The Vibra-Stop Bush Kit is the
ultimate in vibration reduction for outboard powered
boats. Once in operation the Vibra-Stop Bush Kit fully
insulates the outboard engine from the boat, it also forms a
flexible or elastomeric mount between the boat and the outboard
engine. This flexible or elastomeric mount is where the
vibration is dissipated rather than being transferred into the
boat.
Nylons (cutting board type
material) and/or wood are limited in terms of reducing vibration due
to the mount still being rigid or hard mounted.
With outboard engine and
stern-drive applications the biggest disadvantage is the outboard
must push the boat through the water, this in turn means the engine
mounts in the outboard engine are loaded and any vibration passing
through the mount is transferred into the boat.
With outboard drive units
there are three main components that directly attribute to increased
noise and vibration levels; the first is the power-head or engine of
the outboard motor; the second is the gearbox and
drive-shaft transmissions; and the third is the propeller. Any
one of these three can make a difference between a smooth and quiet
engine and a harsh engine.
By using the Vibra-Stop
Bush Kit a large percentage of vibration can be dissipated
before entering the boat. Aluminium is inherently a noisy
material due to the nature of the aluminium material being so hard
that a small amount of vibration in the boat will amplify throughout
the boat.
Fibreglass boats will absorb
vibration and resonance a lot better than aluminium boats but there
are still significant gains to be made by using the Vibra-Stop Bush
Kit on Fibreglass boats.
Suits outboard motors up to 115hp
Bushes available in 25mm, 40mm, 50mm,& 70mm. |
