Help me I.D. this lead on the outdrive-gctid377028

[Guest]

Anyone know what this grounds/feeds/etc? Looks like it was attached to that screw, but not sure what it does. Not sure if it's keeping my speedo from working or not. It's a Bravo drive and the boat is a 1998.

Its a ground wire for your anoides. These all need to be attached for corrosion. Has nothing to do with speedo. There is a small hole in the back of your outdrive that allows water in. If you trim up your out drive there is a small hose the is attached that goes to your speedo. The hole in the back of out drive is probably plugged.

It is a common grounding wire.

Here is the kit with all the wires to give you a general idea of what all is connected.

Thanks guys! I'll get that reattached before launching this weekend. I checked the speedo hole and it had a good amount of crud in it. Used a paperclip and a little air pressure to clean it out. Hopefully that solves the problem.
