Description

The Yamaha Pro60hp 2-stroke outboard is a lightweight, durable, and highly responsive engine favored for both commercial fishing and leisure. Offering a strong power-to-weight ratio, it features a 3-cylinder, 849cc displacement block and typically relies on a manual or pre-mix oil system

Key Specifications

Engine Type: 2-Cylinder or 3-Cylinder 2-stroke (depending on the specific model/year)

Displacement: 849cc – 896cc

Full Throttle RPM: 4,500 ~ 5,500 RPM

Fuel Consumption: ~25.5 liters per hour at wide-open throttle

Lubrication: Pre-mixed fuel (or Autolube/oil injection system on select FETO/Autolube models)

Weight: ~97 kg (213 lbs) to 105 kg, making it significantly lighter than 4-stroke equivalents

Advantages & Common Considerations

Performance: Provides instant, snappy hole-shot acceleration and is easier to maintain mechanically compared to complex 4-strokes.

Reliability: Built to withstand harsh commercial and passenger vessel environments.

Fuel/Oil: Requires mixing two-stroke marine oil with your gasoline (unless equipped with the functioning “Autolube” oil-injection pump)

Noise & Smoke: Like all 2-strokes, it produces more exhaust smoke at idle and is noisier than 4-stroke engines

Maintenance Essentials

Fuel Mixing Ratio: Usually requires a standard 50:1 gas-to-oil mixture for optimal engine longevity.

Water Pump Impeller: It is recommended to replace the water pump impeller every 100 hours or once a year.

Carbon Buildup: 2-strokes are prone to carbon buildup. Running high-quality marine engine decarburizers or fuel additives helps keep the pistons and rings free from deposits
