It uses a 2-wire electrical connection and a 3 bolt mounting pattern, matching the original motor's fit and function so the trim system operates as designed. The housing is metal construction with a silver finish, and the motor runs on a standard 12 Volt DC marine electrical system. This is a direct interchange for the Yamaha 6H1-43880-02-00 tilt\/trim motor, giving boat owners a way to restore tilt and trim operation without sourcing the original Yamaha part.\u003c\/p\u003e\u003cp\u003eThis motor is intended for outboard owners whose trim system motor has failed, is drawing excessive current, or is no longer tilting or trimming the outboard smoothly. Because it shares the same 2-wire connection and 3 bolt mount as the original equipment motor, installation follows the same wiring and mounting steps used for the OEM unit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
