Post-Operation Checks - Yamaha AR210 2020 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° angle, you may not notice this, but at
a smaller angle, say 10°, it can be very strong.
Be prepared to steer and balance as neces-
sary.

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
recommended. Proper flushing of the cool-
ing system on each engine is not possible
with the boat in the water. In addition, condi-
tions such as stray electrical voltage in the
water, marine organisms, and saltwater cor-
rosion 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
the hull and jet pump areas. The frequency of
10˚
maintenance required will depend upon
whether the water is salt water or fresh water
and other local water conditions.
