Engine mounting
Installation angles
The engine is intended to be installed so that the
cylinders are vertical, when viewed from ahead or
astern (A).
In service, however, the sump tted as standard on the
M65 and as an option on the M85T (B) may operate
continuously at a heel angle of 20O, and intermittently
(i.e. for up to 15 seconds at a time) at an angle of
25O.
A high inclination sump tted as standard on the M85T,
and as an option on the M65, allows an operating
heel angle of 25Ocontinuously, and intermittently up
to 35O(C).

Installation angles (continued)
The engine is suitable for installation so that in side
view the crankshaft is horizontal, or ‘ywheel down’ to
a maximum of 17O(A).
An allowance has been made for an additional 3Orise
to occur in service, when climbing waves or starting
to plane.
Engine mounting brackets
The standard brackets provide mounting points which
are 35mm below, and parallel with, the crankshaft
centre line (B1).
The brackets may be used to mount the engine
directly on to engine bearers, but for all applications it
is recommended that exible engine mounts are used
(B2).
Engine mounting brackets are available for transverse
mounting centres of either 460mm or 550mm (C1).
In both cases the longitudinal mounting centres are
654mm (C2).

Alignment of engine
The following method may be used:-
Place the engine on the bearers in the hull (A) and
adjust its position until it is aligned to the propeller
shaft, both when viewed from above and from the
side.
Drill 4 holes in the engine bearers in the positions
shown (B1, B2, B3, B4). Bolt the mounts to the
bearers, but do not fully tighten (if the mount has a
cross slot and a longitudinal slot, bolt through the
longitudinal slot).
Carry out any ne side-to-side adjustments necessary
by allowing the mount to rotate slightly about the bolts
just tted (C).
Then drill the remaining 4 holes for the engine mounts
through the centres of the slots. Fit bolts and tighten
all around.
The mounts are provided with studs to provide easy
height adjustment, but applications where there
may be heavy impacts should use shims for height
adjustment.

Engine bearers
Many types of engine bearer have been found to be
satisfactory in service, including:-
Foam lled f.r.p. with metal plates bonded in, which
are drilled and tapped during engine installation.
Plywood, with epoxy or f.r.p. coating.
Steel channels, attached to bulkheads fore and aft.
Although it is common for the engine mountings to
sit on top of the bearers, in some cases the bearers
are spaced so that the engine ts between the inner
faces, supported by stirrup brackets (A).
Design guidelines
The following rules apply to all bearers:-
The bearers should be capable of supporting a static
load of 5 to 8 times the weight of the engine and
gearbox, to cater for the effects of rough seas.
Cross connections should be arranged to give lateral
rigidity, in order to maintain shaft alignment and to
prevent twisting and racking forces being applied to
the engine.
If the bearers are exible, unwanted vibrations may
be set up in the hull, so the assembly should be made
as stiff as possible.
Close spacing
To enable minimum shaft centre distances to be
achieved in a twin installation, a common centre
bearer supporting the inner mountings of both engines
is sometimes used as shown in (B). By this method
shaft centres down to 630mm may be adopted.
The shaft centres could be reduced further, but this
would result in the engine accessibility becoming very
restricted, and it would be impossible to carry out
service operations.
It should be noted that if minimum shaft centres are to
be adopted, space must be left in front of and behind
the engine to provide access. A minimum clearance
on all sides will mean that the engine cannot be
serviced!
