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.

Information that I have been looking for
Format: Paperback
The information in the book is so enlightening. If I had only known about energetic boundaries years ago, it would have saved me a lot of pain in relationships, and boosted my morale and self-esteem, when I needed it most. Life, and dealing with others, can be so draining! The information in this book is literally life saving. I have come to love everything that Cyndi Dale has published, because her teachings really resonate with me and what I need to learn about. Cyndi Dale is so eloquent in her explanation of what otherwise would seem really "far-out", "weird" or "woo-woo". I love Cyndi Dale and Donna Eden, for the reasons stated above.

Fascinating, informative, but not for everyone.
Format: Paperback
The idea of a human energy field is not new; numerous books have been published on the subject, many of which I've seen on Amazon. I do think it makes sense, to some extent, that the human body should be surrounded by such a field or fields. As the author herself states, our psyche and spirit need protection just as much as our physical body does. The author of this book, Cyndi Dale, cites numerous scientific sources as evidence that these fields do exist. Of course, Kirlian photography has been around for many years now. For those who might not be familiar with this type of photography, it's basically a technique used to photograph the electrical discharges surrounding people and other living beings, including plants. Dale briefly discusses this process in the first chapter, "Energy and our Energetic Fields". This book also deals with the subject of the chakras, which are centers of energy in the physical body, and are also part of what is known as "the subtle body". These centers of energy are a well-known aspect of Hindu beliefs, and specifically, the yogic tradition. Although I do feel that much of New Age philosophy, psychology, and spirituality needs to be taken with a grain of salt, I nevertheless enjoyed reading this book. It's not one for casual reading, either; in fact, studying it will yield more food for thought than just one reading will provide. The author introduces the concept of energy balancing with an exploration of the four basic energy boundaries -- the physical, the emotional, the relational, and the spiritual. These are actually comprised of several of the twelve auric layers surrounding the physical body, and each has a different color, when viewed clairvoyantly; the physical is red, the emotional, orange, the relational, green, and the spiritual, white. She also discusses what life events can have detrimental effects on each of the boundaries. Next, she presents the eight specific boundary issues that most people will typically encounter. These she calls "spiritual syndromes". The first of them is named "The Paper Doll Syndrome", the basic manifestation of which being an endless repetition of the same troubling pattern in at least one area of a person's life. This might be, for example, a substance addiction that the person can't seem to break, or a pattern of getting involved in abusive relationships, also persistent in spite of therapy. The second boundary issue is named "The Vampire Syndrome". This one deals with the curious phenomenon of feeling energetically drained after being around certain people. It can manifest as a feeling of exhaustion, frustration or lack of motivation, as well. The third boundary issue, known as "The Mule Syndrome", is related to being a workaholic, of feeling duty-bound to take up the slack for others. It even involves worrying about others' concerns, to one's own detriment. Of course, physical exhaustion, as well as anxiety and depression, are also part of this boundary issue, which is related to co-dependency. The fourth boundary issue is named "The Psychic-Sensitive Syndrome". This one is specific to those people who are psychically gifted. It includes those who are highly empathic, as well as those who are able to sense supernatural beings. Admittedly, this sounds a little scary to me.... Physical symptoms such as anxiety and insomnia are typical of this syndrome, unsurprisingly enough! Dale mentions three other boundary issues -- "The Healer's Syndrome", which afflicts not only those in the medical or intuitive healing fields, but also those who are extremely kind-hearted; "The No-Boundary Syndrome", in which people are constantly hyperactive, as well as hypervigilant, and "The Environ Syndrome", which involves extreme sensitivity to environmental surroundings. Dale offers various solutions to all of these syndromes, starting, of course, with one's own self-diagnosis to see which one(s) a person might be affected by. From there, she discusses such things as visualization, guided meditations, color and crystal therapy, and sound therapy. I must admit to some skepticism as to the validity of using crystals for psychologically therapeutic purposes, because it just seems too "way out there". Some of the qualities Dale claims for crystals just seem to have no basis in scientific fact. Colors, on the other hand, do have valid psychological associations, although I'm not totally convinced of the therapeutic benefits thereof. Subsequent chapters deal with working on boundary issues to help in specific areas, such as work and success, financial issues, relationships, and parenting. Specific techniques that I do think are useful are "Uncovering Your Storyline", which is a means of digging into one's psyche in order to discover the origin of one's boundary issues, the use of sound therapy (music has scientifically been proven to profoundly affect the brain, and therefore, moods), visualization, and prayer. Although the author refers to God mostly as "the Divine", she does have a rather Christian-sounding tone in these sections of the book. I especially like her reference to "streams of grace" coming from God to take away the symptoms of the above-named syndromes. Again, this is a book that can be best appreciated by studying it, and putting its techniques into practice. While perhaps not everything will be helpful to individual readers (this depends on each reader's beliefs, as well as degree of skepticism), there is much to reflect on here, psychologically as well as philosophically speaking, not to mention the spiritual sense. Each chapter in the book is annotated, with references to scientific research articles on the Internet, for instance, as well as spiritually-related ones. There's also a bibliography for further reading. The tone of the writing is very soothing and peaceful, yet, the concepts discussed will ensure the reader's full attention. Dale never talks down to her readers, nor doe she engage in filling her chapters with any kind of jargon; in fact, she explains potentially new or confusing terms in clear, easy-to-understand language. In short, this book will not only be appreciated by veteran New Age adherents, but also by those who are open-minded enough to investigate a field of knowledge that might not entirely be sanctioned by the scientific establishment, yet, remains totally fascinating!

Energizing
Format: Paperback
As a spiritualist Cyndi Dale is in a league of her own. She uses science, psychology and spirituality to explain her beliefs. She has a strong grasp of the energy systems - neural, cardiac, muscular, biochemical, electrical, magnetic, and esoteric. How each is vital on it's own and how each is affected by the others. How the mind, environment and contact with others affects the body's energy systems. In this book she covers the above along with Chakras, Meridians, spirit types, auric layers and much more. This book teaches and heals.
