VELVET DRIVE 5000A DOWN ANGLE TRANSMISSION
SERVICE MANUAL NUMBER 23
Important Information
Engine
Engine rotation is indicated on engine specifications and serial number decal on the engine.
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
12
° of the water line.
Transmission
Transmission gear ratio is marked on transmission identification plate, which is located on
the port (left) side of transmission. Transmission rotation is described when viewed from the
rear of transmission with transmission in forward gear selector position.

DO NOT start or crank engine without fluid in transmission.
Use only Dexron III ATF 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 here will pre-
vent 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.
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.
