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.

  • outboard overrevs on turns

    I have a quicksilver 300 inflatable and it is a great handler, able to turn on the spot at high speeds and very light. The problem I have is with the engine revving out like it has slipped out of gear on tight high speed turns. This has happened with more than one outboard on this boat. I get the impression that it is cavitation from the wash created by the tail pods from doing these turns. Is there a way to reduce this or is it the price you pay for being able to turn so quickly.

    Your prop is sucking air, AKA - ventilating.Maybe ask the question in the 'prop' section.

        If you can't trust a comment like 'Great Ebayer AAAAAA++++++++!!!!!!!!' Then there is something wrong with the world.Seriously though thanks for the link Roscoe. I'll look into the postage costs but these may help the slow to get on the plane problem I also have.

          Naturally the motor pictured will cavitate in turns. Look at the prop. If it were me I'd take the money for those tabs and put toward a prop with at least some cup.

            That is a typical symptom of the motor being mounted too high. 1" can make a difference.

              Are we not pushing Smart tabs anymore or aren't they made for inflatables?

                Another reason why many long-time inflatable owners run long shaft engines on their boats. Performance props for that size engine are few and far between. Either slow down, don't turn as sharp, or get a long shaft. You are tempting fate by continuing to take high-speed tight turns in a light inflatable.

                  Now those tabs are what I would call fugly. How on earth does that boat reverse?
