Side Mount Remote Control with Trim Switch Mechanical Engine Controls 8M0176291. OverviewThis is one of those controls that's been around because it works. Plain and simple. The trim switch is built right into the handle, so when you need to bump the motor up or down, your hand is already there. No reaching. No thinking about it. You just do it.. It comes with a 20-foot harness already attached and uses the AMP 10-pin connector. On the engines it's meant for, it plugs straight in. No adapter harness, no extra parts run, no wondering why something won't talk to something else. These get used a lot on MY2005 and newer small Mercury FourStrokes-8, 9.9, 15, and 20 HP-especially on side console boats and small rigs where mechanical controls still make the most sense.. Key Features. • Trim switch mounted directly on the handle where it should be • 20-foot harness gives you plenty of length for most side consoles • AMP 10-pin connector for direct plug-in on compatible engines • No adapter har
