  • wings on your outboards????

    What is the correct name for those wings that people bolt to the cavitation plate and does it really help a tired outboard get up on plane?

    cheers

    The generic term is hydrofoil.

          They will help to lift the boat when over-propped or under-powered. - They also provide substantial drag.

                  When properly rigged, a hydrofoil, attached to the anti-ventilation plate.

                  Lowers planing speed, regardless of prop or power.

                  All of the negative myths about hydrofoils are supported by examples of being badly rigged.

                    And most, if not all, of the marketing is supported by a paucity of independent, empirical data.

                      These things have been discussed to death in these forums. Those who favor them amount to about 1% of those who have actually used them. Look at it this way, if they provided any significant benefit the manufacturers would have designed the AV plate that way.

                        this is what I really wanted to here.
                        Never had big enough motor to put one on and didn't know if they worked.

                        thanks

                            I put a home made set on a 9.9 merc I have because I was running it on a boat with a 21" transom and the motor was a short shaft. I had only the one motor then and it was not very deep in the water. At a slow creep it was fine but once it got moving it would suck air. With the rig on the motor it would keep more water on the prop. It didn't take the place of a long shaft motor but I was able to use the boat.

                              So that entire subject doesn't need to be typed out again here's a link to a recent thread on the same topic. In your application it may help to get you on plane if used incorrectly, but its not what you need.
