Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 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.

        Good marketing.

          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

                          Bad news.

                          1)I am a firm believer that if there was a really good reason for it the engineers would have built it into it. Especially after all these years and different manufacturers.

                          2)Bushing and bearing killers. 2 friends of mine had the same outdrive, same year and almost identical hours. Only difference, 1 had a hydrofoil and his pivot bushing/bearings went bad at about 200hrs.

                          They do help keep the bow down. If you do a lot of skiing with a boat not purposed for skiing it may be something you want to consider. If not, Iíd skip it.

                            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.
