General Information
Engine Rotation
Engine rotation is described when observed from the rear of the engine (transmission end)
looking forward (water pump end). All Mercury MerCruiser engines are left hand (LH)
rotation. Propeller rotation is not necessarily the same as engine rotation; See Section 2
—Transmission and Drive Line.

the proper weight rating when lifting the engine.

Engine Oil Dipstick Relocation
Some models are equipped with an oil dipstick in the port and starboard dipstick tubes. If
only one dipstick is present and the engine is equipped with two dipstick tubes, you may
relocate the oil dipstick.

Engine Compartment Construction
! WARNING
Improper boat design and construction may result in serious injury or death. Adhere to
all applicable marine regulations (United States Coast Guard [USCG], European Union–
Recreational Craft Directive [EU‑RCD], etc.) and the standards they reference (American
Boat and Yacht Council [ABYC], Society of Automotive Engineers [SAE], International
Standards Organization [ISO], etc.) when designing and constructing the boat and other
components, such as the engine compartment, fuel delivery system, or exhaust system.
Engine Compartment Ventilation
See Section 4—Air Intake System.
Engine Compartment Seams
NOTICE
Water that runs onto the air intake may enter the engine and cause serious internal engine
damage. Design engine compartments so water cannot run onto the air intake or flame
arrestor.
Exercise care in the design and construction of the engine compartment. Seams must be
located so that rain water is directed away from the air intake system and electrical system.
Clearance
IMPORTANT: The engine compartment must provide a minimum of 13 mm (½ in.)
clearance between the boat and any component on the engine (i.e. exhaust manifold,
elbow, oil pan, transmission case, etc.). This allows for engine mount deflection during
operation.
Engine Bed Requirements
The engine bed (i.e. stringers) must be designed to support the G‑forces imposed by the
engine during the most severe duty. The bed must also handle the torque produced by the
engine and the thrust generated by the propeller. Deflection of the engine bed could stress
the engine components, causing possible engine misalignment and transmission failure.
The proper design of the engine bed varies considerably from one boat design to the next.
Therefore, Mercury MerCruiser makes no attempt to provide detailed engine bed design
requirements to cover all possible applications. The proper design of the engine bed is left
to the boat manufacturer. The following general guidelines are provided:
• The engine bed must be firmly affixed to the boat and should be made as large as
possible to distribute the load evenly. Reinforcements should be used where
necessary. Mount pad locations should be as large as possible.
• The engine mounts are designed for the industry standard 572 mm (22½ in.) stringer
widths (center to center), but can accommodate widths up to 610 mm (24 in.).
• The engine bed must position the engine so that a minimum 6 mm (¼ in.) of up and
down adjustment exists on all four mounts after performing the final engine alignment.
This is necessary to allow for realignment in the future. Engine mount isolators will
compress slightly over time.
• The front and rear mount locations on the engine bed should be in parallel planes. This
can be checked by tying a string from the left front mount location to the right rear mount
location and another string from the right front to the left rear. The strings should just
touch were they cross.
Page 3A-4
90-863758070 APRIL 2008
Engine
•
The engine mounts must rest squarely on the engine bed so that the rubber isolator is
not preloaded in one direction or the other. Preloading the engine mount will cause
increased vibration.

• The metal ring must not contact the mount base on the front mount.

Typical front mount
a - Metal ring
•
b - Mount base
Engine mounts have provisions for 10 mm (3/8 in.) fasteners for securing mounts to
the engine bed. Fasteners should be selected as appropriate for the type of engine bed
material being used. The slot in front engine mounts should face forward. Do not install
fasteners at an angle.
Serviceability
All engines require maintenance, and some require service repair within the life of the
product. Consider serviceability when designing the engine compartment.
In addition to customer and dealer satisfaction, consider the implications of serviceability
with respect to our warranty policy. The Mercury MerCruiser warranty policy states, in part,
that reasonable access must be provided to the product for warranty service. Refer to the
warranty policy in the appropriate Operation, Maintenance, and Warranty Manuals. It states
that removal or replacement of the boat partitions or material because of boat design for
necessary access to the product is not covered. Consider serviceability when designing
the boat and engine compartment to avoid these types of issues.
Consider all engines options used in a boat when designing the engine compartment. The
engine size differences between some of the models as well as differences in service point
locations may have a major effect on serviceability.

The following is a list of the major service points to consider when designing the engine
compartment. Typical illustrations are shown to assist you in identifying these locations.
These are typical views and may not accurately represent the model that you are working
with. The specific engines, along with their installation drawings and the appropriate
Operation, Maintenance, and Warranty Manual, should be used when doing the actual
design work.

Engine Alignment
Proper alignment between the transmission, and the propeller shaft is essential to minimize
noise, vibration, and power loss and to avoid overstressing the transmission and drive line
components. Perform a preliminary alignment at engine installation. The final alignment
must be done after the boat is in the water to compensate for any deflection in the hull. On
applications with a rigid propeller shaft coupler, dsconnect the coupler from the
transmission for shipment. Check the alignment with the boat in the water. The requirement
for checking the alignment should be clearly communicated to your dealers, along with an
understanding as to who is financially responsible.
90-863758070 APRIL 2008
Page 3A-19
Engine
The complete alignment procedure is outlined in the installation manuals. Important
elements of this process include:
• Align the engine to position the pilot on the propeller shaft coupler into the recess in
the transmission output flange so that the mating surfaces of the flange and the coupler
are parallel within 0.07 mm (0.003 in.).
7534
•
Check alignment by holding the flange and the coupler together and checking at 90°
intervals with a feeler gauge. The coupler should be rotated 180° and alignment
rechecked to ensure that the coupler and flange are in alignment.

Draining the Seawater System
! CAUTION
Water can enter the bilge when the drain system is open, damaging the engine or causing
the boat to sink. Remove the boat from the water or close the seacock, disconnect and
plug the seawater inlet hose, and ensure the bilge pump is operational before draining.
Do not operate the engine with the drain system open.
IMPORTANT: Only drain the seawater section of the closed‑cooling system.
IMPORTANT: The boat must be as level as possible to ensure complete draining of the
cooling system.
Your power package is equipped with a drain system. Refer to Drain System
Identification to determine which instructions apply to your power package.
IMPORTANT: The engine must not be operating at any point during the draining procedure.
IMPORTANT: Mercury MerCruiser requires that propylene glycol antifreeze, mixed to the
manufacturer's instructions, be used in the seawater section of the cooling system for
freezing temperatures or extended storage. Make sure that the propylene glycol antifreeze
contains a rust inhibitor and is recommended for use in marine engines. Be certain to follow
the propylene glycol manufacturer's recommendations.
