Engine Mounting - Beta Marine Beta 14 Installation Manual

ENGINE MOUNTING

To ensure vibration free operation, the engine must be
installed and correctly aligned on substantial engine
bearers, extending as far forward and aft as possible, well
braced and securely fastened 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. To assist with engine
replacement we offer 'Special Engine Feet' manufactured
to your dimensions, as an optional extra to suit your
existing engine bearers and shaft alignment / installation.
WARNING!
• Do not set the engine feet high up the flexible mount
pillar stud. This will cause excessive engine movement
and vibration. Pack steel shims under the flexible
mount and ensure that the flexible mounting is
securely bolted to the engine bearer.

ENGINE INSTALLATION AT AN ANGLE
Beta Marine propulsion engines can be installed at angles
up to a maximum of 15° flywheel up or flywheel down
when static, and can be run at up to 25° when heeling.
However if you are considering installing above 12° please
contact Beta Marine or alternatively consider the 7° down
angle gearbox. When our engines are installed at varying
angles of inclination the normal markings on the dipstick

4 Engine Mount
• 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! If the flexible mounting is
too far offset then the loading on the flexible mounting
will cause premature failure, modifications are needed.
NOT Recommended
Positioning too high on the
pillar stud - requires shims
should be disregarded. It is probably better to totally drain
the sump, and completely refill the engine sump with the
recommended quantity / volume of lubricating oil - noting
its position on the dipstick - and then marking the dipstick
accordingly (don't forget to replace the oil filter). If in
doubt ask Beta Marine!
