It restores throttle and shift control at the helm and integrates the handle-mounted trim\/tilt switch and horn provision so you don’t lose any marine-specific features when repowering or repairing. The kit is intended for Gen I cable systems and uses the traditional 8-pin connector with a 15-foot lead for straightforward wiring to engines that accept this harness style.\u003c\/p\u003e\n\n\u003ch3\u003eDoes this FASWORX control box match the original Mercury layout?\u003c\/h3\u003e\n\u003cp\u003eYes — the housing, handle orientation, and control logic mirror the OEM design so installation and operation feel the same as the factory unit.

It’s especially suited for those restoring original helm ergonomics after repowering or those who previously used Commander 4000 \/ MSC 4000 style side-mount controls. Before buying, confirm your engine’s connector type and whether your particular small four-stroke requires an extra adapter harness to ensure plug-and-play installation.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this replace Mercury part 8M0178521?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
