the flat seals (rubber) at the upper and lower ends of
the insert.
4. Wash the insert in white spirit, flush out internally and
blow dry using compressed air. Clean the housing.
5. Refit the parts in reverse order. Note that the lower flat
seal is equipped with cut outs for the flow of oil. Use
new sealing rings. Grease the cooler element pipe
connections with water-resistant grease before
connecting the coolant pipes.
6. Fill the engine with the coolant.
Oil coolers for all reverse gears
1. Loosen both the ends of the oil cooler and remove the

compressed air. Clean the end sides of the insert with
a wire brush and clean the inside of the tubes with a
suitable brush. Clean the housing.

screws too hard. Normally there should be a space
between the housing and the end covers.

The impeller should be changed once a year before the
beginning of the season.
Close the bottom valve and drain the seawater from the
engine.
1. Remove the pump end cover. Prize out the impeller
with the help of two screwdrivers.
NOTE. Place some kind of protection under the
screwdrivers in order not to damage the housing.
2. Clean the inside of the housing.
3. Press in the new impeller and fit the sealing washers
on the outer end of the impeller centre, if this has not
already been done. Fit the cover together with a new
gasket. Close the cocks and open the bottom valve.
Make sure that there is always a spare impeller and
gasket on board.
