36 Twin Vee with Twin Yamaha 300 HP

Sharrow Marine conducted tests on a 36’ Twin Vee with twin Yamaha 300 hp outboard engines. Data was collected with the original 14.5” x 15” Stainless-Steel 4-Blade propellers and 15.5” x 15.9” Sharrow Marine propellers with TRUE ADVANCE™. The data indicates that the Sharrow Marine propellers delivered up to 32% improved fuel efficiency at cruise, achieved a significantly more efficient Advance Rate across the entire RPM range, and produced up to 7.7 NMPH higher speed at equivalent cruising RPMs, while reaching slightly higher top end speed versus the original the traditional propellers.
