Hey guys,

I need some help here... I just mounted my omc outdrive sending unit to my 1990 Chriscraft 177 and it works fine except the reading on the gauge is backwards! when the trim is down the reading on the gauge is up and then the trim is up the reading on the gauge is down. Whats the problem here? What did I miss? Help!!!

Installed Up-side down, or wires reversed? ( I don't think it matters on the wires, but it may)

Try switching the wires first.

i'd double check that sender/striped, ground/black, and 12v+/purple wires are were they should be i think ground is bottom sender middle and purple/12v+ is on the top if its set up the same way as mine. unless of course if it wasnt working when you bought it maybe your senser/plastic thingy on transom housing was put on upside down but i highly doubt that is the issue.
