Proper lubrication is essential for your Suzuki outboard engine’s smooth operation and longevity. Without proper gear oil, the gears in your engine can wear down quickly and cause major damage. Due to this, you should understand the appropriate gear lube capacity for your specific Suzuki outboard model.

Suzuki outboard gear oil capacities vary by model, from less than 0.3 liters (0.3 quarts) for smaller engines like the DF4–DF6, up to more than 2.0 liters (2.1 quarts) for larger V6 and V8 engines. Use the chart above to find your exact capacity.

At PartsVu, we understand the importance of maintaining your outboard engine and keeping it running at peak performance. That’s why we have compiled a comprehensive gear lube capacity chart for Suzuki outboard engines. This chart includes information on various models and their corresponding gear oil capacities.

Specifications & Benefits of OEM Suzuki Gear Oil

  • Meets/exceeds FC-W marine standards
  • Formulated for anti-foaming and water separation (important for marine use)
  • Superior corrosion resistance vs. automotive gear oils
  • Designed for high-load, high-RPM outboard operation

Maintenance Guidance

“Suzuki recommends changing your gear oil every 100 hours or annually, whichever comes first. For heavy use (extended trolling, saltwater operation, or wide-open throttle running), service may be required more frequently.”

Frequently Asked Questions


What is the capacity of Suzuki outboard gear oil?

Gear oil capacity ranges from about 0.3 liters for small engines to over 2 liters for larger V6/V8 models. Use the dropdown chart to confirm your exact capacity.

How often should I change my Suzuki outboard gear oil?

Every 100 hours or annually; sooner if you notice milky oil (a sign of water intrusion) or metal shavings.

What kind of gear oil should I use?

Always use OEM Suzuki gear oil or FC-W certified marine gear oils to ensure protection, warranty compliance, and proper viscosity under load.

Can I use automotive gear oil in my Suzuki outboard?

Automotive gear oils are not designed for the marine environment. Marine gear oil is specifically blended for water resistance, anti-foaming, and high-load conditions.

What are symptoms of bad gear oil?

Milky appearance (water intrusion), burnt smell, or metal flakes are all warning signs that oil needs immediate replacement and the system should be inspected.
