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.

  • 1996 johnson 115 top speed

    I have a 1997 18' Kenner, powered by a 1996 115hp Johnson. What kind of top speed should I expect, as of now with a full tank of gas (30 gals) and 2 people and gear it tops out at about 35mph and 5200-5400rpm and cruises at 30mph and 4800rpm. Is this where it should be or should I expect more from this motor? Motor runs excellent and is very dependable, maybe needs a higher pitch propeller?

    Any feedback would be appreciated.

      I have 1996 fast strike 115 on my ranger 681 fishing boat (17' glass maybe 11 degree deadrise). say 15 gallons of gas, two guys with gear, 3 batteries bow mount TM and a 9.9 sitting next to the 115 I get 42mph consistently with a once in a while 44mph GPS, I am spinning at WOT 5700-5800 rpm with a 17 pitch SS prop.

      I know at WOT I am above the WOT range but I like the hole shot, that's more important to me. I haven't dabbled with props yet, I may but that's my numbers.
