Designed for higher-horsepower single-outboard bay boats and multispecies hulls under heavy loads, Mercury‘s Bravo I LT four-blade propeller improves planing and trim response, resulting in increased top speed, Mercury says. The prop features a diameter of 15¼ inches and comes in 15 pitch offerings, from 20 to 27½ inches, for two- and four-stroke outboards. The Bravo I LT features Mercury’s Performance Vent System, which enables anglers to dial in the prop for peak performance. The Bravo I LT costs $740.42.
