Under 10HP Complete Outboard Engines

Complete Outboard Engines that are Under 10 Horsepower

While manufacturers of outboard motors may change their designs year after year, the horsepower category remains the same. There are a wide range of four-stroke outboard boat engines that vary from 2 to 10 HP. The number of cylinders, weight, water displacement, and full throttle range are the main differences between each engine. Each unit either uses diesel or gas for fuel.

• An outboard model with 2 to 6 HP has one cylinder, whereas the 8 to 10 HP motors have two.
• The shaft size of each unit is available in either 15, 20, or 25 inches.
• The water displacement and RPM differ between models.

• Honda created the BF2.3 with a water displacement of 57.2 CCs and an RPM of 5,000 to 6000.
• Mercury made the 2.5MC with a water displacement of 85.5 CCs and an RPM of 4,500 to 5,500.
• Suzuki designed the DF2.5 with a water displacement of 68 CCs and an RPM of 5,250 to 5,750.
• Each outboard motor weighs approximately 30 pounds.

• Honda created the BF4DHSHNA with a water displacement of 127 CCs and an RPM of 4,500 to 5,500.
• Mercury developed the 4MH with a water displacement of 123 CCs and an RPM of 4,500 to 5,500.
• Yamaha designed the F4LMHA with a water displacement of 139 CCs and an RPM of 4,000 to 5,000.
