Benefits of Propshield
Why use Propshield?
There are many benefits when using Propshield Antifouling Grease on your
stern gear and this page will help you find out what they are and how
they can benefit you and your vessel.
Firstly you need to find out if
Propshield is right for you and your vessel.
To find out ask yourself the following questions:
Does my boat spend most of its time on its mooring
making a home for barnacles?
Do my props and stern gear get coated in
these creatures?
Are my propellers green at the end of the
season through electrolysis?
Do I lose speed after only a few weeks after
re launch?
Is stern gear fouling costing me a fortune in
wasted fuel and reduced speed?
Do I
spend a fortune buying and refurbishing new propellers?
If the answer to any of these
questions is yes...
then
Propshield is definitely the solution for you!
List of Benefits
Use on propellers, prop shafts, rudders P & A brackets, outdrives,
outboards, inboards etc
Propshield is a very versatile product and can be used on virtually any
type of stern gear and on any metal material (doesn't perform on
plastics). It can also be used on painted surfaces so outdrive legs can
be protected. Propshield is an all round stern gear antifouling work
horse.

Eradicates / reduces
barnacle attraction
During our research we have been amazed at the effects of minimising the
growth of barnacles. In many cases the barnacles are completely
eradicated and even in the most foul of waters only a few barnacles are
able to attach themselves to your stern gear. Propshield ensures hard
growth cannot get a permanent grip on the surface, when the vessel is
moving the force of the water dislodges any growth that has managed to
adhere itself to the propeller etc.

Stops / reduces
the effects of electrolysis
Propshield forms a barrier between the stern gear and the water so
insulates the metal or painted surface. If you have suffered from
electrolysis (green deposits on bronze blades) then you will notice that
this either completely disappears or is minimised in extreme cases.

Saves fuel due to cleaner
stern gear
You will save a significant amount of fuel if your props are clean. If
you suffer from black smoke at full throttle then the chances are that
you have barnacle build up on your props. Alternatively you may find
that the props need slightly repitching to a finer pitch. Boat yards
will always tell you that black smoke is always caused by faulty
injectors or pumps on diesel boats. This is not always the case, check
your props first.

Maintains speed of vessel
Using Propshield maintains the speed of your vessel as the hydrodynamics
of the propeller blades are maintained. Any fouling on your props means
you will loose speed which is particularly important on planning boats.

Reduces prop repair costs
How can Propshield reduce your repair costs? Well if they do not oxidise
and dont suffer from electrolysis then this should reduce the need for
them to be re fettled quite so often. In the case of electrolysis it
could mean the difference between replacing the prop or not. If you prop
is green (bronze only) at the end of the season then the copper is
leaching out of the bronze and weakening the blade.

Propellers last years longer
As we have mentioned above the effects of the marine environment are
very harsh and your props are finely engineered pieces of equipment
which cost hundreds of pounds in most cases. If they are not maintained
they will eventually fail in service. Propshield will significantly
extend the life of your props by providing a barrier to that harsh
environment.

Stops corrosion on outdrive legs (can be applied over paint)
Corrosion on outdrive legs can be devastating and can ruin aluminium
castings in a few months so an application of Propshield will prevent
this damage.

Economical to use
Our research shows that one pot of Propshield will cover the propshafts
and propellers of a 12 metre boat for two applications. That is a primer
coat and second coat, twice.

No wastage
There is no wastage with this product. If you have some left over simply
return it to the pot in a melted liquid form and use it again when you
are ready. If has been diluted with white spirit simply let the carrier
evaporate and re dilute it for use when you next need it.

Vessels can
be used immediately after application
After application you do not need to let the product harden as it will
be solid enough as soon as the heat is removed from the metal.
Method two is slightly different in that the carrier needs to evaporate
but this takes only a few minuets and it will take considerably longer
than that to launch your boat. By the time it hits the water it will be
hard. If for some reason you have over diluted the product then you
should wait until the surface has dried to a sticky film. You may even
need to apply more coats if it has been diluted too much.
Back to Top
Will not dissolve in water
Propshield will not dissolve in water.
However it will gradually wear off but it takes a considerable amount of
use before it becomes ineffective.
Back to Top
Penetrates
metal up to a tenth of a millimetre
Propshield penetrates the surface of the metal so forming an invisible
barrier which remains active and deters barnacle attraction. This
penetration also works with painted surfaces.
Back to Top
Easy to apply
Propshield is easier to apply when the temperature is above 15 degrees
centigrade, if below this temperature just drop the pot of Propshield
into hot/boiling water until the grease is malleable. Above 15 degrees
it gets even easier as the metal holds the heat more readily. Method B
is better at low temperatures as the first coat is diluted with white
spirit and therefore not temperature dependant. However the second coat
is sensitive to the ambient temperature.
Back to Top
Stops oxidation of all metals
Propshield will stop the oxidation of all metals by providing a durable
barrier between the metal surface and the environment.
Back to Top
Compatible with stainless steel, bronze, aluminium etc
As mentioned before you can use this product on any metal but do not use
on synthetic materials such as plastics.

Environmentally friendly
This is a green product that will not cause any harm to the environment.
It will not hurt aquatic marine life forms (even barnacles, they just
cant stick to it). It is biodegradable over extended periods so will
not pollute rivers or the sea. The additives in Propshield are as eco
friendly as we were able to find and are used in other industries where
pollution is forbidden. We are confident that this is safe to use both
in the production process for the end user and the environment.

Made from
renewable resources (NOT OIL BASED)
The base product is produced from the grease which naturally occurs in
sheep wool and is a by-product of the wool production process. The sheep
are not harmed in any way and when it is hot this is a positive benefit
to them.
The packaging we use is also recyclable and so are the drums that the
raw materials are packed in when they are delivered to Prop Protector. We
have gone to extreme lengths to ensure that this product is as natural
as possible whilst maintaining its effectiveness in the marine
environment.
