CHANGING THE GEARBOX OIL
1. The oil can be changed via the drain plug at the bottom
of the box or sucked out with a hand pump via the filler
plug or dipstick hole.
2. Run the gearbox for 10 minutes to warm up the oil.
3. Switch off the engine, remove the dipstick and begin
to drain oil from the gearbox and cooling system.
The drain plug is located on aft starboard side of the
gearbox on most models.
4. Allow to drain, before refilling the gearbox with new
oil as recommended.
5. Run the engine to allow oil to circulate, then stop and
allow the oil to settle. Re-check the oil level and top
up if necessary.
6. Ensure dipstick and cap are firmly secured and check
for oil leaks, especially around the output shaft oil seal
and gasket sealing surfaces.
NB: ATF is Automatic Transmission Fluid.
