Post-Operation Checks - Yamaha AR190 2012 Owner's/Operator's Manual

Operation
To cross a wake or swell, change your speed
and choose the angle at which you cross the
wake or swell. Usually, a slower speed and
"quartering" the wake (crossing at an angle)
will reduce the jolt.
Two other things you may notice. The first is
that crossing a group of wakes or swells is not
as easy or smooth as crossing just one wake.
The second is that when you quarter the wake
or swell, the boat will try to steer away from
the wake or swell. When crossing at a 45° an-
gle, you may not notice this, but at a smaller
angle, say 10°, it can be very strong. Be pre-
pared to steer and balance as necessary.

These post-operation procedures are devel-
oped to help preserve the long-term appear-
ance and reliability of your boat. Perform
these procedures as soon as possible after
the boat is loaded back on the trailer after the
day's use.
Some owners prefer to moor their boat sea-
sonally, rather than keeping it on the trailer
between uses. Extended mooring is not rec-
ommended. Proper flushing of the cooling
system is not possible with the boat in the wa-
ter. In addition, conditions such as stray elec-
trical voltage in the water, marine organisms,
and saltwater corrosion can adversely affect
the life of many boat components. NOTICE:
Leaving the boat in the water for extended
periods will accelerate the rate of normal
deterioration of the jet pump components,
sacrificial anodes, hull finish and other
components.
If you do decide to moor your boat, be sure to
remove it from the water periodically to clean
10˚
the hull and jet pump area. The frequency of
maintenance required will depend upon
whether the water is salt water or fresh water
and other local water conditions.

10 to 15 seconds. NOTICE: Never run
the engine at full throttle or for more
than 15 seconds while the boat is out
of the water. The engine may overheat
and/or seize.
