Suzuki Df6 Service Manual ◎ <Confirmed>

Changing the gear oil seems simple, but the manual shows you the exact fill procedure (from the lower hole until it weeps out the upper hole), correct oil viscosity (Suzuki Marine gear oil or SAE 90), and o-ring replacement for the fill/drain screws.

The part number covers most DF6 models from 1998 to approximately 2014. If you have a DF6A (2015+), you need a different manual (99500-06410-01E). Always confirm your engine serial number before purchasing. suzuki df6 service manual
