5. Refuelling
•
All Shire boat engines run on diesel fuel.
•
Please note that when the vessel is to be left for any period of time, the fuel tank
should be left full to eliminate the build-up of condensation and formation of water in
the fuel tank.
•
Engine to be turned off while refuelling
•
The fuel type for all Shire boat engines is diesel.
DO NOT USE BIODIESEL.
6. Diesel Fuel Additive
The use of diesel fuel additive is strongly recommended on Shire engines. The quality of
the fuel available when cruising is often unknown. Also the fuel may have been in storage
for long periods of time. The use of additives will ensure that your engine fuel injection
system is in top condition which should result in many years of smooth reliable operation,
without the cost and inconvenience of expensive breakdowns due to poor quality fuel. It
has also been found that improvements in fuel consumption and start ability are an added
benefit of using this product. Diesel fuel additive is available from your Shire dealer in a
handy 375ml container, Part Number RDG80210219.
7. Exhaust Hose Sizes (River Boat)
•
Use 50mm ID marine flexible exhaust hose on the Shire 30, 40 and 50 engines.
60mm is an option on the Shire 40 and 50 engines. Do not step down to a smaller
size.
•
When a PRM 260 gearbox is fitted, a 60mm ID hose is standard.
8. Exhaust Back Pressure (Work Boat with dry exhaust)
•
The engine exhaust outlet must be at least 300mm (12”) above the outside seawater
level of the hull. If not an exhaust high rise kit and/or lock box/swan neck must be
used to prevent sea water flowing back up the exhaust and causing engine damage.
The back pressure falls within the manufacturers recommended range when using the
optional exhaust system (see “
19. Exhaust System” from “Section 3 – Installation”
) with the
engine.
