Section 3
INSTALLATION RECOMMENDATIONS
The installation details contained herewith are basic guidelines to assist installation, due to great diversity of marine craft it is
impossible to give definitive instructions. Therefore Beta Marine can accept no responsibility for any damage or injury incurred
during the installation of a Beta Marine Engine whilst following these guidelines.
• All engines shall be placed within
an enclosure separated from living
quarters and installed so as to
minimise the risk of fires or spread
of fires as well as hazards from
toxic fumes, heat, noise or
vibrations in the living quarters.

ENGINE MOUNTING

Flexible Mount
To ensure vibration free operation, the
engine must be installed on substantial
beds, extending as far forward and aft
as possible and well braced to form an
integral part of the hull.
The engine must be installed as low as
possible on the flexible mount pillar
stud. This will limit vibration and
extend the life of the flexible mount. If
necessary, fit spacer blocks below the
mounts.
A flexible coupling should be fitted.
Flexible couplings do not accommodate
bad alignment. The mating faces of the
gearbox and tailshaft must be checked
for alignment, they must be parallel
and concentric to within 0.005"
(0.127mm).
ALIGNMENT
Alignment must be checked for
parallel (A) and concentric (B)
misalignment using a set of feeler
gauges. To obtain accurate alignment
the flexible mountings must be
adjusted until alignment is attained,
and the mountings must be locked in
position. Once mounts are tightened,
alignment must be re-checked.
Coupling can now be fitted in
accordance with instructions supplied
with coupling.
• Unless the engine is protected by a
cover or its own enclosure, exposed
moving or hot parts of the engine
that could cause personal injury
shall be effectively shielded.
WARNING
1. Do not set the engine feet high up
the flexible mount pillar stud. This
will cause excessive engine
movement and vibration. Pack
under the flexible mount with steel
shims securely bolted into the
engine bearer.
27
• Engine parts and accessories that
require frequent inspection and / or
servicing must be readily
accessible.
• The insulating materials inside
engine spaces shall be not
combustible.
2. The pillar stud on the flexible
mount is secured into position by
the lower locknut, do not forget to
tighten this. Also ensure that the
stud is not screwed too far through
the mounting body so that it can
touch the bearer. This will cause
vibration and knocking noises
which are very hard to find!!
