combustion.

An allowance must be made for any grills, louvres or bends placed in the
airflows and generally an increase of 25% in area is sufficient to overcome any
restriction problems.

hull and forward to the bulkhead. Webs or gussets must be welded in place midway
to prevent flexing.
3. Engine Cooling Water Inlet and Outlet Hose Connections
• The connections are on the right hand (starboard) side of the engine.
• Use 100mm ID suitable machine flexible exhaust hose. Do not step down to a smaller
size.

temperatures in excess of 100°C.
