First Use Experience
The true test came when I installed the Sierra International 1867671 on my Evinrude. Installation took place at my home dock, and I was careful to follow all manufacturer guidelines. After wiring it in, I fired up the engine and tentatively pressed the trim switch.
The motor whirred to life, and the outboard smoothly tilted down. Relief washed over me as I raised and lowered the motor several times. The movement was consistent and powerful, restoring full functionality.
The Puget Sound is known for its unpredictable weather, and over the following weeks, I tested the trim motor in various conditions. It performed flawlessly in both calm waters and choppy seas. I encountered no issues with the motor’s function, even after prolonged use in damp conditions.

Maintenance has been minimal. I occasionally spray the motor with a corrosion inhibitor to protect it from the elements. So far, the Sierra International unit has far surpassed my expectations.
In comparison to the original OMC trim motor (when it was working!), the Sierra International seems to operate with more authority. The tilt and trim response is quicker and more precise, making boat handling noticeably improved. I feel confident that this replacement will keep my boat on the water for years to come.
