I have twin Bravo 1s and Faria guages for trim indication. The guages work intermittently.......

What is most likely the problem?

Thanks.

more then likly its in the senders, but could be any number of things from a bad ground to bad gauges but most times its in the sender leads....

you didnt give very much info...ie: make model type drives ect

Problem with sending unit

Could also be the wires are corroded. Replace the sending units, simple and only $80

I agree, probably senders, round modules on top sides of outdrive. Sort of a wiper effect sender, just two screws to take them off.

glad you think simple to replace...25 years doing this...easy for me but without the right tools and exp. not easy or simple....requires disassembling the transom bell housing(waiting for you to say splice them in..will only live a short time)

If the boat has been used in salt water be prepared for those two screws to snap-off!

What they said, senders. I would take this opportunity to switch to mechanical indicators.

OK I will agree. If you have done it before its simple. It really is No I would never splice a line, that's why you buy the complete kit.

No to the splice, but you can solder the wires into the new sender.

If you can get it off and apart, clean it thoroughly and fill with di-electric grease. This has worked well for me. Note where it is before loosening the screws.
