Turning Point Express Mach3 OS Propeller - 15.6x17

The Turning Point Express Mach3 OS Propeller - 15.6x17 is a 3-blade stainless-steel boat propeller designed as part of Turning Point’s interchangeable propeller system. Its blade geometry is intended to provide dependable acceleration, handling, and cruising performance when the propeller diameter, pitch, rotation, and hub application are correctly matched to the boat and engine.

The stainless-steel construction balances marine durability with the performance characteristics expected from this propeller family. Propeller selection has a direct effect on engine rpm, hole shot, load carrying, fuel use, and top-end performance, so pitch should be chosen around the engine manufacturer’s recommended wide-open-throttle operating range rather than appearance alone.

A compatible Turning Point hub kit may be required and is not assumed to be included unless specifically listed with the product. Confirm engine make, horsepower, gearcase size, shaft configuration, rotation, hub-system compatibility, and current propeller performance before ordering. After installation, verify wide-open-throttle rpm under normal operating load.

• Matching pitch and diameter to the engine helps balance acceleration, cruising, and wide-open-throttle rpm.
• Compatible hub-system options allow the propeller to be matched to supported engine applications.
• The 3-blade design gives the operating characteristics associated with this Turning Point propeller family.
• Checking loaded wide-open-throttle rpm confirms whether the selected pitch is appropriate for the boat and engine.
