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 clean the dipstick.
Insert clean dipstick and mark the cold fluid level.
