Review: vast improvement in performance - 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.
Review: Fit great, improved stability, gets on plane quicker, and the cavitation trail seems to be smaller. - Easy to install, perfect fit on my Verado 150, quality seems good, and judging by the other ones in the marina of the same brand that have been on for years in the Guam sun, the durability will be no problem.

### ⭐⭐⭐⭐⭐ vast improvement in performance
*by H***T on September 6, 2014*

### ⭐⭐⭐⭐⭐ Made a huge difference/improvement for Irish Wake.
*by P***Y on July 6, 2014*

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.
