Chapter 14:

SEASONAL MAINTENANCE

14.1 Storage and Lay-up

Before Hauling:

• Pump out the head. Flush the holding tank using clean soap, water and a deodorizer. Pump

out the cleaning solution.

• The fuel tank should be left nearly full to reduce condensation that can accumulate in the fuel

tank. Allow enough room in the tank for the fuel to expand without leaking out the vents.

Moisture from condensation in the fuel tank can reach such concentrations that it becomes

heavy enough to settle out of the gasoline to the bottom of the tank. Since fuel pickup tubes

are located near the bottom of the tank, this accumulated moisture can cause the engine to

run poorly or not at all after extended storage.

Chemical changes also occur as the gasoline ages that can cause deposits and varnish in the

fuel system as well as reduce the octane rating of the fuel. Severely degraded fuel can damage

the engine and boat fuel tank and lines.

Therefore, if your boat is not being run enough to require at least one full tank of fresh fuel

a month or during winter storage, a fuel stabilizer should be added to the gasoline to help

protect the fuel system from these problems. Operate the boat for at least 15 minutes after

adding the stabilizer to allow the treated fuel to reach the engine.

Your dealer or the engine manufacturer can provide additional information on fuel degradation

and fuel stabilizers recommended for your engine. For more recommendations for your

specific area, check with your local Pursuit dealer.

• Drain water from the freshwater system.

• Consult the engine owner’s manual for detailed information on preparing the engines for

storage.
