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: Works good, lasts long time. - Works great. Around 200/300 rpm drop to get on plain. 18.5 stabicraft 115hp Yamaha. Does increase spray a bit. Otherwise, the product is straightforward. Trimmed out. 3250/3400rpm. 17 mph avg. 3.2 /3.3 gph. 19 pitch prop.

## Questions & Answers

**Q: I have a Mariner 30 about 20 years old, on a 17 bass boat,  will it fit?**
A: these are universal fit by size range, with your 30 hp motor you probably want the SE 200 as its 8 to 40 hp

**Q: few pounds weighs about the product?**
A: Polymer composite - very light, yet strong.

**Q: Will it fit a 135hp Mercury I/O ?**
A: Thanks for your interest in our high performance hydrofoils.
Either our Sport Marine Technologies, Inc. SE Sport 300 or SE Sport 400 (optional drill free) will work great for your boat.

**Q: How far past the cavitation plate does this stick out? In the full up position I only have about 4 inches before hitting the extended swim platform.**
A: Five and 1/2" on my 40 hp merc. EFI.  It extends 6 3/8" from the U-curve on the hydrofoil to the back.
