  • Bellows replacement

    Ok getting ready to do bellows trim senders and lower shift cable. What do you guys use to run up the shift cable before you pull it for a guide. I was thinking weed eater string I guess. Also my gauge nor my trim limit works. I bought new senders. If I take my trim limit wires and hook together then my trim limit switch should work right. It's just a switch. Also my trim gauge sender just goes to ground right. So if I ground that wire my gauge should move. First time messing with senders so tips and advice needed

    Any small cord or heavy twine will work as a fish line for pulling the new cable back in. Weed eater line is fine, as long as you can tie it tight on the cables.

    I'm not following your question about the trim/limit senders. Trace down their current wires inside your boat. They come into the transom plate above the engine coupler shaft. There is pair for both trim limit and trim position. There is normally only one way to connect them to the harness. So start with this with your new sender/switch and everything should work fine.

    You can bypass the trim limit switch by jumping the two harness connectors. But why if you have the new one? You can get your outdrive into trouble fast if you power up with the drive above it's trim range.

      Since you are doing the bellows anyway I would just replace the trim switch and sender.

        I have a length of mechanics wire with part of an old sleeve from the front of a cable attached to it. I just screw it into the cable and pull it through.
        If you want to test the gauge, ground the brown wire with a white tracer coming out of the engine harness.

          I assume you are wanting to test to make sure it is the senders that are the problem, and that everything else is working... So, yes, where the limit switch wires would connect to the trim pump harness, just jump them together and the trim UP switch should work (all the way to full UP).

          Yep, just touch the brown/white wire in the engine harness to ground and the gauge should pin to full DOWN...

          Here is a wiring diagram of the trim pump harness that may make things clearer.

            Thanks achris!

            I've been looking for a wire diagram for the trim system for quite some time and this is the first I've run across with wire colors that match what I have. It's a project boat and of course over time the wiring has been hacked. The tilt and trim senders were gone which likely caused the issue with the bellows being torn off. Most of the wiring was spliced together with household wire nuts which says a lot about how this was taken care of. Thanks again.

              No problem. That was originally a black and white diagram, but I coloured it using 'Paint'. I also added the trim gauge sender into the drawing, for clarity. I also have one that includes the transom mounted trim switch and its connectors...
