his chapter will serve as a general introduction to the
engine assembly and its associated components. Specific
information on part identifying, operating and maintaining
your engine is found in the manufacturer’s OEM man-
ual. Our discussions will touch on the following items:
Engine / Transmission
Engine Fluids
Engine Operations
Exhaust
Maintenance
11.1 Engine / Transmission
Your Hunter sailboat comes equipped with auxiliary
power, a diesel engine. The standard engine is a 29HP
shaft drive model with an optional 40HP saildrive model
available. Proper attention to and maintenance of your
engine will assure you of many hours of pleasurable, safe
boating, and will prevent unnecessary engine problems.
You must, therefore, become a student of your engine
and be thoroughly familiar with all aspects of proper
operations as outlined in the manufacturer’s OEM manu-
als. In addition, follow their recommended maintenance
and warranty schedule. Engine abuse or improper main-
tenance may adversely affect any possible claims made
under the independent warranty provided by the engine
manufacturer.
NOTE: All illustrations in this manual depict the 40HP engine.
11.1.1 Engine
The engine can be accessed through multiple locations,
depending on the desired angle of approach. Points of
access are from the aft cabin (lift up engine cover and
remove - left side Fig. 11.1), galley (remove door with
push button latch - right side Fig. 11.1), companionway
(lift up hinged step - left side Fig. 11.2), and head (remove
door with push button latch - right side Fig. 11.2). As a
visual point of reference, each point of access picture (of
the 40HP engine) is accompanied by a illustration with
the same orientation. In addition, see Figure 11.3 for an
profile illustration of the 29HP engine layout.

•
In general, the engine assembly is often referred to as 2
associated components: the engine and the marine gear
or transmission. The 29HP engine propulsion assembly
includes the straight shaft that bolts to the marine gear.
The 40HP engine propulsion assembly includes a sail
drive which incorporates the marine gear in the one
assembly.
The transmission has a reduction gear which drives
the propeller at a slower rotation speed than that of the
engine. For the 29HP engine, the propeller shaft is
mounted to the transmission and passes through the hull
within the stuffing box (see Underwater Gear chapter of
this manual for a description of the stuffing box). For the
40HP engine, the sail drive passes through the hull and
is protected from water breach with gaskets.
11.1.3 Nameplates
A nameplate is attached to the rocker arm cover (top of
engine) and provides the following information:
model
gear model
continuous power (kw)
Speed of prop shaft
fuel stop power (kw)
engine number
manufacturing date
A nameplate is attached to the transmission and sail drive
and provides the following information:
model
gear ratio
oil
manufacturer’s number
This information will be important when communicating
with the engine manufacturer or Marlow-Hunter regarding
warranty, parts and service
DANGER
! !
When near the engine or any area where mechanical
equipment is located, always be aware of moving
parts or components. Death or dismemberment may
result if entangled in moving machinery.
CAUTION
