4.2.1. Washing the Jet
Every time the boat is lifted out of the water, it is advisable to wash it with fresh
water . This clears possible salt accruals and impurities, which leads to the reduction of
corrosive effect due to conditions.
4.2.2 Lubricating the Bearings
4.2.2.1. Lubricating the Front Bearing
The lubrication of the front bearing is carried out from the engine compartment side.
To facilitate greasing, there is a hose with a grease nipple at one end connected to the
bearing housing. The end of the hose can be attached in the loose space so that using the
grease gun is easy.
Excess grease exits the bearing housing automatically. When lubricating, only add 4-5
injections of grease with the grease gun.
The lubrication interval for the bearing is 50 hours or twice a year at minimum.
4.2.2.2. Lubricating the Rear Bearing
It is easiest to carry out the lubrication of the rear
bearing when the boat is out of the water, but it
can also be done while the boat is in the water. The
lubrication is carried out through the steering nozzle
from the nipple in the middle of the stator (figure
4.2.2.2-1).
Excess grease exits the bearing housing
automatically. When lubricating, only add 2-3
injections of grease with the grease gun.
The lubrication interval for the bearing is 50 hours or
twice a year at minimum.
The rear end bearing supports the shaft and centers it
in respect of the duct. This is why excessive wearing
of the bearing affects the behaviour of the impeller.
When the bearing has been worn enough, excess
vibration builds up in the unit and “clinking” can
be heard from the impeller. In this case the impeller
wears also and its efficiency is reduced.
A worn bearing should be replaced with a new one
when the aforementioned symptoms appear.
