Raymarine Paddle Wheel Replacement Kit

Restoring accurate speed readings on your boat has never been easier with a reliable paddle wheel replacement. When your marine speed sensor starts faltering—delivering erratic data or grinding to a halt—swapping in a fresh unit keeps you navigating with confidence. This kit breathes new life into your existing transducer housing, ensuring precise measurements through the water without the hassle of full system overhauls.

Boat owners know the frustration of sluggish performance from worn-out impellers. Salt buildup, marine growth, or simple wear can throw off your log readings, affecting everything from trip planning to racing splits. A straightforward replacement gets you back to reliable speed-through-water data, complementing your GPS for true performance insights.

Why Choose This Paddle Wheel Replacement?

• Precision Engineering: Crafted to match original specifications, it spins smoothly to deliver spot-on speed and distance logs, even in choppy conditions.
• Durable Materials: Resists fouling from algae and barnacles, extending service life in harsh saltwater environments.
• Easy Retrofit: Drops right into compatible housings—no special tools or downtime required for most setups.
• Enhanced Accuracy: Low-drag design minimizes turbulence, providing cleaner data for your displays and autopilot integration.

Unlike makeshift fixes or generic parts, this kit maintains the factory-calibrated performance your Raymarine instruments expect, avoiding calibration headaches down the line.

Perfect Fit for Your Setup

Designed for seamless integration with popular through-hull transducer mounts, it works hand-in-glove with legacy speed instruments. Ideal for sailboats, power yachts, and fishing vessels where dependable log data is non-negotiable. Pair it with multifunction displays for layered insights—combine speed-over-ground from GPS with true water speed for optimized trim and fuel efficiency.

"After years of exposure, my old wheel was toast. This swap took 20 minutes and my readings are crisp again—night and day difference on long passages."

Step-by-Step Installation Guide

1. Prep the Boat: Haul out or careen the vessel for hull access. Clean the transducer housing thoroughly to remove debris.
2. Remove Old Wheel: Gently pull the worn paddle wheel from its insert, twisting if needed to free it from the shaft.
3. Inspect and Lube: Check the housing O-rings for cracks; apply marine grease to the new shaft for smooth rotation.
4. Insert New Wheel: Align the blades and slide it home until it seats firmly—listen for that satisfying click.
5. Test in Water: Relaunch, power up your instruments, and verify smooth spinning at various speeds. Recalibrate if your system prompts.

Pro tip: Do this during annual haul-out to bundle maintenance. Always wear gloves—those blades can pinch!

Maintenance for Longevity

Keep your investment spinning strong with routine care:

• Flush with fresh water after every saltwater outing to dissolve salt crystals.
• Inspect seasonally for nicks or imbalance; a quick spin test by hand reveals issues.
• Use anti-fouling paint sparingly on the housing exterior—avoid the wheel itself to prevent imbalance.
• Monitor for erratic readings: Often a sign of trapped line or growth, fixable without full replacement.

Regular upkeep can double the lifespan, saving you trips to the yard.

Common Issues and Fixes

No Speed Reading? Check for air bubbles in the thru-hull or a stalled wheel—prime the system by filling the tube.

Inconsistent Data? Imbalance from debris; remove, clean, and realign.

Overreading? Worn bearings—time for replacement to restore factory accuracy.

These quick diagnostics empower DIYers to troubleshoot without calling in pros.
