Seachoice Marine Gauges & Sending Units: Reliable Fuel Monitoring on the Water
For any boater, knowing how much fuel remains in the tank isn't just a matter of convenience — it's a safety essential. Seachoice has built its reputation since 1988 as a trusted supplier of marine hardware and OEM-quality replacement parts, and their lineup of Gauges & Sending Units reflects that same commitment to dependable, no-fuss performance on the water.
Seachoice is committed to delivering quality marine accessories and OEM replacement parts to satisfy fishing, boating, and watersports enthusiasts worldwide — run for and by boaters, offering a wide-ranging product line. That boater-first mindset is evident in how their gauge and sender products are engineered: straightforward to install, broadly compatible, and built to hold up in the marine environment.
What Seachoice Offers in Gauges & Sending Units
Seachoice's gauge and sending unit catalog covers the core needs of recreational and fishing boat owners. Their product range includes fuel gauge kits, adjustable float-arm fuel tank senders, and reed switch sending units — the three building blocks of any marine fuel monitoring system.
- Fuel Gauge Kits (e.g., Model 15501): The 15501 kit can be used for gas or diesel and combines the 15421 sender and the 15441 fuel gauge — a black bezel, low-profile design for 12V negative ground systems, complete with a light kit. It fits a standard 5-hole pattern, works with most marine fuel gauges using the industry-standard 33–240 Ohm range, and the gauge fits a standard 2" hole.
- Adjustable Float-Arm Senders: The adjustable fuel tank senders can be used for gas or diesel and are made of non-ferrous materials, compatible with 35 (full) to 240 (empty) ohm gauges, with mounting screws and gasket included. The float arm can be rotated in 90° intervals to assure clearance with tank walls or baffles. Models cover a wide range of tank depths, from 4" to 27", making them adaptable to many hull configurations.
- Reed Switch Sending Units: Reed switch senders are compatible with most fuel gauges on the market today, working with 33 (full) and 240 (empty) ohm gauges, and feature no moving mechanical parts — making them extremely durable. These senders feature stainless steel immersion tubes for corrosion resistance in demanding marine conditions. Multiple tube lengths are available, ranging from 150mm (6") to 450mm (18"), to suit varying tank depths.
Why Choose Seachoice for Fuel Monitoring?
One of Seachoice's key advantages in this category is broad compatibility. Their senders and gauges are designed around the marine industry's standard ohm ranges, meaning they integrate cleanly with most existing onboard electrical systems without requiring specialized wiring or adapters. Seachoice is committed to delivering premium quality products at a competitive price, and runs a no-hassle warranty on everything they produce. That warranty peace-of-mind is especially valuable when you're relying on a sending unit that lives inside a fuel tank.
Whether you're replacing a failed sender on a bass boat, upgrading a worn-out gauge on a center console, or outfitting a new build, Seachoice's gauges and sending units offer a reliable, cost-effective solution backed by decades of marine industry experience.
