COOLING WATER HOSES /
EXHAUST HOSES
12
As rubber becomes brittle with time, you should
occasionally check the hoses for any signs of cracks
or damage
Leaking cooling water hoses are a safety hazard
and can cause the engine to overheat or the boat
to become filled with water.
Leaking exhaust hoses can cause dangerous
exhaust fumes on board and allow water to get
into the boat.
Carefully inspect the hoses and clamps
of the cooling system and exhaust
system. Replace those hoses which do
not feel soft and pliable. Tighten all hose clamps.
Check the condition of the hoses and
that all hose clamps are securely
fastened.
