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 threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

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

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

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

  • 1989 Johnson 150 V6 GT Max Rpm's

    I have a 1989 Johnson 150 V6 GT and was wondering what is tha maximum rpm's this engine is rated at and is it okay to keep it at this maximum for any period of time? I have had this setup which is a 1989 Stratos 285 Pro and the 150 HP Johnson for only about 2 months now. Is there a site or link where I could find out more info on this motor and boat? Johnson's and Stratos's site on list the latest boats and motors. How does one find info on older setups.Also I'm new to this forum and wonder if there is anyway that I could find post on just 1989 Johnson's 150 HP motors rather that looking at some 16,000 plus post to find info on my Johnson?A New Boat Owner,Mike

    I would try for around 5800 with an average laod. Always use fresh 87 octane and Champion plugs and you should be good to go. Watch the water pressure.Good luck!
