Operating In Shallow Water; Swimming And Skiing - Marine 10 M Owner's Manual

Once on plane, trim the engine up/out slightly to avoid a bow-down condition called
"plowing". Plowing can cause inefficient and unpredictable "bow steering" or "over
steering". In this condition, attempting to turn or encountering a moderate wave may
result in an abrupt turn or spinout.
Trimming the engine too far up/out can cause a bow-up condition leading to
"porpoising" (bouncing) or propeller ventilation. If you notice a sudden increase in
propeller speed, reduce engine RPM and trim the drive down/under/in until propeller
ventilation stops.
In most cases, vest performance is obtained with the unit positioned so that the boat
runs at a 3 to 5 degree angle to the water (front of hull just slightly out of the water)

OPERATING IN SHALLOW WATER

COLLISION
underwater/floating objects may be present. Hitting an object at high speed or severe
angle can cause serious injury and/or damage your boat.
Shallow water presents obvious hazards. In addition to insufficient draft, shallow
means sand bars, stumps, or other unmarked obstructions in deep water.
Other hazards in shallow water include mud, sand, weeds and debris, which can foul
your engine´s cooling water intakes.
Know the area I which you are operating. Consult charts and ask local boaters. If you
know or suspect shallow water, post a lookout and proceed slowly.
When beaching, be aware how tide can affect the boat. Never leave a beached boat
unattended or unanchored.

Swimming and skiing

SWIMMING/DIVING HAZARDS
Keep clear of areas designated only for swimmers and scuba divers. Recognize
markers used for such areas.
Never swim when there is lightning in the area.
SKIING HAZARDS
Skiers must use a safety-approved personal flotation device.
Ski only during daylight when the visibility is good.
Avoid shallow water, other boats, navigational aids and other obstructions.
Keep at least 30 meters (100 feet) from other objects.
Never drive directly behind a water skier.
A competent observer must watch the skier at all time. A competent observer is a
person who has the ability to assess when a skier is in trouble, knows and
understands standard skiing hand signals and is capable of helping a skier.
