VELVET DRIVE 5000V V-DRIVE TRANSMISSION SERVICE MANUAL NUMBER 23
Page 8C-4 90-861326--1 MARCH 1999
Transmission
Transmission gear ratio (in forward gear) is marked on transmission identification plate,
which is located on the port (left) side of transmission.
1. DO NOT start or crank engine without fluid in transmission.
2. Use only recommended fluid in transmission.
3. Except in an emergency, never shift transmission at engine speeds above 1000 RPM.
4. Free wheeling of one propeller (in a twin engine boat), at trolling speeds, will not cause
damage to the transmission; however, boat operation above trolling speed should be
avoided. Be sure proper fluid level exists before free wheeling propeller.
5. DO NOT paint shift lever poppet ball and spring. An accumulation of paint here will pre-
vent proper action of the detent.
6. Always replace oil cooler and hoses after a transmission failure or prior to installing a
new or rebuilt transmission. Metallic particles from a failure tend to collect in the cooler
and hoses and will gradually flow back into the fluid system and damage transmission.
7. Always use specified oil cooler, hoses and fittings. Hoses must be at least 13/32 in. (10.5
mm) I.D. Oil cooler, hoses and fittings must be sufficient size to maintain transmission
fluid (in sump) at 140-190°F (60-88°C).
Propeller
Propeller rotation is described when observed from the rear of the boat (stern) looking for-
ward (bow end). The term “left-hand” (LH) refers to rotation in the counterclockwise (CCW)
direction. The term “right-hand” (RH) refers to rotation in the clockwise (CW) direction. A LH
propeller will move the boat forward when rotated counterclockwise. A RH propeller will
move the boat forward when rotated clockwise. Propeller rotation is not necessarily the
same as engine rotation.
Transmission Shift Lever
The lever has three holes as illustrated following.
