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.

  • rotten wire in outdrive

    bought a 1985 doral 164 with a 140HP mercruiser 3.0L and outdrive ....

    engine block is cracked from not being drained for winter ....
    I already have the replacement engine on hand .....

    when i pulled the engine out , i noticed that there is two double wires coming out of the outdrive .one goes to the trim pump (split in two )
    the other one is totally rotten ......

    are those wires exclusively for the trim pump ?

    if so ,do I have to remove the whole outdrive to fix those ?

    and then, where can I download my outdrive service manual ?

    thanks a lot for your advices ...;-)

      Re: rotten wire in outdrive

      Most likely its for the trim limit switch The other one would be for the trim sending unit - to the dash gauge

          Most people forget trying to replace the trim limit switch and the sender. A lot of work for very little gain.

          Having said that, you do need to pull the outdrive if you haven't already to check the various parts as mentioned above. You will also need to check your engine alignment when you reinstall your new engine.

                  Re: rotten wire in outdrive

                  the previous owner says that he had the outdrive rebuilt 3 years ago for over $1200.00 ....funny that they dint change this wire



                  because if those wires are only for the limit switch ....ill take great care of not going too far

                  but in any case , where can I download the outdrive manual ?

                    The wires are not actually in the outdrive - they are part of the transom assembly.

                    I'm not sure of the manuals are still available in the stickey at the top of the page or not... I think they were removed. But you may take a quick look at see.

                      thing is , know nothing about boats ......

                      just dont want to break something when stripping

                      Id like to fix those two wires ,but if I have to tear down the whole thing to bare parts just for a gauge reading , i doubt it is worth it !

                      the good wires go to the pump control

                          Re: rotten wire in outdrive

                          If your trim limit switch still functions you could just splice wire to the broken ones inside the boat. Take your trim limit switch off Its the one on the port side of the drive that covers the hinge pin. See if its rusted to sh!&. and get yourself a meter and run a test thru the cut off wires from inside the boat and see if you have continuity. You may be able to jury rig it if the switch is still functional. On the starboard side is the sending unit that sends a signal to a dash gauge to indicate the position of your drive Do you even have a trim indicater on you dash ? If not dont even wory about the starboard switch. I dont think there is a way around removing the drive and bellhousing to run the wires thru the transom . If you follow the wires from the switchs on the outdrive up to the transom you will see they disappear into never never land above the u joint bellows. There are i believe 2 screws that have to be acessed to remove the gromet that holds the wires from the aft end of the transom. As I said before then you should do [or at least inspect] the whole works Bellows, water hose, check gimble bearing alingment u joints etc

                            Re: rotten wire in outdrive

                            correct me if i`m wrong ...looks like the "rear end "
                            is in two parts : transom & outdrive ....

                            can I remove the outdrive as a whole unit and check the wires at the transom ?

                            there seems to be four bolts holding the outdrive to the transom
                            is this right?
                            thanks again !
