Water Temp Sender Kit

The QUICKCAR RACING PRODUCTS Water Temp Sender Kit (QRP61-712) is a complete engine monitoring solution designed for marine and boating applications where real-time water temperature data is critical to engine health. Built for anglers, boaters, and marine operators who spend serious time on the water, this kit combines a precision sender unit, warning light indicator, and wiring harness into one integrated package. Whether you're running a tournament bass boat, offshore cruiser, or work vessel, knowing your coolant temperature at a glance prevents catastrophic engine damage and keeps you operating within safe parameters.

The system features a 1/2 inch NPT male threaded sender that installs directly into your engine block or coolant manifold, providing instant feedback to the blue warning light display mounted on your dashboard. The sender triggers the warning light at 235 degrees Fahrenheit, a temperature threshold that gives you adequate notice before thermal stress damages gaskets, bearings, or internal components. The complete kit includes the temperature sender, warning light assembly, and pre-terminated wiring harness, eliminating guesswork during installation. This three-piece design ensures proper electrical continuity and sensor calibration straight out of the box—critical for reliable operation in the harsh marine environment.

Marine mechanics and experienced boaters rely on sender kits like this to add or upgrade temperature monitoring on engines where factory gauges are absent or unreliable. The 1/2 NPT thread size is standard across most marine and automotive engine blocks, making this kit compatible with inboards, outboards, and diesel marine engines. Installation requires only basic hand tools and minimal electrical knowledge—the sender screws into the threaded port while the light mounts in your console and the harness routes through the engine compartment. For anyone serious about preventive maintenance and engine longevity, this Water Temp Sender Kit delivers measurable peace of mind during extended trips offshore or on inland waters.
