Choosing a marine gearbox ratio starts with the engine torque curve and the speed required at the surface drive. For a surface-piercing propeller, the final choice must also suit the propeller geometry, hull resistance and operating immersion. Engine horsepower alone cannot establish the right ratio
Read MoreVerified by 32 sets of pool calibration data and 27 global vessel sea trials, standardized mass-produced surface drive systems are no longer niche refitting accessories, but universal next-generation high-speed vessel propulsion solutions. Compatible with diesel, gasoline and hybrid power units, TSD propulsion covers patrol, rescue, yacht and recreational vessel scenarios. Future marine propulsion competition will break horsepower involution, focusing on long-term durability, extreme sea condition stability and full-lifecycle operational costs. This is also the core track for domestic marine propulsion manufacturers to achieve global overtaking.
