Technical Performance
The PRB Propeller 1.73 x 1.6 is engineered with precision manufacturing techniques to deliver consistent hydrodynamic performance. The 1.73-inch diameter provides an effective working surface for water engagement, whilst the 1.6-inch pitch determines the theoretical distance the propeller advances with each complete rotation. This combination creates a balanced performance envelope suitable for deep-V hull designs like the Sonicwake V2 36, offering strong acceleration, stable top-end speed and predictable handling characteristics across varying water conditions. The 3/16-inch shaft bore is machined to tight tolerances, ensuring a secure fit on Pro Boat's flex shaft systems without play or vibration that could compromise performance or cause premature wear. As a genuine Pro Boat component, this propeller has been tested extensively to meet the manufacturer's performance and durability standards, making it a reliable choice for both competitive enthusiasts and weekend bashers running RC boats in the UK. The propeller's design balances thrust efficiency with smooth operation, helping to optimise overall boat performance whether you're chasing top speed or seeking nimble manoeuvring in tight courses.

Frequently Asked Questions
- What Pro Boat models is this propeller compatible with? — The PRB Propeller 1.73 x 1.6 for 3/16 Shaft is designed for Pro Boat vessels featuring a 3/16-inch flex shaft, including the Sonicwake V2 36-inch deep-V speedboat. If you're unsure whether this propeller fits your specific RC boat model, our knowledgeable customer service team at RC Model Shop is happy to help confirm compatibility before you order.
- How do I know if I need a replacement propeller for my RC boat? — You should consider replacing your propeller if it shows visible damage such as cracks, chips or bent blades, if you notice unusual vibration or noise during operation, or if your boat's performance has declined. Propellers are consumable items that can wear over time, and keeping a spare on hand ensures you can get back on the water quickly without delays.
- What is the difference between propeller specifications like 1.73 x 1.6? — The first number (1.73) represents the propeller diameter in inches, which affects the blade surface area and overall thrust generation. The second number (1.6) is the pitch in inches, indicating how far the propeller would theoretically advance in one complete rotation. These dimensions work together to determine the propeller's performance characteristics, with different combinations suited to different hull designs, motor power levels and intended use.
- Can I use this propeller with other RC boat brands? — This propeller is specifically engineered for Pro Boat models with 3/16-inch shaft compatibility. Whilst the shaft size may be standard across some manufacturers, we recommend checking your boat's manual or contacting our team to confirm compatibility before purchasing, as using an incorrect propeller can result in poor performance or damage.
- How should I maintain my RC boat propeller? — After each use, rinse your propeller with fresh water to remove salt, sand and debris that can cause corrosion and wear. Inspect it regularly for damage, and store it in a dry location. Apply a light coat of propshaft grease to the shaft bore to prevent corrosion and ensure smooth operation. RC Model Shop stocks genuine propshaft grease and other essential maintenance products to keep your RC boat in perfect condition.
