Sierra 18-5898 Sender-Temp 240°F 1/2-14 Dual Station Product Description
Equip your marine engine with reliable temperature monitoring using the Sierra temperature sender designed for precision at 240°F. This robust unit features a 1/2-14 NPT thread and supports dual-station setups, ensuring accurate readings across multiple helm locations without signal loss or interference. Ideal for boat owners who demand dependable performance on the water, it delivers consistent signals to your gauges, helping you spot overheating issues before they escalate into costly repairs.
Crafted from high-quality materials resistant to corrosion and harsh marine environments, this sender stands up to saltwater exposure, vibration, and temperature swings common in boating. Whether you're cruising inland waters or tackling offshore adventures, it provides the peace of mind that comes from knowing your engine's temp is always in check.
Standout Features for Superior Performance
- Precision Calibration: Triggers at exactly 240°F, matching OEM specs for accurate gauge response.
- Dual-Station Ready: Seamlessly connects to two gauges or helm stations, perfect for multi-station boats.
- Standard Threading: 1/2-14 NPT fits most marine engine blocks without adapters.
- Durable Construction: Stainless steel body and sealed internals resist moisture, fuel, and oils.
- Easy Wiring: Simple two-wire setup with color-coded leads for quick integration into existing systems.
Perfect Fit and Hassle-Free Installation
This sender bolts directly into common engine head or manifold ports on popular inboard and sterndrive setups. It replaces a wide range of OEM senders, restoring factory-like performance without modifications. Before installing, clean the mounting port thoroughly and use thread sealant on the fitting to prevent leaks.
Quick Installation Steps
- Disconnect the battery and drain coolant if needed.
- Remove the old sender using a deep socket wrench.
- Install the new unit, torque to manufacturer specs (typically 15-20 ft-lbs).
- Reconnect wires, refill coolant, and test at idle.
- Monitor for leaks and verify gauge readings during a sea trial.
Pro tip: Always match polarity on dual-station wires to avoid crossed signals between stations.
Long-Term Reliability and Maintenance Insights
Investing in this Sierra sender means fewer false alarms and more time on the water. It eliminates erratic readings caused by worn probes or poor seals, which plague lesser parts. Regular checks—every season—keep it performing: Inspect wires for chafing, ensure the probe is submerged in coolant, and clean any buildup on the threads.
Boat maintenance veterans know that proactive temp monitoring prevents engine seizures, warped heads, and impeller failures. This unit's fast response time gives you an early warning, letting you throttle back or dock safely before trouble hits.
