and/or blocks should match deadrise angle and provide
adequate support and stability.
* When lifting the boat, keep the bow higher than the
stern so the exhaust lines can drain. This will keep water
from running forward through the manifold and into the
engine itself where the water can become trapped.
Note: Keep the bow higher than the stern every time the boat
is lifted. Do not lift the stern to change a propeller. Doing so
can cause water to enter the engine. Engine failure is possible
if water enters the engine cylinders. This water can cause
hydrolock and bend the piston rods. Even a small amount of
water can cause rust or other damage.
14.6.3 Draining Your Boat
Your boat has bilge pumps for draining water from the
bilges. Some compartments in the bilge may not drain
completely because of the position of the boat. Pump
these compartments out then use a sponge to remove all
remaining water.
Procedures for draining and winterizing the fresh water
system are in this section under the “Preparing for
Storage” heading.
14.6.2 Preparing for Storage
* Clean, scrub, and sponge the hull and deck as soon as
the boat is pulled from the water and is still in the sling.
Cleaning marine growth from the hull is easier when it is
still wet.
* Clean the inside of all hull openings, through hull fit-
tings, and screens. Inspect the hull and underwater gear
for signs of wear, deterioration, or damage. Note any
damage to the propulsion equipment, helm area, cabin,
etc. Make repairs, if at all possible, before covering your
boat.
* Fill the fuel tanks with treated fuel to prevent conden-
sation. If you use a stabilizer or conditioner, be sure to
follow the instructions on the container.
Important: Do not overfill fuel tanks so fuel flows from the vent.
Allow room in the tanks for fuel to expand.
** Prepare the Engines for Storage:
* In areas where temperatures fall below freezing, the
bilge area under the engines must be pumped out and
sponged completely dry. Check for areas that do not
drain to the pumps. Drain mufflers.
Note: Refer to the engine owner’s manual for winterization and
storage procedures.
** Prepare the Batteries for Storage:
* Be sure main battery breakers are off.
* Remove batteries from boat and store in area where
temperatures remain above freezing.
* Place batteries on a wooden pallet or bench.
* Keep batteries charged. Check electrolyte levels regu-
larly. Add electrolyte if needed.
** Prepare Holding Tank
* Empty and rinse holding tank until tank is clean.
* Close head intake seacock and remove hose.
* Pour the nontoxic antifreeze into the head and keep
flushing the head until the antifreeze reaches the holding
tank.
* If your boat has a macerator discharge and the boat
is removed from the water, run the macerator pump long
enough for antifreeze to run through the pump and the
lines.
* Remove drain plug from seacock while valve is closed.
Allow line to drain. Replace drain plug.
** Prepare the Fresh Water System:
* Remove the fresh water supply by opening the hot and
cold faucets in the galley for 10 minute intervals. Repeat
until the fresh water tank is empty.
* Open all faucets: galley, shower, cockpit shower, etc.
* Drain the water heater. Disconnect lines from the
engine heat exchanger (if equipped). Drain exchanger
and lines.
* Remove hot and cold water lines and hook them
together.
* Remove inlet hose from tank and insert it into a con-
tainer of nontoxic antifreeze. Turn pump on. Starting
at faucet furthest from pump, open all faucets until anti-
freeze flows out.
