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.

  • Planning

    I have recently purchased a 1996 18'3" bass boat with a 150HP mecury on it. It has had a jack plate installed on this boat prior to my purchasing it. It seems to take to long to get up on plane and also seems to plow through the water prior to planning out.Also, it cavitates quite a bit when trying to plane. Do you have any suggetstions on how I could correct this or can you lead me to someone that can help.Thank you in advance for your time,Tom

    Hey Tmagnum. I own a similar boat - '84 18ft bass boat w/150 merc - she used to take a long time getting up on plane and porposed a bunch. I put on one of those hydrofoils by Stingray and it helped a bunch. The motor was also sitting a little too high on the transom and by dropping it down one notch, it got more bite and didn't cavitate as much. Just thought i'd pass it along even though it may not help much. Goog luck.-Jersey

        Good morning, I am using a Quicksilver, Laser II prop. The #,s on the prop are as follows if I am reading them correctly.DCQuicksilver 48 16996 440 26PThank you in advance for your help,Tom

          That's a good prop. Can you get the top RPM's that you want? As Jersey13 mentioned, a hydrafoil will help. I prefer the larger ones one a V6, like a King Fin or Turbo Lift. Play with the jack plate height. Going down may help holeshot, but your top RPM's will decrease also. Can you tell if the prop has been reworked? Usually there will be more numbers stamped in the side somewhere.

            Re: Planning

            I really have not tried to extend the RPM's very high. I am not sure what the limit is for this motor. I can say that I have had it to about 4600.To me the prop does not look as if it has been reworked. The #,s I gave you are all that appear on it.Do you think that a hydra foil is the only cure other than lowering the motor on the jackplate and sacraficing top end.

              If you're sure your tach is correct, I think you are about 1000 RPM off. If so it's time for a new prop. Thats too far to repitch. Besides, it's worth good money to someone who can spin it.
