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.

  • power tilt & trim won't go down.edited.re-edited

    I have a 85 evinrude outboard.I've installed a new electric motor for the tilt and it goes up perfectly, but i can not get it to go down unless i use the release screw.Please help!! I think it is an 79 or 80.And yes the electric part of it does sound like it is working or at least trying to.Re edit;I'm starting work now and was wondering how much hydraulic fluid to put in? There is no window to see level?

    Trevor.... What year is the engine? Does the electric motor run in the down mode?

      trevor, if the trim motor is running and the fluid reservoir is full and the manual release valve is closed,try this...with engine supported by the lock mechanism,find the check valve located below the port side trim ram.it is approx. 3/4" in dia. and looks as if a very large screwdriver would fit it. remove it with the largest screwdriver you got ,{buy a cheap one if you need to**some fluid will come out ,but not all.then get a #10 nut, look in the hole that the check valve came out of you will see the shuttle valve , it has a stem on it . use a small pick or screw driver and put the nut over this stem. then install the check valve carefully.it is only catching a few threads.you need to be listening for a pressure release in the trim unit so things need to be quiet around you at this time{really**.ounce you hear the pressure release then remove the check valve ,and the nut and reinstall the check valve. the trim should work now. good luck ,john
