Raymarine ST900/P17 Speed/Temp Long Body Plastic low Profile Thru-Hull with 10m Cable
Raymarine ST900/P17 Speed/Temp Long Body Plastic low Profile Thru-Hull with 10m Cable — Product description
Unlock Precision Boating with Advanced Speed and Temperature Sensing
Imagine gliding through the water with pinpoint accuracy on your vessel's speed, even at those tricky low speeds during docking or trolling. The Raymarine ST900/P17 stands out as a game-changer for marine enthusiasts, combining a high-performance Gen2 paddlewheel with fast-response temperature sensing in a sleek, low-profile thru-hull design. This long-body plastic sensor delivers reliable data to keep you informed, whether you're racing, cruising, or fishing.
Key Advantages for Everyday Use
- Superior Low-Speed Accuracy: Starts logging speed from just 0.3 knots, perfect for precise maneuvering in marinas or slow drifts.
- Extended Speed Range: Smooth, linear performance up to 45 knots ensures dependable readings across all conditions.
- Quick Temperature Feedback: Captures water temp changes rapidly, ideal for spotting baitfish zones or monitoring engine cooling.
- Retractable Design: Pull it up easily for cleaning or winter storage without hauling the boat—saves time and hassle.
- Versatile Analog Output: Seamlessly integrates with a wide array of Raymarine displays and legacy setups for straightforward upgrades.
Crafted with durability in mind, this sensor's plastic housing resists fouling while maintaining a low drag profile that won't disrupt your hull's hydrodynamics. Boaters report fewer false readings and more consistent performance compared to older paddlewheel models, making it a smart choice for both recreational and competitive sailing.
Effortless Installation and Long-Term Reliability
Setting up the ST900/P17 is straightforward for DIY boaters. The long-body thru-hull fits most hull thicknesses, and the included 10m cable provides ample reach to your instrument panel. Drill a clean hole, bed it in marine sealant, and secure—most installs take under an hour. For best results, align the paddlewheel parallel to the water flow, ideally forward of any prop wash.
Pro Tips for Peak Performance
- Position amidships on the hull bottom for minimal turbulence interference.
- Flush the paddlewheel monthly with fresh water and a mild anti-foulant to prevent marine growth.
- Core compatibility with Airmar P120 or B120 housings means easy swaps if you're retrofitting an existing setup.
- Pair it with Raymarine's i-series instruments for digital precision that rivals high-end multifunction displays.
Regular upkeep keeps it spinning smoothly season after season. Retract it during layup to avoid damage, and you'll enjoy years of trouble-free operation on the water.
Perfect Fit for Your Marine Electronics Ecosystem
This sensor shines when connected to Raymarine's i40, i50, or iTC-5 instruments, feeding analog signals that translate to clear, real-time dashboards. It's also a drop-in upgrade for older ST60 or ST80 systems, breathing new life into vintage cockpits. Fishermen love the temp data for contour trolling, racers trust the speed logs for handicap calculations, and cruisers rely on it for fuel-efficient planning.
Beyond Raymarine gear, its standard output plays well with third-party loggers, broadening its appeal for custom builds or multi-brand helm stations.
Frequently Asked Questions
What makes the Gen2 paddlewheel in the Raymarine ST900/P17 better than traditional sensors?
The Gen2 paddlewheel offers responsive startup at speeds as low as 0.3 knots and maintains linear accuracy up to 45 knots, reducing errors in low-speed scenarios like docking or fishing.
Is this sensor compatible with older Raymarine instruments?
Yes, its analog output works seamlessly with i40, i50, iTC-5, and legacy ST60/ST80 systems, making it ideal for upgrades without full replacements.
How do I clean and maintain the ST900/P17 transducer?
Retract the sensor for easy access, rinse with fresh water, and apply a mild anti-fouling solution. Avoid harsh chemicals to preserve the plastic housing.
Can I use this in saltwater environments?
Absolutely, the durable plastic construction and thru-hull design handle saltwater exposure well, with proper installation and maintenance.
What's the benefit of the low-profile design?
It minimizes drag and turbulence on the hull, improving overall boat performance and speed readings while reducing vulnerability to impacts.
Does the 10m cable length suit most boats?
Yes, the 10m cable reaches most instrument panels from thru-hull locations, with extension options available if needed.
Is the ST900/P17 retractable for off-season storage?
Yes, the retractable piston allows simple removal without dry-docking, protecting it from ice or debris.
