From Stuart McNamara Lough Ree Powerboat School www.powerboat.org in
Ireland .
We were shocked recently with what we encountered with two "spurious" or
or "non Yamaha" Yamaha out board engine
Kill cords .
During the the last few weeks , while stopping off by boat at two seperate
marinas around Ireland , I called into the shops for a chat and ( as you
do ) bought a couple of knick knacks or small items to be polite , including
on each
occasion a spare Yamaha Killcord which went into the kit boxes of two of my
School's Rigid Inflatable Boats which are fitted with Yamaha Out Board
Engines .
A few weeks later one of these cords failed where the cord doubles back and
secures on itself under a metal clip . It happened while the cord was being
pulled off the throttle control box at the end of the day by an Instructor .
Obviously the metal clip had pinched the kill cord and cut into the plastic
of the cord . We inspected all our other cords . They all appeared ok .
A few days later , the other cord was being stretched by one of my
Instructors prior to clipping it around her leg when it snapped right in the
middle . Again it would appear that the plastic of the cord had just failed
with out warning or discolouration / fraying of any kind .
Each of these cords had been used no more than three times .
Bobby Killen of Killen Marine in Dublin is widely recognised as the Out
Board Engine Guru here in Ireland and is also a Yamaha main dealer .
He tells me that the genuine Yamaha Kill cord has a tough string core which
means that the outer plastic covering is for protection rather than strenght
. The spurious ones are pure plastic with no central core so when they fail
, they really fail. It also explains why they are stiffer / not as flexible
to stretch .
As a result of this I have now banned spurious Kill cords from all of the
boats in our Powerboat School and would advise all other outboard engine /
PWC users to do the same .
