Airmar 33-218 Paddle Wheel F/ B44V/66V/66VL

The Airmar 33-218 Paddle Wheel F/B44V/66V/66VL is a professional-grade replacement component kit designed for anglers and boaters who depend on accurate speed and water data from their TRIDUCER multisensor transducers. After years on the water, you'll recognize that your depth, speed, and temperature readings are only as reliable as the paddle wheel mechanism that generates them—and when wear accumulates, accuracy suffers. This spare parts kit addresses the inevitable degradation that occurs with regular use, ensuring your Airmar B44V, B66V, B744V, and B744VL thru-hull transducers continue delivering the precision readings needed for navigation, fish finding, and safe boating operations.

The paddle wheel mechanism inside your TRIDUCER transducer works constantly, spinning as your vessel moves to measure water speed and calculate accurate position fixes. The Airmar 33-218 contains all the wearing parts required for a complete renewal: one paddle wheel assembly with shaft, four o-rings that seal against water intrusion and pressure, one valve assembly that controls water flow within the sensor body, and two pull rings for tool-free removal and reinstallation. These components are engineered to Airmar's exacting standards, ensuring that once installed, your transducer will restore factory-specification accuracy without the cost and downtime of purchasing an entirely new unit.

Professional charter operators, serious cruisers, and weekend warriors who log heavy water hours will find this kit essential for preventive maintenance and repair. The modular design means you can perform the service yourself or hand it off to your marine electronics specialist—no special factory equipment required. Installation is straightforward: the pull rings allow quick extraction of the old assembly, and the complete parts list ensures nothing is overlooked. If you operate a B44V, B66V, B744V, or B744VL transducer and have noticed sluggish speed readings, inconsistent data updates, or visible corrosion around the paddle wheel housing, this Airmar 33-218 kit will restore confidence in your onboard instrumentation and keep you navigating safely and fishing effectively.
