  3. Drilling: Remove the hydrofoil and carefully drill the marked holes using the included drill bit.

  5. Securing: Insert the bolts from the top and fasten them securely with the provided nuts from the bottom. Do not overtighten.

Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my motor?

A: This hydrofoil features a universal design intended for most outboard and stern drive motors from 40 to 300 HP. It mounts directly to the anti-cavitation plate. To ensure a proper fit, we recommend measuring your plate and comparing it to the hydrofoil's dimensions of 16.93 × 14.17 inches.

Q: What are the main benefits of installing this hydrofoil?

A: The whale tail design improves performance by getting your boat on plane faster, reducing or eliminating porpoising (bow bouncing), and enhancing stability at both low and high speeds. Its control tips are engineered to improve thrust and reduce drag.

Q: What tools are needed for installation?

A: The package is comprehensive and includes all necessary mounting hardware (4 sets of screws and nuts) and a drill bit. You will only need a drill to create the mounting holes on your engine's anti-cavitation plate.

Love them
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I wear a size 11.5 in ladies shoe and these just barely fit. Butttt after I put lotion on my feet and slipped these on and left them on for about 30 mins. It left my feet really soft! They work great as intended. Would buy again

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.
