18:05 FUELING: Following safety precautions before, during and after fueling is
critical. Being familiar with all procedures and adhering to them each time you take on
fuel will help insure your safety. Avoid fueling at night or during a storm.
1. Close all hatches and ports.
2. Allow no smoking aboard, on or near the fuel docks.
3. Check fuel level.
4. Turn off any equipment which may generate heat or spark such as engine, stove,
heaters, radios, lights, etc. Turn off all electrical switches. Main switch and battery
switch are turned off after engine is stopped.
5. Anyone not involved with fueling should leave the boat.
6. Remove deck plate and position fill nozzle to remain in contact with metal deck
plate to prevent the generation of static electricity charges.
7. Have fire extinguisher(s) readily available.
8. Be aware of how much fuel is being taken on and double check that the appropriate
fuel is being delivered.
9. Slowly fill to no more than 95% full to allow for thermal expansion of fuel.
10. Replace deck plate cover securely and carefully clean up any spillage. Discard any
oily rags.
11. Check fuel tank vent at stern for overflow.
12. Check below decks and in bilge for fumes or fuel.
13. Open all ports and hatches for ventilation. Air out any fumes present.
19:00 ENGINE COOLING AND EXHAUST SYSTEMS
Heat expelled from combustion and that was developed by friction is absorbed by water
circulating in a water jacket throughout the engine. A variety of cooling systems have
been utilized by different engine manufacturers. Refer to your engine's owner's manual
for the type of system on your boat. The following is a brief description of the two most
common systems. (Refer to I­18 and I­19)
19:01 SEA WATER COOLING: Sea water is drawn through a strainer at the seacock thru
hull and into a water filter by an auxiliary water pump. This water then circulates
through the engine block and in some cases, through the reverse gear. It is then
discharged into the exhaust system. The water mixes with the exhaust gases in the
waterlock canister and is expelled through the exhaust port at the transom.
The waterlock canister provides a method to lift and push the exhaust gases and water to
the transom port. It also acts as a silencer to help quiet the inherent engine noise
related to the exhaust system.
The engine's sea water intake seacock must be open at all times when the engine is running
and closed when the engine is not used for extended periods.
19:02 FRESHWATER COOLING: Freshwater cooling provides a system which minimizes the
exposure of engine components to sea water. With this system, the raw water being drawn
into the boat is diverted at the engine and used to cool a separate closed freshwater
system by means of a heat exchange. A 50:50 mix of ethylene glycol anti­freeze and fresh
water is used in the freshwater portion of this system
The heat exchanger works in much the same way as a radiator in an automobile, except that
sea water rather than air is used to cool the engine's cooling water.
