Jet intake checks
Carefully check the jet intake under the boat
for weeds, debris, or anything else that might
restrict the intake of water. If the intake is
clogged, cavitation could occur, reducing jet
thrust, and possibly damaging jet pump parts.

In some cases, the engine may overheat be-
cause of a lack of cooling water, and damage
could result. If the jet intake is clogged, clean
it. (See page 120 for information on the jet in-
take.)
WARNING! Rotating parts could
cause severe injury or death. Before at-
tempting to remove weeds or debris from
the jet intake or impeller areas; shut off the
engine, remove the main switch key, and
then remove the engine shut-off cord (lan-
yard) from the engine shut-off switch.
Fuel system checks
Check the fuel filler hoses and joints in the en-
gine compartment for damage, looseness,
and signs of leaking. At least annually, or if a
problem is suspected, check the fuel tank and
fuel filler hoses and clamps. Have a Yamaha
Boat Dealer check the fuel tank and fuel filler
hoses and clamps.
Engine oil level check
Make sure that the engine oil level is between
the minimum level mark and maximum level
mark on the dipstick. (See page 75 for infor-
mation on checking the engine oil level.)
