Tempest Plus 14.625 X 19 Mercury RH Propeller

The Mercury Tempest Plus 14.625 X 19 RH Propeller 48-8M0151381 is a high-performance three-blade stainless-steel propeller designed for large freshwater fishing boats and other performance-oriented marine applications. With a 14.625-inch diameter and 19-inch pitch, this right-hand rotation propeller is engineered to provide an effective combination of speed, acceleration, bow lift, and handling.

The Tempest Plus features Mercury’s distinctive blade geometry and large-diameter design, making it particularly suitable for bass boats, walleye boats, multi-species fishing boats, and selected bay boat applications. Its stainless-steel construction provides the strength and durability needed for demanding boating conditions.

Performance-Focused Blade Design

The Mercury Tempest Plus 14.625 x 19 propeller uses a three-blade design with aggressive geometry engineered to generate strong lift and maintain dependable handling. The large 14.625-inch diameter is particularly useful for applications where the outboard is mounted relatively high, while the propeller’s geometry is designed to maintain performance as the boat accelerates.

The Tempest Plus is known for providing strong bow lift, making it a popular choice for larger and heavier fishing boats where maintaining the correct running attitude is important. Its design balances acceleration and top-end performance while providing responsive handling.

Performance Vent System

The Tempest Plus 48-8M0151381 incorporates Mercury’s Performance Vent System (PVS) with three ventilation holes. PVS allows the ventilation characteristics of the propeller to be adjusted by changing the vent plugs.

This system can help boat owners fine-tune hole-shot and acceleration characteristics for their specific boat, engine, load, and operating conditions.

Stainless-Steel Construction

Built from premium stainless steel, the Tempest Plus is designed to withstand the demands of regular marine use while maintaining its blade geometry and performance characteristics. Stainless-steel construction also makes the propeller a strong choice for boat owners looking for a durable performance upgrade over conventional aluminum propellers.

Applications and Compatibility

The Mercury Tempest Plus 14.625 x 19 RH Propeller is listed for a range of Mercury and Mariner applications, including 90–115 HP Command Thrust four-stroke outboards, 135–400 HP Mercury and Mariner two-stroke and four-stroke outboards, and selected MerCruiser Alpha One and Bravo One sterndrives. Exact fitment depends on the engine, gearcase, propshaft, and hub configuration.

For 90–115 HP Command Thrust applications, Mercury specifies that the propeller is intended for the Command Thrust gearcase and not the standard 90–115 HP gearcase. Different hub kits are required depending on the engine and propshaft configuration.
