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.

    Re: trim pump HELP

    it looks like you have the calco pump assembly. The one in pictures looks complete. the pump is round and recessed into bottom of reservoir. it is the part that rubber hose is attached to. When the calco pump and/or motor fail to operate then it is often best to replace the entire pump+motor with one made by prestolite. Prestolite version is interchangeable with calco. Prestolite was used on a lot more engines (including IO) and even after 40 years is still maintainable.

    Prestolite trim motors are still in production

    Prestolite valve bodies are still rebuildable

      Re: trim pump HELP

      On the prestolite pump it looks like ill have to get a new valve body because the one on my pump is different. I really would like to put a new motor in mine . But if you think its better to change out the whole pump/motor assembly.thank you for your help

        if you hunt around you can find used prestolite OMC stringer pumps for under $100. Stringer pumps are water resistant instead of waterproof because they are meant for inside transom.

        use plastic sealant to make the stringer trim motor waterproof(ish) and run until motor dies.

        run valve body until engine drifts down and then get it rebuilt.

        The rams typically last 25-35 years. The trim rams are not fully predictable as the trim sensor will often leak and cause pre-mature failures. Nonetheless, in general the rams never actually break. They just start leaking and the water can cause rust which can ruin the entire (very expensive) system. With ram rebuild kits only $30ish it is not worth risk. As soon as oil starts leaking out top of ram - rebuild them.
