Let’s Talk About Si-Tex SP-80-1 Autopilot w/Rotary Feedback
The Si-Tex SP-80-1 Autopilot w/Rotary Feedback promises cruise control for your boat, and after years of manually steering during long fishing trips, the idea of hands-free navigation was incredibly appealing. Si-Tex, a Manufacturer known for dependable marine electronics, offers this fixed-mount autopilot system designed for inboard, outboard, and sterndrive vessels. It seemed like the perfect solution to free up my hands for more important tasks like tending to lines and enjoying the scenery, so I decided to give it a try.
I was constantly battling fatigue on solo trips. I needed an autopilot system that was reliable, easy to use, and compatible with my existing hydraulic steering system.
Unboxing the Si-Tex SP-80-1, I was immediately impressed with the solid feel of the control head. The unit felt substantial and well-made, suggesting durability and resistance to the harsh marine environment.
Compared to simpler autopilots I’d researched, the Si-Tex SP-80-1 offered a richer feature set, including NMEA 0183 GPS integration and rudder feedback. This promised more accurate course keeping and integration with my existing chartplotter.
My initial excitement was tempered by a touch of apprehension, as the installation seemed more involved than simpler tiller autopilots. However, the potential benefits of precise, hands-free navigation far outweighed my concerns, leaving me eager to get it installed and tested.
Real-World Testing: Putting Si-Tex SP-80-1 Autopilot w/Rotary Feedback to the Test
First Use Experience
My first test of the Si-Tex SP-80-1 took place during a solo tuna fishing trip 50 miles offshore. I encountered moderate chop and a steady 15-knot breeze.
The autopilot engaged smoothly and held the set course remarkably well. Even in the moderately rough conditions, the boat stayed on course with minimal deviation, significantly reducing my workload.
Initially, navigating the menus took a bit of learning, but the intuitive layout and clear display quickly became familiar. The auto-trim function worked flawlessly to compensate for changing sea conditions.
I experienced one minor hiccup when the rudder feedback temporarily lost signal. However, the Ghost Rudder backup feature kicked in seamlessly, allowing the autopilot to continue steering based on its memory of rudder movements.
Extended Use & Reliability
After a full season of use, the Si-Tex SP-80-1 Autopilot w/Rotary Feedback has proven to be a reliable and valuable addition to my boat. The control head shows no signs of fading or damage despite constant exposure to sun and saltwater.
The system has performed consistently across a wide range of conditions, from calm inland waters to choppy offshore seas. The Si-Tex SP-80-1 requires minimal maintenance. I simply rinse the control head with fresh water after each trip.
Compared to the constant corrections required when manually steering, the autopilot has noticeably reduced my fatigue and improved my overall fishing experience. The peace of mind knowing that the boat is holding course while I manage tackle or grab a bite to eat is invaluable.
