Yamaha Gauges - Trim Display Not Working

[Dan in Alaska]

We took the "new" boat out this weekend for the first run. The good news is that everything we did to the boat, as far as repairs or upgrades, worked perfectly. The Yamaha multi function tachs (round, cira 2001), however, are having some issues. Specifcally, the outboard trim display doesn't work. The port gauge always displays the lowest trim setting, and the stbd display always shows the highest trim setting.

I've never monkeyed with these gauges before, so I'm hoping someone will have some pointers on where to start looking. I'm guessing it's a loose wire, or something simple, since the rest of the gauge seems to work alright. Any pointers?

Dan, your problem is more than likely the trim position indicator on the engine. I will post a picture shortly.

What engines do you have Dan?

Oops, that would have been helpful......

I have twin 2001 F115's.

Also, do all of the 4" round Yamaha digital tachs have an hour meter? My 2003 did, displayed just below the RPM, but there's no hour meter display on either of these. Curious if they changed between '01 & '03?

Dan, see part number 1 and 3.

Part number 1 is the collar that mounts on the steering tube. They often break and are easy to replace.

Part number 3 in the actual sensor that gets moved by the collar. The sensor can get stuck and requires regular lubrication.

I believe the multi function gages changed in '03 to add more functionality, check with Andy (SIM.)

Awesome! Thanks, HOTSPOT. I'll take a look at them tonight.

When you order the sender, order a spare. They are not expensive, but they do tend to die.
