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

Important Information
Shift Control and Cables
CAUTION
Shift control and shift cable must position transmission shift lever exactly as stated
in this manual, or transmission, as a result of improper shift lever positioning, will
not be covered by Velvet Drive Warranty.
IMPORTANT: Velvet Drive Warranty is jeopardized if the shift lever poppet ball or
spring is permanently removed, or if shift lever is repositioned or changed in any
manner.
Remote control used must position transmission shift lever over the letter “F” embossed on
transmission case when remote control is placed in forward gear position. Transmission fail-
ure will occur if transmission shift lever is positioned over the letter “R” and the wrong rota-
tion propeller is used to propel boat forward.
Remote control also must provide a total shift cable travel (at transmission end) of at least
2-3/4
in. (70 mm). This is necessary to position transmission shift lever fully in the forward
and reverse gear positions. Insufficient shift cable travel will cause transmission to slip and
eventually fail.
