Installation Guide

  1. Safety First: Ensure the engine is off and the boat is securely positioned on a trailer or lift. Disconnect the battery as a precaution.
  2. Position the Hydrofoil: Place the hydrofoil stabilizer onto the anti-ventilation plate of the outboard motor or stern drive. Center it and ensure it is straight.
  3. Mark Drill Holes: Use a marker or scribe to mark the four drill hole locations on the anti-ventilation plate through the mounting holes of the hydrofoil.
  4. Drill the Holes: Remove the hydrofoil and carefully drill the four marked holes. Use a drill bit appropriate for the material of your anti-ventilation plate.
  5. Attach the Hydrofoil: Position the rubber washers (if included) and the hydrofoil. Insert the stainless steel bolts from the top and secure them with the nuts from the bottom.
  6. Tighten Securely: Tighten all bolts evenly and securely. Do not overtighten, as this could damage the plate or the hydrofoil.
  7. Final Check: Once installed, double-check that the hydrofoil is firmly attached and does not interfere with the propeller's movement or the engine's tilt/trim functions.

Troubleshooting & FAQ

How do I confirm this fits my engine?
This hydrofoil offers a universal fit for most outboard motors and stern drives in the 5-150 HP range. Please review the compatible brand list and dimensions (10-1/4" × 8-1/4") to ensure it can be properly mounted on your engine's anti-ventilation plate. Drilling is required for installation.

What performance benefits can I expect?
Properly installed, the hydrofoil will help your boat get on plane much faster, especially with heavy loads. It also reduces bow rise for better visibility, minimizes porpoising at speed, and can even improve fuel economy by allowing the boat to maintain plane at lower RPMs.

Is drilling required for installation?
Yes. This is a bolt-on accessory that requires drilling four holes into the anti-ventilation plate of your outboard or stern drive. All necessary stainless steel mounting hardware is included.

Offer lots of support and traction- perfect gym shoes
So comfortable- they offer a lot of support and I can tell they will last for a long time (and I’m hard on my gym shoes!). I’m actually a female but I sized down and they fit perfectly. I found them on sale and definitely recommend them as they are well worth the price.

Comfortable nike running shoes.
Size: 13, Color: Black/Summit White/Anthracite/Cyber, Size: 13, Color: Black/Summit White/Anthracite/Cyber
Nice and comfortable from the moment that I put them on my feet. Feels like you’re walking on memory foam. You have to buy comfortable shoes when you’re on your feet all day. I do Amazon Flex in. These will be perfect although I have several pairs so that way, the shoe lasts longer. Definitely would buy these in different colors very satisfied.

Good shoe, seems physically big
I really like these shoes. I’ve been able to wear them for about a week now and am really impressed with how they’re holding up. A lot of my shoes start to squeak in a similar amount of time and these still feel like they just came out of the box. I especially like the heal support, it feels like it’s really gripping the heal nicely My one complaint is that they seem physically larger than most size 11 shoes from Nike I buy. In spite of fitting the same inside, the actual shoe seems about an inch longer than my other Nike size 11s. It’s not a deal breaker and it doesn’t impact the comfort, it might even make them more comfortable, but they look a bit large on my foot. And if you have a narrow foot, you might be swimming in these.

Can’t Miss Shoe
Size: 11, Color: White/Blue Crystal/Total Orange, Size: 11, Color: White/Blue Crystal/Total Orange
Great looking shoe! Fit to form, I wear a size 101/2 or 11 and I ordered a size 11 and they fit perfectly. Soft and comfortable perfect for walking as I suffer from knee and back pain at 59 years old…. Don’t judge me. Normal width size for me so not sure about the wide fit but the toe room for me is comfortable. Great choice will definitely recommend.

Yes Go Nike!
These Nike men's shoes are very comfortable. It's a pretty versatile shoe. I am able to work out in the gym, go for hikes, walk on the street and run errands all with ease and comfortability. They are sturdy, have good cushion and great support for your joints and back keeping you aligned. They lean on the more narrow side for fit so if you have wide feet they may not work for you. The green around the heal is attractive. The price I paid for the shoes was extremely reasonable making them a great value. I have been using them for a couple of months now and they are still in great shape. Excellent buy!
