Engine oil should be changed after the initial 15 hours or operation and at each 200 hours of operation thereafter.
Run the engine until normal operating temperature is reached. Shut down engine and allow oil to return to sump
for five to ten minutes. In most installations it will not be possible to drain sump by removing plug which is located
at bottom of oil pan, for clearance to bilge of hull will be limited. A low-cost, suction type, hand operated sump
pump is required. Available as an extra cost option is a Lehman approved, permanently mounted hand pump. This
can be connected to the sump lug

Remove the dip-stick tube and insert suction
hose of pump, working same towards lower portion of sump. (Some operators find it advantageous to use a length
of copper tubing to assure reaching low section of sump. Pump oil into container and dispose of same ashore.
Replace vent cap on sump. Refill crankcase to
“full”
mark on dipstick. Run engine for several minutes, shut down
and recheck oil level. If required, add sufficient oil to bring up to full mark.
Lube oil filter element should be replaced at each oil change. the disposable element is simply unscrewed from its
base by turning counter- clockwise on naturally aspirated engines it is possible to rotate the oil filter, or remove it
from its bracket, thus minimizing the risk of oil spillage. Position a one-quart or larger container under filter before
removal to catch oil from spilling into bilge. A new element is simply screwed onto the base with medium hand
tightness. Under no circumstances should a wrench or excess pressure be used. When next starting engine, check
filter for possible leaks or seepage, and tighten only sufficiently to prevent same.

Transmission
As there is such a wide variety of transmissions available with Lehman diesels, it is not practical to cover all
installations in this manual. However, due to the popularity of the Borg Warner,
and Twin Disc
transmissions, the following information is offered for those models.
BORG WARNER
No attempt is made herein to instruct in the installation of engine in the boat. The prudent boat owner or operator
will, before initially starting engine, check
alignment, operate clutch control to make certain that lever
fully travels to the full ahead or full reverse positions, that neutral position may easily and quickly be found and of
course check oil level.
The transmission is a self-contained, sealed unit with independent lubrication system. No external adjustments of
any kind are required. A built-in oil pump supplies the required hydraulic pressure
to provide effortless shifting and
assures an adequate supply of lubricant to all moving parts. An oil cooler is provided in order to maintain proper
oil temperature which should not exceed
190
Automatic transmission fluid type A, suffix A is recommended for lubrication*. Or, if desired, “Dexron” type fluid
maybe used. Before starting engine fill transmission
to
the full mark on the dipstick. Run engine for a minute or
two at low speed (in order to fill oil lines, cooler, etc.) Then shut off engine and check
oil level. Add sufficient oil to
bring up to full mark. Transmission oil level should be checked each time the oil level in engine is checked. Change
oil every
200
hours of operation or at least once each season under normal conditions however, number of hours
may vary depending upon severity and conditions of service WARNER drain plug is a large “hex” plug located near
bottom right side. Removal of this plug and a small plug on the bottom of the reduction housing will completely
drain the transmission. On some models the cooler return hose may be fed into the plug at the bottom of the
transmission, In these instances, remove the hose and rotate the brass elbow as required for draining.
