Error Detection Cooling System

1

Ask for the following information:

-

How old is the device (engine number and model)?

-

How many operating hours (wear and corrosion)?

-

How long does the problem already exist (gradual or sudden occurence)?

-

Operating conditions prior to occurence of problem (interior waters, salt water, muddy
or sandy water?)

-

What repair- or service works have already been carried out (exchange of impeller, etc.)?

-

At what engine speed does the problem occur?

-

At what engine load does the problem occur?

2

Raw water circuit (external)

2.1

At first, take into consideration the following possibilities:

-

Defective or faulty cooling water temperature sensor (high-riser)

-

Sufficient rate of flow for raw water
-

raw water pick-up damaged or clogged

-

wrongly mounted raw water pick-up

-

raw water filter clogged

-

stop valve (bottom valve) defective (only opens partially)

-

Raw water pump
-

impeller defective (broken or strong wear)

-

suction pipe from raw water filter to raw water pump clogged or deformed

-

shaft bearing defective

- Sealing

- O-ring of impeller housing defective
- impeller plate seal

-

Tandem cooler contaminated (e.g. through a part of broken impeller)

-

Tube stake - intercooler contaminatd

-

Heat exchanger exhaust
-

contaminated

-

seal in heat exchanger cover defective.

-

Ventilation

-

Alga vegetation on quill

-

Deformations on hull, etc.

2.2

- Problems of raw water supply due to troubles in the drive unit

- defective seals or water pipes in lower gear box
- damaged rubber seal on water pipe
- damaged seal on box inlet
- leaky impeller plate seal
- leaky O-ring on impeller housing
- defective hose connection between pivot housing and Cardan housing
- observe notes and instructions of manufacturer.

2.3

- Inspection wether air reaches raw water.

Procedure: Replace water hose between raw water pump and tandem cooler (fuel/hydraulic

cooler) by transparent plastic hose. Let the device run in a test tank or with the boat
in water, at rotation speeds which cause an overheating, in order to detect a possible
bubble formation in the transparent plastic hose.
