PRB Right Side Propeller, CCW Rotation, 1.4x1.65, 3/16 Shaft Z-PRB282028

Key Features

• 2-Bladed Design — The two-blade configuration offers an excellent balance between speed and efficiency, delivering smooth acceleration and consistent thrust across a wide range of throttle inputs. Two-blade propellers are the industry standard for small RC boats because they provide stability without excessive vibration, making them ideal for both competitive racing and casual weekend bashing sessions.
• Metal Construction — Manufactured from durable metal materials, this propeller offers superior strength and longevity compared to plastic alternatives. Metal propellers can withstand the stresses of high-speed operation, repeated runs, and minor impacts with debris or shallow water obstacles, ensuring your investment in replacement parts lasts through multiple seasons of operation.
• Right-Hand, Clockwise Rotation Specification — This propeller is engineered for non-standard, right-hand clockwise rotation, which is specifically matched to the Zelos 36 Twin's port-side mounting position. Proper rotation direction is essential for balanced thrust delivery in twin-motor catamaran setups, where port and starboard propellers must work in synchronisation to maintain straight-line tracking and responsive steering control.
• 3/16 Inch Shaft Compatibility — The inner diameter of 3/16 inch (4.7mm) ensures a secure fit with the Zelos 36 Twin's motor shaft and drive coupling system. This standardised shaft size is common across many Pro Boat models, though it's always important to verify your specific vessel's requirements before ordering replacement propellers for any RC boat.
• Direct Fit Replacement — This is a genuine OEM replacement part specifically engineered for the Pro Boat Zelos 36 Twin catamaran, guaranteeing perfect fitment and performance characteristics matched to your boat's twin-motor brushless drive system. No modifications, adaptations, or workarounds are needed—simply install and run.
• Optimal Thrust Dimensions — The 1.4 x 1.65 inch (35.5 x 42mm) specifications represent the ideal balance of diameter and pitch for the Zelos 36 Twin platform, delivering smooth power delivery across the full throttle range whilst maintaining excellent control authority at all speeds.

Technical Performance

The PRB Right Side Propeller represents genuine engineering quality from Pro Boat, a brand recognised and respected throughout the RC boating community for precision manufacturing and performance-oriented design. The metal construction provides superior durability compared to composite or plastic alternatives, resisting the cumulative stresses of high-speed operation, engine torque load cycles, and exposure to aquatic environments where salt water, chlorine, sand, and debris create challenging operating conditions. The 1.4 x 1.65 inch dimension has been specifically calculated to optimise thrust delivery from the Zelos 36 Twin's twin brushless motor configuration, providing the power and responsiveness competitive RC boat racing demands whilst maintaining the stability and tracking characteristics necessary for controlled operation across varying water conditions. The right-hand clockwise rotation specification is critical in twin-motor catamaran setups, where synchronised rotation between port and starboard propellers creates balanced thrust vectoring for straight-line acceleration and responsive directional control. With a 3/16 inch (4.7mm) shaft aperture, this propeller integrates seamlessly with the Zelos 36 Twin's motor coupling system, engineered to maintain precise alignment and eliminate unwanted vibration or runout during maximum RPM operations typical of brushless high-performance RC boats running 3S and 4S LiPo battery packs.

Frequently Asked Questions

• What does CCW rotation mean and why does it matter for my RC boat? — CCW (counter-clockwise) and clockwise rotation specifications refer to the direction the propeller blades turn when viewed from behind the boat. This propeller is engineered for right-hand, clockwise rotation, which is critical in twin-motor catamaran setups where port and starboard propellers must rotate in opposite directions to create balanced, symmetrical thrust. Installing a propeller with incorrect rotation direction will create violent vibration, tracking problems, and potential damage to your vessel's internal components including the motor coupler and flex shaft.
• Will this propeller fit my Pro Boat RC boat? — This is a direct fit replacement specifically engineered for the Pro Boat Zelos 36 Twin catamaran. It is also listed as compatible with several other Pro Boat models including the Sonicwake 36 and Veles 29. However, propeller compatibility is critical and can vary significantly between models. Before purchasing, verify your specific boat's model number and consult either the manufacturer's manual or contact our experienced RC team who can confirm whether this propeller is suitable for your particular vessel and mounting position.
• Is this a genuine Pro Boat product or a third-party aftermarket propeller? — This is a genuine Pro Boat OEM (original equipment manufacturer) replacement part, manufactured to the exact specifications and quality standards of Pro Boat's original equipment. Genuine OEM parts ensure perfect fitment, optimal performance, and durability. We stock only authentic Pro Boat components, not aftermarket alternatives that may compromise fit, balance, or performance on your valuable RC investment.
• What is the difference between port and starboard propellers, and which side does this one fit? — Port and starboard propellers are mirror-image components designed for opposite sides of a twin-motor catamaran. The port (left) propeller typically features right-hand clockwise rotation when viewed from behind, whilst the starboard (right) propeller features left-hand counter-clockwise rotation. This PRB282028 is specifically engineered for port-side (left-side) installation on the Zelos 36 Twin, rotating clockwise to provide balanced thrust alongside the starboard propeller. Never install a port propeller on the starboard side or vice versa, as this will create severe handling problems and potential mechanical damage.
• How often should I replace my RC boat propellers? — Propeller replacement frequency depends on usage intensity, operating conditions, and maintenance practices. Professional racers may change propellers after every competition, whilst casual weekend bashers might replace propellers once or twice per season. Inspect your propellers regularly for blade damage, erosion, cracks, or bent edges. Any visible damage compromises performance and can cause vibration and stress to internal components. Having quality spare propellers on hand allows immediate replacement during sessions, maximising your water time without interruption.
• What materials are boat propellers made from and why does metal construction matter? — Pro Boat propellers are manufactured from durable metal alloys selected for strength, vibration damping properties, and resistance to corrosion. Metal construction provides significantly superior durability compared to plastic or composite alternatives, particularly in the demanding environment of high-speed RC boating where cavitation forces, motor torque loads, and aquatic debris create substantial stresses on the propeller. Metal propellers maintain dimensional stability across extended operating sessions, resist warping from heat or UV exposure, and tolerate impact with rocks or shallow water obstacles far better than plastic equivalents.
• Can I use this propeller on RC boats other than Pro Boat models? — Whilst this is a Pro Boat OEM component, it may be compatible with non-Pro Boat vessels sharing identical shaft size (3/16 inch) and rotation requirements. However, we strongly recommend verifying compatibility before purchase, as performance characteristics and mounting interfaces can vary substantially between manufacturers. Consult your boat's manual or contact our experienced RC team for guidance on compatible propeller options for vessels outside the Pro Boat range.
