Lambda Sensor Installation
PWC exhaust systems use a cooling water jacket to surround the exhaust
manifold and some of the exhaust muffler and associated tubing. The exhaust
gas
es pass through a water canister which can charge the exhaust manifold
with water vapour. T
his water vapour can drastically shorten the lifespan of
Lambda sensors, sometimes to less than one hour.
Important: We do not advise the fitting of lambda sensor
s unless you are
prepared to replace them frequently.
Yamaha Lambda Sensor
Suitable sensor mounting position is towards the rear of the
exhaust manifold.
Kawasaki Lambda Sensor
Suitable sensor mounting position is on the
inboard side of exhaust
casting on circular flat.
