VELVET DRIVE IN-LINE AND V-DRIVE TRANSMISSION
Important Information
Shift Control and Cables
SERVICE MANUAL NUMBER 24
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 man-
ner.
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
failure will occur if transmission shift lever is positioned over the letter “R” and the wrong
rotation propeller is used to propel boat forward.
Remote control must provide shift cable travel (at transmission) of at least 2-3/4 in. (70 mm)
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.
Engine
Engine rotation is indicated on engine specifications and serial number decal on flame
arrestor cover. Engine rotation is described when observed from the rear of the engine
(transmission end) looking forward (water pump end).
Installed angle of MIE inboard transmission and engine should not exceed a maximum of
18
° of the water line.
Transmission
Transmission gear ratio (in forward gear) is marked on transmission identification plate,
which is located on the port (left) side of transmission. Transmission output shaft rotation
and propeller rotation required is indicated on a decal on transmission case. Transmission
rotation is described when viewed from the rear of transmission with transmission in forward
gear selector position.
On MIE engines equipped with in-line transmissions having 1:1 gear ratio, transmission out-
put shaft rotation is the same as engine rotation with transmission in forward gear. Engine
rotation is LH (CCW), so a LH propeller is required.

4.
DO NOT start or crank engine without fluid in transmission.
Use only recommended fluid in transmission.
Except in an emergency, never shift transmission at engine speeds above 1000 rpm.
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.

6.
DO NOT paint shift lever poppet ball and spring. An accumulation of paint will prevent
proper action of the detent.
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.
