Package Contents

  • 1 x Hydrofoil Stabilizer
  • 4 x Sets of Stainless Steel Mounting Hardware (bolts, nuts, washers)
  • 1 x Drill bit (6.5mm)
  • 1 x Installation Instructions

Installation Guide

  1. Disconnect the battery and ensure the engine is fully tilted up and secured.
  2. Position the hydrofoil on the cavitation plate, ensuring it is centered and does not interfere with the propeller's movement.
  3. Mark the drilling locations on the cavitation plate using the holes in the hydrofoil as a template.
  4. Remove the hydrofoil and carefully drill the marked holes using the included 6.5mm drill bit.
  5. Place the hydrofoil back onto the cavitation plate, aligning the holes.
  6. Insert the stainless steel bolts from the top and secure them with washers and nuts from the bottom.
  7. Tighten the hardware evenly until the hydrofoil is firmly secured. Do not overtighten, as this can damage the cavitation plate.
  8. Lower the engine and visually inspect for proper clearance before reconnecting the battery.

Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my engine?
A: This hydrofoil is a universal fit for most outboard motors and stern drives from 5 to 150 HP. It is not compatible with specific models like Volvo Penta 280/290 outdrives or BMW outdrives on engines over 50 HP. Always measure your cavitation plate and compare it to the product dimensions (10-1/4" H x 8-1/4" W) to ensure proper clearance.

Q: Will I need to drill holes in my engine's cavitation plate?
A: Yes, this is a bolt-on installation that requires drilling four holes in the cavitation plate. The kit includes the necessary stainless steel hardware and a 6.5mm drill bit for your convenience.

Q: What are the signs my boat could benefit from a hydrofoil?
A: If your boat struggles with slow planing, porpoising (the bow bouncing up and down), or cavitation (propeller losing its grip on the water), a hydrofoil can often improve performance. It helps lift the stern, allowing the boat to get on plane faster at lower speeds and improving stability.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

One of my favorite purchases ever.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
So I bought this backlight a few months ago and it's been one of my favorite purchases I ever made on Amazon. Honestly, once you start using the backlight, it's so hard to go back. It makes TV and games just so much more immersive, especially when there are bright scenes and the lights flash, or when there are dark scenes and it just goes completely black. The setup is really easy but it does take some precision to get it right the first time and to keep it working for a long time. And sometimes the things that stick the wires to the back of the TV do like to fall off. Although that may be a consequence of how my TV is built. I think it looks best in a darker room where there's less space for the light to go away, especially when the TV is against a wall. But that's how I use it, and it's been just an amazing experience. The app functionality is also pretty good, although I don't use it as much these days and I just keep it in TV syncing mode. The lights can get really bright, so if you want to, you can use it as a separate ambient lighting for your room. Although personally, I think that's too much effort and I just use my lamp. Coming from someone who uses his TV a lot, if you're on the fence, just get it

Movie lighting must have.
Size: 11.8FT for 55''-65'' TV, Size: 11.8FT for 55''-65'' TV
This is exactly what it was in the listing. It was very easy to install they stick to the back of the tv very well. The lights strip is good quality and they wont fall off the tv even from the heat.. The app is easy to use. Will say there are a lot of options to control it from the app. Once the control box is behind the tv your not going to be reaching back there to turn it off and on. I have mine connected to Alexa and Google so i can control them with my voice. They look great for watching movies even in a somewhat lit room. Be mindful of the camera on the top of the tv I did have to calibrate it 7 times cause it wasn't picking up all the corners and i accidentally hit the camera while walking around if your tv is on the wall you have nothing to worry about unless you have my first issue of it not catching the corners properly. The little orange squares don't stick too well especially since i had to do this several times. Even tried it without the squares and still had problems. The video was recorded after the second time of calibrating it. The problem comes when you try to get the hue right. Everything white makes the lights turn red so i had to mess with the saturation and the white balance on color calibration feature on the app to get it as close as possible to the white on the tv and its still something i have to adjust ever time i watch something.(Shown in the second picture)

Amazing!
Size: 11.8FT for 55''-65'' TV
I absolutely love these lights. I will never go back to no lights again haha. Perfect for movies, shows, video games. Also super easy to get it installed. The only issue we ran into a little bit was the app and trying to get the tv shape and layout registered.

Effective & Attractive with Wireless Charging
Color: Blue, Color: Blue
This "valet" organizer, which is the first time I've heard that term for a product like this, is nearly perfect. For me, it checks all of the boxes and in a perfect world, I would have opted for a smaller piece with only three compartments for mobile, wallet, and keys. It's well made and quite attractive, especially the blue (favorite color, so I'm biased). The only feature I'm not a fan of is how the removeable, wireless charging pad was implemented, which sits up on a small lip at a slight incline. However, I'm not complaining one bit as the wireless charging is great, and it's a differentiator that determines the value of the piece. I would have preferred the pad be built into the piece, however the angle of it does make it easy to grab opposed to using your finger(s) to pry it up.
