5. Fill crankcase as outlined under "Filling Engine
Crankcase", following, and check for oil leaks while
engine is running.
Filling Engine Crankcase
The engine crankcase capacity is approximately 5 qts. with a
new, dry oil filter. Because of the effect the installed angle
of the engine has on the oil level, the following procedure
must be followed and the boat must be at rest in the water.
1. Pour oil into engine thru oil fill opening in rocker arm
cover until level comes up to full mark on dipstick.
2. Start engine and run at idle speed for 5 minutes.
3. Stop engine and, after approximately 1 minute, check
level on dipstick.
4. Add quantity of oil required to bring level up to full
mark.
TRANSMISSION
Description Reverse Gear Section
The transmission consists of a planetary gear set, a forward
clutch, a reverse clutch, an oil pump and a pressure regulator
and rotary control valve. All are contained in a cast iron
housing (along with necessary shafts and connectors) to
provide forward, reverse and neutral operation.
A direct drive ratio is used for all forward operation. In
reverse, speed of the output shaft is equal to input shaft
speed, but in the opposite direction. Helical gearing is used
to provide operation more quiet than can be obtained with
spur gearing.
Shifting is accomplished by fore and aft movement of the
shift lever. This movement rotates control valve and directs
oil under controlled pressure to required channels.
Oil pressure is provided by the crescent type pump and drive
gear which is keyed to the drive shaft. Pump operates at
transmission input speed to provide screened oil to the
pressure regulator.
From the regulator valve, oil is directed through proper
circuits to bushings and anti-friction bearings which require
lubrication. A flow of lubricant is present at the required
parts whenever the front pump is turning, and it should be
noted that supply is positive in forward, neutral and reverse
conditions.
The unit has seals to prevent escape of oil.
Both input and output shafts are coaxial, with input shaft
splined for installation of a drive damper, and output shaft
splined for connecting to the coupling.
Precautions
1. Oil cooler must be properly connected to transmission
before engine is cranked or started. Failure to properly
connect oil cooler will cause forward clutch piston to
blow out from over-pressurization.
2. Change oil and clean oil screen once each season.
3. Check oil level at operating temperature.
4. Use clean containers for handling transmission fluid.
5. Fill transmission prior to starting engine.
6. Check oil level immediately after engine is shut off.
7. Use recommended automatic transmission fluids Type
"A" Suffix "A" or new Dexron fluid.
8. Flush cooler and cooler lines after a transmission failure
and prior to installing a new or rebuilt transmission.
9. Check engine alignment each time a transmission is
replaced in boat.
10. Check shift linkage adjustment to insure that
transmission shift lever is being positioned so that
springloaded ball enters chamfered hole inside of shift
lever in each selected position.
11. Check oil pressure and temperature when transmission
functions indicate that a problem exists.
12. Always check pump rotation prior to assembling
transmission to engine to ensure that pump is properly
indexed for engine rotation.
13. Except in emergency, do not shift at engine speeds
above 1200 RPM.
14. Never remove oil cooler lines or use smaller than
recommended 13/32" (10mm) diameter cooler lines
when operating transmission.
15. Do not permit propeller shaft to rotate when
transmission is inoperative. Propeller shaft rotation
could be caused by towing, sailing or operation of
second engine which could move the boat through the
water and cause propeller to "windmill".
16. (A thread sealant) must be used on pipe threaded
hydraulic connections, to prevent hydraulic fluid from
leaking.
Lubrication Recommendations
The properties of the oil used in the transmission are
extremely important to the proper function of the hydraulic
system. Therefore, it is necessary that the recommended oil,
automatic transmission fluid (ATF), Type "A", Suffix "A",
be used. This fluid is currently known as "Dexron".
Procedure for Filling Transmission with Oil
When filling transmission, add oil until it reaches full mark
on dipstick. Quantity of oil depends upon angle of
installation, but information to serve as a guide on possible
amount needed may be found in chart following. Unit should
be turned over at engine idle speed for a short time in order
to fill all circuits, including cooler and cooler piping.
