Use dipstick to determine fluid exact level.
Warm Fluid Level Check: The transmission should be at operating temperature [190 F (90 C)] maximum to
receive an accurate oil level reading.
Cold Fluid Level Check: To ease checking fluid level, the dipstick can be marked or scribed. First the procedure
for warm fluid level must be performed, then allow boat to sit overnight. Remove and wipe the dipstick clean.
Insert clean dipstick and mark the cold fluid level.

Checking Transmission Fluid

IMPORTANT: Engine must be run at 1500 RPM for 2 minutes immediately prior to
checking level.
NOTE: If engine is equipped with a Walter V-Drive Transmission, the transmission fluid level
should also be checked on the Velvet Drive Transmission. The two units do not share fluid.
It is also important to note that the units use a different type of fluid. Refer to "Maintenance
Aids" section found earlier in this manual, for fluid specifications.
1. Stop engine and check fluid level by pulling up on knob to remove dipstick. Fluid level
should be between "H" and "L" mark on gauge. If low, add specified fluid through dipstick
hole on transmission.
