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.

Wife and cat approved!!!
Color: Grey, Size: Queen, Color: Grey, Size: Queen
The BEDELITE Fluffy Queen Comforter has been a great addition to our bedroom. It has a soft, plush feel right out of the bag and fluffs up nicely once laid out. It strikes a nice balance of being lightweight while still keeping us warm and cozy, which is perfect for year-round use. My wife immediately noticed how soft it felt, and it really does make the bed feel more inviting at the end of the day. What surprised me most is how much everyone in the house seems to love it—our cats practically live on the bed now because of how comfortable it is. The fabric feels gentle against the skin, and it doesn’t have that scratchy or noisy texture some budget comforters do. Overall, it’s a cozy, well-made option that delivers good warmth and comfort at a reasonable price.

Soft, Warm & Cozy
Color: Navy Blue, Size: Queen
The BEDELITE Fluffy Queen Comforter Set is absolutely wonderful. I purchased it for my 75-year-old mom during her visit to Oregon, where the weather can be quite cool, and it was the perfect choice. The sherpa material is unbelievably soft and cozy without being too heavy. It kept her warm and comfortable, especially in the evenings, and she commented multiple times on how soft and luxurious it felt. The quality is excellent, and it looks great on the bed as well. If you’re looking for a warm, plush comforter that’s gentle, cozy, and ideal for cooler climates or older guests, this set is a fantastic purchase. We’re very happy with it and would definitely buy it again.

Review of bedlite fluffy comforter
Color: Grey, Size: Twin
The bed light fluffy twin comforter was terrific and well-made. I would say, however, as a person who runs cold that I needed to put an extra blanket on top of it. The comforter is warm for the spring and fall, but not for the winter. The other thing to mention is, it is a light comforter, and not a thick comforter for the winter. Overall, I would recommend the comforter is worth the value of the money you paid for it.
