Real-World Testing: Putting Sierra International 1873131 Upper Swivel Gimbal Ring Shaft For MerCruiser Alpha/Gen Ii/Bravo I/Ii/III & Vazer to the Test
First Use Experience
I installed the Sierra International 1873131 on my boat, a 21-foot bowrider with an Alpha One Gen II drive, in my garage. Installation took a few hours, referring to the service manual and a couple of online videos was all I needed. The first test was a shakedown cruise on a relatively calm lake.
The difference was immediately noticeable. Steering felt lighter and more responsive; the boat tracked straight without constant corrections. This was a vast improvement over the previous stiff, almost notchy feel.
There were no immediate issues. The shaft performed flawlessly, and the boat handled like new.
Extended Use & Reliability
After a full season of use, including numerous trips to both freshwater lakes and saltwater bays, the Sierra International 1873131 has held up admirably. There are no signs of excessive wear or corrosion. The steering remains smooth and responsive.
Regular greasing of the gimbal ring is essential, but the shaft itself shows no indication of needing replacement any time soon. Compared to the OEM shaft, which failed prematurely, the Sierra International part seems significantly more durable. This part has far exceeded my expectations.
