Performance Benefits

The Tempest Plus 14.6x17 is a prop built for those who know their boat and expect precision every time. It’s designed with a larger diameter that gives it incredible lift—helping the hull ride higher for better top-end speed and fuel efficiency. When you drop the throttle, it hooks up fast and clean, getting your boat on plane in seconds without excessive bow rise.

Once you’re up and running, this prop really shines. The unique blade geometry provides an ideal mix of grip and release, keeping your handling steady and responsive. Turns feel tight and confident, even when trimmed out or pushing through chop. It’s equally impressive at cruise, where vibration stays low and performance feels effortless.

The stainless steel construction adds muscle where it matters most. Built to take on impact, heat, and stress, the Tempest Plus holds its shape under pressure and resists corrosion in both freshwater and saltwater conditions. And with the Performance Vent System (PVS), you can fine-tune your acceleration by swapping vent plugs—dialing in the exact hole shot and responsiveness you want for your specific boat setup.
