Mercury Marine produces a broad selection of Standard Finish propellers that deliver outstanding performance for recreational boating. To serve high-performance and racing customers, Mercury Racing offers its 20 propeller lines in two finish levels: Pro Finish and Lab Finish. The most popular Mercury Racing propeller models, the Bravo I and Revolution 4, are offered in both Pro and Lab Finishes. The Bravo I FS, LT, XS, XC, and Revolution 4 XP are all Pro Finish propellers.

r. In most applications switching from a Standard to Pro Finish propeller will permit stepping up one inch of pitch due to the ability of the Pro Finish to generate higher RPM. The opportunity to run a propeller with more pitch can produce a 2- to 5-mph increase in top end-speed – simply from bolting on the propeller.

Mercury Racing Lab Finish propellers follow a similar journey but are taken to the next level with additional blade thinning, which creates a sharper wedge that cuts through the water with less power-robbing drag and, once again, an increase in top-end RPM and a step up in pitch by about one inch with a corresponding gain in top speed, compared to a Pro Finish model. Mercury Racing Lab Finish props are especially effective on lighter-weight high-performance boats capable of running above 80 mph. Lab Finish props are durable but the ultra-crisp blade edges must be maintained to retain peak performance.

Mercury Racing offers a diverse line of propellers that are continually tested and improved in the most demanding environments. Mercury Racing backs its props with a one-year factory warranty, which also covers any and all damage done to the engine upon propeller failure.

The Bravo I FS has taken the bass, walleye, and multi species market by storm, in part because of the top end speed gains from its Pro Finish.

The only propeller not built exclusively by hand is the CNC Cleaver, which features our Lab Finish specifications for maximum top end speed.
