We recommend 3-Blade propellers for recreational boats with 3 4 and 6 cylinder outboards and IO engines.

High-speed boat propeller design. One of the many considerations of high-speed marine applications is transmission and propeller design. The design of high-speed propellers can also present a complex design problem. Therefore the tip sections of propellers operating at Mach numbers above 07 should be designed to operate at small lift coefficients below 05 too.

High propeller efficiency translates to improved fuel economy and increased vessel speed. Strong each product has been strictly tested. Delivery time is 3-6 days via express shipping methods.

Chris Bush famed MOD-VP and Formula One tunnel boat racer re portedly had a marked influence in the design of Mercurys latest drag and top-speed wheelthe Lightning ETThis new prop has made a big name for itself in the few years since its introductionwhile touted as a drag racing propits found a welcome home on the propshafts of high-performance bass- and sportboats as a top speed. Our speed boat propellers are approved by CCS ABS DNV BV NK KR GL etc. Specifically tip cavitation and vortices have been eliminated or significantly reduced providing the following benefits over tradition.

In the current arrangement a CR propeller is placed at the forward end of a pod which is aligned with the local inflow. When blades spin a pressure difference between the forward and rear surfaces is produced accelerated. Each region has different design limitationslcriteria depending on the speed of the vessel.

A contrarotating CR propeller design with a tractor pod for a high speed patrol boat is addressed. A boat propeller is a fan mechanism that transmits power by converting rotational motion into thrust. We will offer the certificate per as customers request.

Usually consisting of 3 or more blades a boat prop spins around a central shaft to create dynamics similar to a rotating screw or airfoil. For this discussion the tunnel geometry is described in Figure 1. With some changes in propeller this boat achieved 173 mph.
