Installation Guide

  1. Safety First: Ensure the engine is off and the ignition key is removed. For added safety, disconnect the engine's battery.
  2. Position the Hydrofoil: Place the hydrofoil onto the anti-ventilation plate of your outboard or sterndrive's lower unit. Center it carefully side-to-side.
  3. Mark Drill Points: With the hydrofoil held firmly in position, use a marker to mark the center of the four mounting holes.
  4. Drill the Holes: Remove the hydrofoil. Using the included drill bit, carefully drill the four marked holes through the anti-ventilation plate.
  5. Mount the Hydrofoil: Align the hydrofoil with the newly drilled holes and insert the stainless steel bolts from the top.
  6. Secure the Hardware: Attach the nuts to the bolts from underneath and tighten them securely. Do not over-tighten, as this could damage the plate.
  7. Final Check: Once installed, ensure the hydrofoil is rigid and does not interfere with the propeller's movement. Reconnect the battery if it was disconnected.

Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my engine?
A: This hydrofoil has a universal design intended for most outboard and sterndrive engines rated between 40 and 300 HP. The key requirement is a flat anti-ventilation plate above the propeller where the unit can be mounted. Please measure your plate and compare it to the product dimensions (16.93 × 14.17 inches) to ensure adequate space.

Q: Does this require drilling into my engine?
A: Yes, installation requires drilling four holes into the anti-ventilation plate. The kit includes a drill bit and all necessary stainless steel hardware to complete the job.

Q: What is the primary benefit of installing a hydrofoil?
A: A hydrofoil provides lift at the stern, which helps the boat get on plane much faster at lower speeds. This also helps reduce or eliminate common issues like porpoising (bow bouncing) and improves fuel efficiency by allowing the engine to work less to maintain planing speed.

Definitely not worth the money you pay.
Size: 14 Ounce (Pack of 1), Set name: Standard
The dogs love them and they are great treats. The problem is for almost $20 a bag. You only get a fourth of the bag hole sweet potato strips. The rest of it is just the scraps from the skin. These get stuck in my dog’s gums and then their teeth and they’re hard to digest. I stopped buying them and went to another brand, unfortunately. I thought maybe it’s a fluke and the back got shook up, but I’ve ordered at least eight bags.
