One side is for your limit switch and the other is for the gauge. I believe the port side is the guage but I'm not 100% sure. It says on the caps. Anyway, the one that is making your gauge move is the right one and may need to be taken apart and cleaned. They get some corrosion in there sometimes. They're basically metal contact points.

Also, make sure you didn't screw up your limit switch. If you adjusted that you may not be able to trim it out enough to get speed so check it on the trailer.

Gero they come as a kit, merc part # 805320A 1, they go through the transom assembly and can be a bear to change if you have never done it, it can be done in less than an hour if you have the right tools, otherwise merc's flat rate time is over 4 hours, remove everything bar the transom assembly, now you can do what some novices do and cut the wires and use heat shrink connectors but it will not last more than a year, my 2 cents.

............and here's the bad news, They are a weak part of the Mercury outdrive. They'll probably break again soon.

Seems to me you cold change the inside guts, too.

Plus those gauges seem to be inconsistant and innacurate. I never used it so when I bought new guages I didn't even bother getting a trim gauge. I replaced it with something else.
