The Mercury F90 SeaPro is a legendary model in Mercury’s lineup, delivering 90HP from a compact and lightweight 2.1-liter four-cylinder engine. It is designed to offer maximum versatility – powerful enough for heavy-duty tasks and watersports, yet light enough for smaller boats. With 2064 cc displacement, the Mercury 90 outclasses competitors with smaller engines, providing up to 20% more torque at low RPM. This translates to quicker planing, especially on loaded boats. The EFI system and advanced ECM keep the motor optimally tuned even across varying altitudes and temperatures. The Mercury 90 is compatible with Mercury Active Trim – an automatic trim system that makes operation easier – and with SmartCraft digital gauges for full performance monitoring. Its weight (~165 kg for the long shaft model) is often less than equivalent 90HP engines from other brands, improving overall boat performance and reducing draft. A robust gearcase and optional Command Thrust give flexibility – the standard configuration is ideal for most recreational and light commercial crafts, while the CT version is great for pontoon and work boats that need extra thrust. With low vibration, minimal maintenance, and Mercury’s famed reliability, the 90 SeaPro remains a top choice for those who need a truly all-round 90HP outboard engine for commercial purposes.

Recommended Use: Suitable for mid-sized professional vessels ~5 – 7 m (fishing boats, utility launches, patrol craft) where a balance of power and agility is required.
Example Applications: Commercial fishing and aquaculture support, marine patrol and security boats, tour boats and charter RIBs that demand a 90HP engine delivering high efficiency and reliability under daily use.
