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.

  • johnson power tilt still leaks down

    I've checked the manual release, fluid level, there is no external fluid leaking. Can some one send me a diagram of the setup, or tell me if there is a valve stuck or something along that nature?
    Any help would be appreciated. Thanks

      It has an internal rubber valve which wears out and leaks. I rebuilt mine, it's a JOB! and pretty soon it started leaking again.

        It has more than 1 internal valve. If the o ring at the manual release valve is ok, and you're not leaking at the trim or tilt cylinder piston or sleeve o rings, your problem will lie with 1 of 2 valves. The first is on the port side, below the motor. If you look beneath the motor, there will be 3 spots for pressure testing the unit. Check the valve in between the first and second spot, counting in from the boat side. The second valve you should check is also beneath the motor, but pretty much centered beneath it. It is inline with the second pressure test spot (the middle one) that I spoke of, right after the line "bends" or turns into an elbow. Check them in that order. The first valve that I spoke of is usually at fault when both the tilt and trim leak down when left standing, the second valve is usually at fault when the tilt leaks down but the trim holds while left standing. When checking these valves what you are looking for is that they are full and free movement of core, that the outlets are not clogged and that there is no dirt, chips in seat area holding valve open, causing it to lower. Let me know what you find. Gl Chris
