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.

We had a hot request for a workstation in the warehouse with some privacy. These have worked great. Easy to assemble. They are lightweight and stable. This was an inexpensive solution that looks professional. Our client loved it.

Dont wait! Assemble right away! Just in case you need to return it.
Color: Black, Size: 22" - 4 Panel
Ok, I like the idea of this but the assembly is frustrating. One side lined up perfectly with the holes however, the small bars that connect the screen to base is not lining up. I think it's do the fabric the screen or divider is made of. It's not stretchy. I brought this months ago and just opened it today. I'm upset and don't even think returning it is possible. If the material was a bit longer or stretchy to give a little room to work with this divider would be great. However, I'm not sure what I can use it for since I'm unable to attach it to the bottom. Beware! Don't wait like me. Tip for the manufacturer. Next time invest in Velcro dividers so the fabric can be adjusted with ease. Literally if I take the screen off the frame aligns perfectly. However, it defeats its purpose of privacy. I might buy some material myself and create a more flexible divider. Or I'll buy Velcro myself and attach to the bottom. I don't know yet.
