Installation Guide

  1. Safety First: Ensure the engine is turned off and disconnect the battery before starting work.
  2. Position the Hydrofoil: Place the hydrofoil onto the anti-cavitation plate, ensuring it is centered and properly aligned.
  3. Mark Drill Holes: Use a marker to carefully mark the positions for the four mounting holes on the anti-cavitation plate.
  4. Drill the Holes: Remove the hydrofoil and drill the marked holes. Ensure you use a drill bit appropriate for the plate material.
  5. Mount the Hydrofoil: Re-position the hydrofoil, aligning it with the drilled holes. Insert the provided stainless steel bolts with gaskets from the top.
  6. Secure Hardware: Attach the remaining gaskets and nuts from underneath and tighten them securely. Do not overtighten, as this can damage the anti-cavitation plate.

Troubleshooting & FAQ

Q: How will this hydrofoil improve my boat's performance?

A: This stabilizer is designed to get your boat on plane faster, reduce or eliminate porpoising (bouncing) and cavitation, and provide a smoother ride in rough water. By improving stability and lift, it can also increase fuel efficiency and allow you to maintain a plane at lower speeds.

Q: How do I know if this will fit my specific engine model?

A: This hydrofoil offers a universal fit for most outboard and sterndrive motors between 5 and 40 HP. Check the compatibility table above to confirm your brand is listed. Installation involves drilling into the anti-cavitation plate, which allows for flexible mounting on various models.

Q: What is the benefit of the dorsal fin style design?

A: The dorsal fin design helps to improve tracking and stability, reducing side-to-side slipping during turns and providing more precise handling, especially at higher speeds.

Q: OEM vs. Aftermarket?

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.

Almost Indestructible!
Size: Medium Set of 6
My dog LOVES these balls, and it's all about the squeaker (which my husband hates). The size is great and I don't worry about it getting lodged in her throat. They are very durable too. We had one lone ball for YEARS and I forgot it ever squeaked, but it was still in tact. I searched for a replacement because I was so impressed with it. Very happy to have found it. I just ordered some for my son's dog too. The squeaker may eventually come loose, but it's worth the money to buy again!

The most durable and fun dog toy of all
Size: Medium Set of 6
Most durable and fun toy of all. The only thing that I have found that can destroy these balls is a lawnmower. Probably good for keeping teeth clean too.

Dog approved
Size: 3.5" (Medium/Large Dog), Color: Set of 6
My 60lb 11mo puppy loves these balls! They do get a little softer the more she plays with them but they are light and squeezy enough for fun retrieve, catch, bounce and training. AND does not break things in the house since they are fairly squeezable. The sqeeky can be a little loud but it also helps get her attention and she is so excited to play with multiple ones. I'm also suspecting the plastic spikes may even help clean her teeth. They are the perfect size for a German shepherd. This multi-pack is great to have to use some outdoor, indoor, and i replace old ones after my pup gets them too dirty to wash.

The dogs favorite toys!
Size: 3.5" (Medium/Large Dog), Color: Set of 6
I have 3 German Shepherds. These balls are their favorite! They live to have me throw them and they love to chase them. They are outside toys, but they always try and sneak them in. I have purchased these quite a few times because they love them. The balls squeak and are soft enough for me to squeeze them, but tough enough that they don’t go right through them. When the squeaker dies, they still love to play with the balls until their squeezing finally breaks the ball. Remember they are outside balls, so they are in all kinds of weather. We do have other balls, but they don’t play them.
