===== Owner's Responsibilities...

It is the owner's/ operator's responsibility to perform the necessary safety checks to ensure that all lubrication, cooling, maintenance and recommended practices are followed for safe, enjoyable operation.

Proper care and maintenance will only help ensure long service life from your Velvet Drive transmission.

==== General Information

1-1. Every Velvet Drive marine transmission is self-contained, having its own sump and hydraulic pump separate from the engine. The Rear driven pump affords assurance of positive lubrication.

1-2. The Velvet Drive In-Line hydraulic transmission is available in three (3) models with numerous final drive ratios suitable for inboard pleasure and work boats.

1-3. The Velvet Drive-" CR2 was designed specifically for twin screw applications. The counter rotating (CR) capability eliminates the need for opposite rotating engines.

1-4. The two (2) models of the V-Drive transmissions deliver the same horsepower ratings as the CR2. Gear or chain driven final drive will accommodate twin screw applications using same rotating engines.

1-5. The identification tag that appears on all Velvet Drive" transmissions is located on the top of the left-hand transmission mount and contains valuable information concerning the transmission. This information is as follows:

a. Model Number -- This appears below the words "Velvet Drive."
b. Ratio -- The gear ratio appears in the left-center of the identification tag.
c. Serial Number -- Appears at the right center under the model number.

16. Transfer the information on your identification tag to the Maintenance Record Chart on page 10 of this manual. Additionally. the color of the identification tag should be noted in the appropriate space and the date placed in operation.

1-7. The model number and serial number is required on all correspondence.

====== LAUNCH MAINTENANCE


2-1. The following maintenance should be performed after launching your boat to ensure optimum performance and life from your Velvet Drive" transmission.

CAUTION: Vibration, gear noise, loss of rpm and premature oil seal and bearing failure can be caused by misalignment of propeller shaft coupling and transmission output coupling flange.

2-2. Propeller shaft coupling flange and transmission output flange alignment is performed after launching of your boat, as well as any time your boat strikes a heavy object or after your boat has been hoisted or pulled from the water.

CAUTION: Remove attaching hardware from transmission output flange and propeller shaft coupling flange before removing boat from water and separate flanges.

2-3.  Check the alignment of the transmission output flange and propeller shaft coupling flange using the following procedure with boat in water:
a.   Disconnect the battery.
b.   Remove attaching hardware from coupling flanges.
c.   Check clearance around coupling flanges with .003 feeler gauge and flange pilot engaged.
d.   Rotate coupling flanges together one complete revolution, stopping every 90" to check clearance with .003 feeler gauge.
e.   Alignment is satisfactory when the transmission output flange and propeller shaft coupling flange with pilot seated are within 003 inch (.076 mm) of parallel.
f.  If alignment is unsatisfactory, an adjustment is required (see paragraph 2-4).
g.   When alignment is satisfactory, tighten attaching hardware.

2-4. Propeller and Output Shaft Adjustment

CAUTION: Do not lift or pry against transmission output flange or coupling to move engine.

This adjustment is accomplished at the boat motor and transmission mounts ONLY. This procedure should be accomplished by a skilled marine mechanic.
