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.

    Sounds like Bennett trim tab system. Go to the link below and you will find every thing you ever wanted to know about them there.
    PS, while you are having fun at the site, the fill is on the front of the reservoir under that plastic cover.
    It's a small black cap. You can find the answer in the FAQ, also in the link below.

      not sure did look at site and looks alot like the system on board. are you saying the plastic cover that is on top and has the hoses running to it i think it has three screws that hold it onto the reservoir. if i remove these three screws it should lift off correct. i apoligise i am new to boating and not sure about all these things

        I'm only guessing by your description. Look at the link. If it's not what you have, then a picture of what you have would be handy. A previous owner may have replaced the original system.
        Bayliners back then normally used the Boat Leveler type system.

          ok it is a Bennett system i filled it up tonight and got the tabs working some what the tab on the right side looking toward the bow of the boat is working great goes up and goes down the one on the left does not do anything thought it might be stuck so i stood on the swim platform and tried to move it with my foot and i can get it up and down by applying pressure to it so the cylinder is not stuck pulled the motor off the reservoir to look at the pick up tube seems fine the motor was a little warm like it was over working when i was trying to get the left tab to move what could be the problem

            You may have a solenoid on the pump not working or the wiring to it is defective or a bad switch. Impossible to say for sure, but if you go to the Bennett site link I gave you earlier and locate the troubleshooting section.
            With that and a meter, you will find the problem.
