One of them used only the trim tab to secure the hydrofoil and the other used a different method but neither was as secure as the SE 300 with Sport Clip.I certainly haven’t seen and tried every hydrofoil on the market but this one is extremely well designed and very well engineered. As long as you take your time and follow the YouTube videos you should have no trouble installing this on your boat.

I must say WOW. Boat planes easier now and handles better. Wish I had got this sooner. Haven't tested speed yet though.

The item arrived with a large slice in the packaging. That should have been noticed when packaged, so I sent it back. The hydrofoil will not fit a Mercury Derado 175 as that motor has a secondary cavitation plate above the main that make it impossible to drill straight up and down, meaning only the rear screws can be mounted, not all four. If your motor does not have an unobstructed view for all 4 screws holes to be drilled, you may have to do what I did and order a no-drill SE 400. I was still able to drill 2 holes with the no-drill SE 400 to insure the hydrofoil will not fall off as noted in previous reviews.
