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

Jet intake
In some cases, the engines may overheat be-
cause of a lack of cooling water, and damage
could result. If the jet intakes are clogged,
clean them. (See page 182 for information on
the jet intakes.)
WARNING! Rotating parts
could cause severe injury or death. Before
attempting to remove weeds or debris
from the jet intakes or impeller areas; shut
off the engines, remove the main switch
keys, and then remove the engine shut-off
cord (lanyard) 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 122, 123 for
information on checking the engine oil level.)
