INSTALLATION
FOREWORD
It is not the purpose of this section to advise boatyards and engine installers on
the generally well understood and well developed procedures for installation of
engines.
However
~
the following outline of general procedure· is included because
it is valuable in explaining the functions of each component, the reasons why
~
the
precautions to be watched and the relationship of the inst.allation to the operation
of the engine.
There· are details of the installation which should have a periodic
check and of which the operator should have a' thorough understanding to ensure
good operating conditions for the engine and correct procedure in servicing the
engine.
INSPECTION OF SHIPMENT
The engine is shipped from the factory mounted upon· heavy skids and properly
crated.
Accessory equipment is shipped in a separate small
box~
usually packed
with the engine crate. Immediately upon
arrival~
the shipment should be
inspect~d
for possible accidental damage in transit and for any possible shortage in parts
and equipment.
Before accepting any shipment from the transportation comppny
~
check with the packing list and if any shortage or damage is
noted~
file claim with
the agent before accepting shipment, reporting same to the shipper.
FOUNDATION FOR ENGINE
A good engine bed contributes much towards the satisfactory operation of the
engine.
The engine bed must be of rigid construction and neither deflect or twist
. when subjected to the engine weight or the position the boat mCl,Y have to take under
the effects of rough seas.
The bed must not only support the engine firmly in the
exact position but must keep the engine within one or two thousandths of an inch of
this· position at all times.
It has to withstand the forward push of the propeller
which is applied to the propeller
shaft~
to the thrust washer bearing in the engine
and finally to the engine bolts and
engin~
bed.
In
fiberglas
hulls~
we recommend that similar wooden stringers as in wooden hulls
be formed and
fitted~
then glassed to the hull securely.
This .allows hanger bolts
to be installed firmly
in
wood~
thus reducing noise and transmitted vibration.
The temptation to install the engine on a pair of fiberglas "angle irons" should be
resisted.
Such construction will allow engine vibrations to pass through to the
hull.
Flexible mounts require a firm foundation against which to react if they are
to do their job.
When possible, follow bed design" A" and avoid bed design
