Operation; Pre-Starting Check List; Operating In Freezing Temperatures; Operating In Salt Water Or Polluted Water - Mercury 200 OptiMax DTS Manual

Pre-Starting Check List

• Operator knows safe navigation, boating, and operating procedures.
• An approved personal flotation device of suitable size for each person aboard and readily
accessible (it is the law).
• A ring type life buoy or buoyant cushion designed to be thrown to a person in the water.
• Know the boats maximum load capacity. Look at the boat capacity plate.
• Fuel supply OK.
• Oil supply (oil injection) OK.
• Arrange passengers and load in the boat so the weight is distributed evenly and everyone is
seated in a proper seat.
• Tell someone where you are going and when you expect to return.
• It is illegal to operate a boat while under the influence of alcohol or drugs.
• Know the waters and area you will be boating; tides, currents, sand bars, rocks, and other hazards.
• Make inspection checks listed in Maintenance - Inspection and Maintenance Schedule.

Operating In Freezing Temperatures

When using your outboard or having your outboard moored in freezing or near freezing temperatures,
keep the outboard tilted down at all times so the gearcase is submerged. This prevents trapped water
in gearcase from freezing and causing possible damage to the water pump and other components.
If there is a chance of ice forming on the water, the outboard should be removed and drained completely
of water. If ice should form at the water level inside the outboard driveshaft housing, it will block water
flow to the engine causing possible damage.

Operating In Salt Water Or Polluted Water

We recommend that you flush the internal water passages of your outboard with fresh water after each
use in salt or polluted water. This will prevent a buildup of deposits from clogging the water passages.
Refer to Maintenance - Flushing The Cooling System.
If you keep your boat moored in the water, always tilt the outboard so the gearcase is completely out of
water (except in freezing temperatures) when not in use.
Wash the outboard exterior and flush out the exhaust outlet of the propeller and gearcase with fresh
water after each use. Each month, spray Mercury Precision or Quicksilver Corrosion Guard on external
metal surfaces. Do not spray on corrosion control anodes as this will reduce the effectiveness of the
anodes.

Operating at High Elevations

Your engine automatically compensates for high elevation changes. A different pitch propeller may help
reduce some normal performance loss resulting from reduced oxygen in the air. Consult your dealer.
