The Mercury 75 SeaPro is the commercial-grade version of Mercury’s 75HP outboard, engineered to withstand daily, long-hour operation. Delivering 75HP from a 2.1L inline four-cylinder engine, this motor provides robust low-end torque – crucial for pushing heavily loaded boats or towing tasks. As part of the SeaPro lineup, the Mercury 75 is deliberately under-stressed to deliver its 75HP with ease, significantly extending its durability. Components such as the gearset, mounts, and driveshaft are beefed up to commercial standards and tested to last three times longer than those in regular recreational models. Despite its rugged build, the engine retains hallmark Mercury advantages – an EFI fuel system for efficient combustion and reliable starting in all weather, along with relatively quiet operation (up to 15% quieter than competing engines in its class). Weighing around 165 kg (for XL shaft length), it comes exclusively with electric start and remote steering to suit its professional orientation. A heavy-duty Command Thrust gearcase with a large-diameter prop is standard, providing maximum thrust and authority to lift heavy loads onto plane and hold them there. If you need an outboard that can run tirelessly day in and day out, the Mercury 75 SeaPro is built for the job – featuring extended service intervals, rock-solid reliability, and fuel efficiency that help keep your operating costs low.
- Recommended Use: Ideal for commercial boats around 5 – 6 m in length (work boats, fishing vessels, service RIBs) that carry heavy loads or operate fully loaded on a regular basis.
- Example Applications: Water taxis, utility barges, rescue and patrol boats that demand reliable power and long-term durability from a 75HP engine.
