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
gases pass through a water canister which can charge the exhaust manifold
with water vapour. This 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 sensors 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.
