SOLAS Lab finished propellers are blue-printed propellers that go through a 40-point inspection. The end result is a perfectly balanced propeller with flawlessly matched cupping across every blade and a custom blade thickness. The enemy of every boat and propeller is drag, lab finished propellers are finely tuned to eliminate drag.
The pro series has additional polishing and blade thinning to create sharper blades that will cut through the water better and raise rpms to gain more top speed. The longer barrel improves performance and decreases cavitation by allowing air and water created from the blades to easily flow behind the propeller and decrease drag. With the pro series adjustable vents, you can fine tune the performance and decrease planing time. The camber, or arch of the blade is more aggressive on the pro series which allows it to push back more water and reach higher speeds.
All of this combined means there will be consistency in RPM when running on a multi-engine setup, and in most applications the Pro Series propeller will deliver higher top-end speed than a Standard Finish propeller.
