SEASONAL MAINTENANCE
13.1 Storage & Lay-up
Before Hauling
• Empty or pump out the portable head holding
tank. Flush the holding tank using clean water,
soap and a deodorizer.
• The fuel tank should be left nearly full to
reduce condensation that can accumulate in
the tank. Allow enough room in the tank for
the fuel to expand without leaking out the
vent. Moisture from condensation in the
fuel tank can reach such concentrations that
it becomes heavy enough to settle out of the
fuel to the bottom of the tank. Since fuel
pickup tubes are located near the bottom of
the tank, this accumulated moisture can cause
the engines 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. Yamaha
recommends using Yamaha Fuel Conditioner
and Stabilizer for their engines.
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
Crevalle dealer.
• Drain water from the fresh water system.
• Consult the engine owner’s manual for detailed
information on preparing the engine for
storage.
Lifting
It is essential that care be used when lifting your
boat. Make sure the spreader bar at each sling is
at least as long as the distance across the widest
point of the boat that the sling will surround. Once
the slings are in position, the fore and aft slings
should be tied together to prevent the slings from
sliding on the hull.
CAUTION
BOATS CAN BE DAMAGED FROM IMPROPER LIFTING AND
TRANSPORTING WITH FORK LIFTS. CARE AND CAUTION
MUST BE EXERCISED WHEN TRANSPORTING A BOAT WITH A
FORK LIFT. NEVER HOIST THE BOAT WITH A SUBSTANTIAL
AMOUNT OF WATER IN THE BILGE.
SEVERE GEL COAT CRACKING OR MORE SERIOUS HULL
DAMAGE CAN OCCUR DURING HAULING AND LAUNCHING
IF PRESSURE IS CREATED ON THE GUNWALES (SHEER) BY
THE SLINGS. FLAT, WIDE BELTING SLINGS AND SPREADERS
LONG ENOUGH TO KEEP PRESSURE FROM THE GUNWALES
ARE ESSENTIAL. DO NOT ALLOW ANYONE TO HAUL YOUR
BOAT WHEN THE SPREADERS ON THE LIFT ARE NOT WIDE
ENOUGH TO TAKE THE PRESSURE OFF THE GUNWALES.
Supporting The Boat For Storage
A trailer, elevating lift, well-made cradle or proper
blocking is the best support for your boat during
storage.
When storing the boat on a trailer for a long
period:
• Make sure the trailer is large enough to
properly support your boat and that it is rated
to support the weight.
• Make sure the trailer is on a level surface and
the bow is high enough so that water will drain
from the bilge and cockpit.
• Make sure the engine is in the down position.
• The trailer must properly support the hull. The
bunks and rollers should match the bottom of
the hull and should not be putting pressure on
the lifting strakes.
• Make sure the hitch is properly supported.
• Check the tires once each season. Add enough
air for the correct amount of inflation for the
tires as necessary.
