What this video covers

Setting a higher pitch on a PYI MaxProp for reverse gear than for forward gear improves maneuverability when backing a catamaran into a slip.0:23 At low engine RPMs typical of harbor maneuvering, the engine possesses excess power that a higher pitch can effectively utilize to provide more thrust.0:59 While increasing forward pitch beyond the engine's rated RPM capacity risks overloading the engine at wide-open throttle, reverse gear operation rarely reaches these high-load conditions.1:11 Increasing forward pitch can improve fuel efficiency at cruising speeds, though increasing propeller diameter remains a more inherently efficient method for improving performance if hull clearance allows.1:29 Adjusting the reverse pitch to take a larger bite provides better control during low-speed docking maneuvers without compromising engine health.0:59
