The ferry boat Emerald Isle , which operates between the port town of Charlevoix, Michigan, and Beaver Island, in northern Lake Michigan, saved 8,500 gallons of fuel per engine the next season after having their props reworked and properly tuned by Mitch at Holand Propellers using the Prop Scan system.

Mitch from Holland Propellers states that the fuel savings with a properly tuned propeller will routinely average between 15 to 20%. Wow!
