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.

My favorite toothbrush for my fur babies!
Color: Pink (2-pack)
I think these brushes are the easiest way to brush your fur babies teeth. I can get into their mouths and really see in there and brush each tooth and make sure the tarter is off. They even assist by trying to bite the brush and I use toothpaste for dog and gently brush back and forth first the front teeth then the side teeth then the inside teeth and the top of the teeth then the inside of the bottom and top teeth and I end with the left inside top and bottom teeth. I use vanilla mint toothpaste for dogs because my dogs are allergic to proteins. Their teeth look so white and their vet comments that their teeth look so great and clean. She does want them of course to have their yearly cleaning but she said there is no rush because their teeth are so clean and she sees no dental disease. I make sure that I wash the brushes daily with soap and keep them open after use otherwise mold will grow on them if you shut them in the case they come in. My pups weigh 6 lbs and 7 lbs and are Maltese females. They cooperate fully with me brushing their teeth because I started when they were puppies and now they are one and two years old. These brushes are lightweight and not expensive at all. I usually buy several at a time to make sure I have clean ones on hand just like you would change a human toothbrush monthly. Each pup gets its own toothbrush and I label the case for each with a marker. I like these better than a regular toothbrush because it’s 360 degrees and the pup can chew on it without hurting themselves or the bristles coming off. Highly recommend!

Dog Approved - Highly Preferred Over Standard Toothbrush
Color: Neon (4-pack)
These pet finger tooth brushes work well for me and my dog. He most definitely tolerates these so much more than a standard tooth brush. I believe I am able to reach more of his teeth and that I'm more effective brushing with these than I am with a standard brush. I put one on each of my index fingers. This makes it easier to do each side and the top and bottom without having to twist and turn to reach everything. The size is just right for my index fingers. They are a little tight getting them on and I have found that wetting my finger and the inside of the finger brush makes it a lot easier to put them on. The bristles on the finger brushes are soft, yet they are durable enough to give some good scrub quality and gum massage. These are a good price for what you get. I purchased the four-pack at right about $16.00. I have gotten numerous uses so far out of the two that I have been using. I will definitely purchase these again when it is time.

Probably Best for Medium-Large Size Dogs
Color: Blue (2-pack)
This finger cot–style toothbrush works well and is a simple way to brush your dog’s teeth, especially if they’re not comfortable with a traditional toothbrush. The material is soft yet effective at cleaning, and it gives you good control while brushing. The only drawback is that it’s a little large for my miniature Dachshund’s mouth, making it somewhat difficult to reach all areas comfortably. It would probably be a better fit for medium or larger dogs. Even so, it gets the job done and is a good option for introducing dogs to regular dental care.

The easiest and best tooth brush!
Color: Pink (2-pack)
Ive tried several other dog tooth brushes for my 74 lbs Coonhound. This style and brand is the only one that is easy and works for us. It's easy to move your finger around and all sides of it have the cleaning nodules so no matter which way your finger turns, they are always touching her teeth. I like to try to open her mouth and get the inside of the mouth too. I loop my finger around her fangs. It is soft without harder parts so it doesn't make her pull away. This brush is perfect. It's a good quality and comes with a container for storage.
