Sierra 18-99607 99607 NMEA 2000 WIF (Water In Fuel) Module Only Product Description

Protecting your boat's engine from water contamination starts with reliable detection. The Sierra NMEA 2000 Water in Fuel (WIF) Module steps in as a smart upgrade for marine enthusiasts who rely on their vessels for long outings. This compact module connects effortlessly to your existing NMEA 2000 backbone, transforming basic fuel filter checks into automated alerts right on your multifunction display (MFD). Imagine heading out on the water without the constant worry of undetected water buildup in your fuel system—whether you're running gas or diesel engines.

Water in fuel isn't just an inconvenience; it can lead to serious issues like injector clogs, corrosion in fuel lines, and even complete engine failure if it sneaks past your primary filter. Boaters who've dealt with contaminated tanks know the hassle of manual inspections. This module changes that by providing real-time monitoring, giving you peace of mind during cruises, fishing trips, or competitive races.

Key Benefits for Serious Boaters

  • Proactive Engine Protection: Spots water before it hits critical components, preventing costly repairs and downtime.
  • Instant Visibility: Pushes notifications directly to compatible MFDs, so you stay informed without leaving the helm.
  • Versatile Fuel Compatibility: Works seamlessly with both gasoline and diesel setups, ideal for multi-fuel boats.
  • Network Efficiency: Leverages the power of NMEA 2000 for low-power, high-reliability data sharing across your entire system.
  • Durability in Harsh Conditions: Built to withstand marine environments, from saltwater spray to engine bay vibrations.

Many skippers upgrade to this after experiencing fuel-related hiccups. One common story: a diesel trawler owner caught a fuel-water mix during a coastal voyage, thanks to timely MFD alerts, avoiding what could have been a multi-day repair job.

How the WIF Module Enhances Your Setup

This isn't a standalone gadget—it's the bridge between your fuel filter's sensor and your boat's digital nervous system. Paired with a compatible water-sensing probe, it continuously samples fuel for conductivity changes that signal water presence. Once detected, it broadcasts a standardized NMEA 2000 PGN message, which supported displays interpret as a clear "Water in Fuel" warning.

Standout Features:

  • Plug-and-play backbone connection—no complex wiring or soldering required.
  • Low current draw keeps your battery happy during extended anchoring.
  • Compact design fits snugly near fuel filters without cluttering tight spaces.
  • Supports standard NMEA 2000 alert protocols for broad MFD compatibility.

From center consoles to larger yachts, this module integrates without fuss, elevating your fuel management game.

Simple Installation for Quick Upgrades

Most boaters complete setup in under an hour. Start by mounting the sensor at the lowest point of your fuel filter or separator—where water naturally settles. Connect the sensor leads to the module's terminals, then drop the module onto your NMEA 2000 T-connector or backbone spur. Power comes straight from the network (12V DC), so no extra batteries or fuses needed.

Pro Tips for Flawless Setup:

  • Ensure your NMEA 2000 network is powered and devices are talking (use a basic terminator check).
  • Route cables away from high-heat areas and exhaust paths.
  • Test the system post-install by simulating water (a drop of water in a test container works wonders).
  • Label your spur for future maintenance—saves headaches later.

No marine electrician required. If you're handy with basic tools, you're set. Always double-check your MFD's manual for WIF alert activation—some need a quick config tweak.

Perfect Fit for Modern NMEA 2000 Networks

Designed for boats equipped with NMEA 2000-certified MFDs from leading brands, this module shines in setups supporting fluid level and alarm PGNs. It's a natural add-on for systems already monitoring engine data, GPS, and radar. Gas outboards, inboards, sterndrives, and diesels all benefit, especially those with secondary fuel-water separators.

Think of it as the missing link in your network: while your engine ECU handles RPM and temp, this handles fuel purity. Expandable too—add it alongside oil pressure or tank level senders for a fully monitored vessel.

Real-World Impact on Boating Reliability

Water enters fuel via condensation in tanks, bad ethanol blends in gas, or sloppy refueling at marinas. Diesel users face extra risks from microbial growth in humid climates. With this module, offshore anglers detect issues early, tournament bass boats avoid mid-race failures, and liveaboard cruisers maintain systems effortlessly.

"Switched to NMEA 2000 WIF after a scare with emulsified diesel. Now, alerts pop up before I even smell trouble. Game-changer for peace of mind." – Experienced trawler captain

Investing here means fewer tows, less fuel waste from contaminated batches, and engines that run smoother longer.

Frequently Asked Questions

What does a NMEA 2000 WIF module do?

It monitors for water in your boat's fuel system and sends alerts to your multifunction display via the NMEA 2000 network, helping prevent engine damage from contamination.

Is the Sierra WIF module plug-and-play?

Yes, it connects directly to your NMEA 2000 backbone with a simple T-connector or spur, requiring no special wiring or programming.

Does it require a separate sensor?

Yes, it pairs with a dedicated water-in-fuel sensor probe installed at your fuel filter for accurate detection.

Can it be used with both gas and diesel engines?

Absolutely, it's compatible with gasoline and diesel fuel systems, making it versatile for various boat types.

Which MFDs support WIF alerts from this module?

Any NMEA 2000-compatible multifunction display that handles standard water-in-fuel alarm PGNs, common in popular marine electronics brands.

How reliable is water detection in the module?

It uses conductivity-based sensing to reliably differentiate water from fuel, alerting at thresholds before significant contamination occurs.

What's the typical installation time?

Most users install it in 30-60 minutes, including sensor mounting and network connection.
