Mercury - Bravo Three XR Pro Finished Racing Propeller - 4-Blade Forward - 3-Blade Aft - 250 to 520 HP Outboards - 16 Dia. - 21 Pitch - 48-842939L70

Designed for 250-520 HP gas and diesel-powered sport cruisers and performance Bravo Three applications. A large diameter 4 blade forward propeller followed by a smaller diameter 3 blade aft propeller feature built-in cup for incredible handling, improved fuel economy at cruise and boat control. Intended for the Bravo Three XR drive and can be used with the Bravo Three and Bravo Three X drives. The Pro Finish provides a performance leading edge, consistent cup heights, zero balanced for minimal vibration, and durable high luster finish.

As a general rule, the odd pitch numbered Braco Three XR propellers run similar engine RPM to the next higher pitch even numbered Bravo Three propellers. For example, the Bravo Three XR 27 pitch matches the RPM of a Bravo Three 28 pitch with a satin finish.
