5 reviews for Mercury Marine OEM Side Mount Remote Control & Trim, 20″ 8-Pin, 8M0138641
Perfect match for my 2008 Mercury 60hp on a fishing aluminum. The 20ft harness tucked away neatly, and the power trim lead integrated seamlessly with my bow switch. Starts and shifts without lag, even after a full day of walleye trolling. Built-in safety horn is piercingly effective, and the ergonomic lever reduces fatigue on extended trips. OEM durability means no worries—top-shelf control for the price!
This OEM 8M0138641 elevated my coastal skiff with a 2012 Mercury 150hp. The stainless steel resists salt corrosion like a champ, and the 8-pin harness plugged straight into my wiring loom. Handle-mounted trim makes beaching a breeze at speed, and the integrated horn alerts during high-RPM runs. Precise throttle control up to 35 mph—lighter and more responsive than my old aftermarket unit. Mercury nailed the reliability!
Great replacement for my aging control on a 1998 Mercury 50hp river jon boat. The 8-pin setup connected without adapters, and the 20ft harness gave me plenty of slack for custom routing. Trim switch responds crisply, and shift is buttery smooth even in current. Only minor hiccup was fine-tuning the cable tension post-install, but once set, it’s rock-solid. Quiet operation, no rattles—ideal for long hauls.
Installed on my 2010 Mercury 115hp pontoon setup, and it’s been flawless for family lake days. The side-mount ergonomics fit my right-hand drive perfectly, with the pull-to-open throttle feeling intuitive and responsive. 20ft harness routed cleanly under the deck, and the trim control syncs effortlessly with my engine. Loud warning horn adds safety for the kids aboard. Durable build at a fair price—runs like factory fresh after 25 hours of cruising!
Swapped this 8M0138641 onto my 2005 Mercury 90hp outboard, and it was plug-and-play perfection. The 20ft harness reached my console without splicing, and the 8-pin connector locked in tight. Power trim switch on the handle is a godsend for quick adjustments while trolling—smooth as silk up to 30 mph. Built-in horn blasted a clear warning during a test, and the stainless accents shrug off freshwater splashes. OEM quality shines—best upgrade for my bass boat!
