Trim Sendor Wiring Removal

[Horigan]

First post...

I'm trying to remove the trim sender wiring from the transom on my '95 OMC Cobra SX. It looks like gasket sealant or something was used and I'm afraid if I pull on the wiring too hard I'll be left with just the rubber grommet in the transom passage. Yes, I removed the clip. Is there a trick to getting the rubber grommet out, other than trying to work a screw driver in to the hole from the engine side?

Thanks in advance.

Finally got the sender removed and I thought I'd share my experience. I improved access to the internal passage of the wiring by removing the raw water hose from the transom pipe. This allowed me to see the sender wiring as it came through the transom with a mirror. Make sure you remember to re-install this hose when you're done!!! I found removal and installation of the clip holding the wiring inside the transom was best done with my hands/fingers, not with needle nose pliers. On the outside with the drive lowered and steered fully port I used a long flat head screwdriver to try to pry the mushroom end of the rubber gasket out, as well as pulling on the wiring. On the inside I also used a smaller flat head screwdriver to pry the sides of the wiring to break any sealant. With all the pulling I could do from the outside I could not get the rubber gasket to pull out, only partially. I even stripped the wiring so bare wire was pulling out with the rubber gasket still in the transom. I ended up using the big screwdriver drive to break apart the mushroom head end of the rubber gasket. I then cut off the sender, tied a knot in the exposed wiring I had pulled out, then pulled the wiring out from the inside.

Installation was pretty easy. I used synthetic grease on the new rubber gasket, threaded it in to the transom, and it easily fully seated when pulled it in from the inside. Installing the clip blind was pretty easy, and luckily, it's magnetic so when you drop it, you can retrieve it with a magnet. I was so relieved to finish the job I buttoned it up and forget to re-install the raw water hose. That will be tonight's project.

I adjusted the sender so at full down the needle reads at the bottom of the blue range on the dial. I'm pretty happy with accuracy of the gauge after repeated up and down cycles.
