Air ghtness is obtained partly by means of the plunger
one-way check valve that is set in the base of the valve
insert; complete air ghtness is ensured by the properly
fied valve cap. Before

Under certain condions aluminum boats are subject to
corrosion. There are different kinds of corrosion to happen,
among others: galvanic, stray current and poulce. All these types
of corrosion result in metal eaten away and if not stopped can
cause severe damage to your boat. Although these types of
corrosion can occur in fresh water; salt, brackish, polluted and
high mineral content water will greatly accelerate corrosion.
There are various variables which foster corrosion as salinity of
the water, temperature, organic material in the water, electrical
acvity nearby, presence of other metal, among others.
Corrosion is a common occurrence, but the deterioraon process
is usually slow with ample but subtle me to take correcve
acons. Boaters should protect the boat against corrosion in the
best feasible manner and be disciplined in looking for it.

Always watch for corrosion near bolt holes, chipped paint, behind
peeling paint and any place the aluminum has been scratched or
dented. Edges, cracks places that trap salt water and debris are
more suscepble for corrosion. Avoid build-up of organic
material, plant growth, algae or barnacles.
For corrosion in general, roune cleaning and maintenance is the
best hand you can give to your boat, specially in areas of difficult
access such as the space between the tube and the hull, where
different types of residues or organic material can cumulate and
create an environment for corrosion.
Poulce corrosion may occur when bare aluminum surfaces are
covered by absorbent materials, dirt and debris trapping
moisture against the unprotected metal surface. A way to prevent
the poulce corrosion is to repair scratches and dents as soon as
they occur, also to coat all bare metal surfaces, but the most
important, coated or not, you must keep the aluminum clean and
dry.
Addionally, boats used in afore-said water should be properly
protected with anfouling paint or a similar protectant, but it is
best to remove the boat from the water when not in use. It is
important to consider that anfouling products must be suitable
for aluminum. It must not be based on a dissimilar metal, copper
is parcularly problemac.
In some cases, it is also advisable to add extra zinc anodes
securely aached with clean and ght connecons. Never paint
or coat zinc anodes and replace if they are eroded to 50% or more.
Isolate the hull from electrical current. Make sure your baery is
grounded to your engine and do not ground electrical devices to
the aluminum hull.
Except for sacrificial anodes, do not place any metal to the hull
other than aluminum or high quality stainless steel. If you use
fasteners they should be plasc or stainless, not zinc, brass, copper
or iron based. Inside the boat, do not let any metal sit in the same
spot in the bilge for long me.
