Performance Benefits

The Mercury Tempest Plus 8M0151384 is where precision meets performance. From the moment you open the throttle, you’ll feel the prop dig in and grab water with authority. Its large-diameter, three-blade design gives you strong bow lift and lightning-fast planing without losing grip in the turns. It’s fast, steady, and beautifully balanced exactly what you want when you’re running light, loaded with gear, or trimming high.

At cruising speeds, it delivers a smooth, confident feel with consistent midrange power and stable handling. The prop’s geometry helps reduce slip, letting your boat cut through the water efficiently while keeping speed and control steady. When conditions get rough, it holds its grip, giving you a clean, predictable ride every time.

The Performance Vent System (PVS) gives you control over how your prop behaves. Adjust the vent plugs to customize your hole shot open them for faster acceleration or close them for more bite under heavier loads. It’s real-world performance tuning that lets you match your prop to your exact boating style.

The stainless steel construction resists flexing, corrosion, and wear, ensuring maximum efficiency and strength season after season.

Why It’s a Strong Choice
