3 - Installation
1. Ventilation
All internal combustion engines radiate heat and require cool, clean air to aid
complete combustion.
Please ensure that adequate engine room ventilation is provided, by fitting at least
two vents of an aperture of not less than 10,000 mm
2
each, (16 in
2
).
An allowance must be made for any grills or louvers or bends placed in the airflows
and generally an increase of 25% in area is sufficient to overcome any restriction
problems.
2. Engine Beds
These should be a minimum of 10mm thick, extended rearward and be welded to the
hull and forward to the bulkhead. Webs or gussets must be welded in place midway to
prevent flexing. They may be steel or stainless steel glassed into a GRP hull.
3. Pressurised Water Header Tank
The pressurised header tank should be mounted higher than the level of the engine
and no more than 1 metre from the engine, to prevent cooling system air locks.
4. Shaft Connection and Propeller Selection
Some type of flexible coupling must be used to connect the gearbox output flange to
the propeller shaft flange. Various coupling flanges are widely available to assist with
this.
Please note, underperforming engines will not be covered under warranty if the cause
of the poor performance is found to be the use of an inappropriate propeller.
5. Engine Anti-Vibration Mounts
Ensure that the engine feet do not end up at the top of the thread on the engine
mounts, this puts undue pressure on them and can result in excessive engine
movement and premature mount failure. If this is a problem put steel packing plates
under the mounts. Packing plates 25mm thick are available: order RDG3906 Engine
mount spacer. Alternatively they can be manufactured locally.
Ensure that the engine has been installed for at least 24 hours before shaft alignment
is checked, to allow the mounts time to settle under the engine weight.
