For some stepped vee-bottom hulls, adding the lab finish will improve the ride and efficiency. For multiengine center consoles, the Lab Finished Rev 4 can provide a needed gain in rpm thanks to the thinner blades. Compared to a Pro Finished Rev 4 XP, the Lab Finish will add 100 to 150 rpm at WOT. The Lab Finish is the ultimate Rev 4 for those who seek the highest top-end speeds.


  • Our lab-finished Rev 4 has thinner blades, which create gains in rpm at wide-open throttle.
  • This finish allows the propeller to spool up fast for improved acceleration.
