Introduction
The Perkins M92B marine engine is the latest development from Perkins Engines Company Limited together
with Wimborne Marine Power Centre. The engine is designed specically for use in commercial and pleasure
boat applications.
Over sixty years of diesel production experience, together with the latest technology, have been applied to the
manufacture of your engine to give you reliable and economic power.
Danger is indicated in the text by two methods:
Warning! This indicates that there is a possible danger to the person.
Caution: This indicates that there is a possible danger to the engine.
Note: Is used where the information is important, but there is not a danger.
General information

How to care for your engine
Warning! Read the “Safety precautions” and remember them. They are given for your protection and must be
applied at all times.
Caution: Do not clean an engine while it runs. If cold cleaning uids are applied to a hot engine, certain
components on the engine may be damaged.
This handbook has been written to assist you to maintain and operate your engine correctly.
To obtain the best performance and the longest life from your engine, you must ensure that the maintenance
operations are done at the intervals indicated in “Preventative maintenance”. If the engine works in a very
dusty environment or other adverse conditions, certain maintenance intervals will have to be reduced. Renew
the lter canister and lubricating oil regularly in order to ensure that the inside of your engine remains clean.
Ensure that all adjustments and repairs are done by personnel who have had the correct training. Perkins
distributors have this type of personnel available. You can also obtain parts and service from your Perkins
distributor. If you do not know the address of your nearest distributor, enquire at www.perkins.com/Marine.
The “left side” and “right side” of the engine apply when the engine is seen from the reverse gearbox end.

General safety precautions
These safety precautions are important.You must refer also to the local regulations in the country of use.
Some items only apply to specic applications.
• Only use these engines in the type of application for which they have been designed.
• Do not change the specication of the engine.
• Do not smoke when you put fuel into the tank.
• Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a
safe place.
• Do not put fuel into the tank while the engine runs (unless it is absolutely necessary).
• Do not clean, add lubricating oil, or adjust the engine while it runs (unless you have had the correct
training; even then extreme care must be used to prevent injury).
• Do not make adjustments that you do not understand.
• Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.
• Other persons must be kept at a safe distance while the engine, auxiliary equipment or boat is in
operation.
• Do not permit loose clothing or long hair near moving parts. Warning: Some moving parts cannot be
seen clearly while the engine runs.
• Keep away from moving parts during engine operation.
• Do not operate the engine if a safety guard has been removed.
• Do not remove the ller cap or any component of the cooling system while the engine is hot and while
the coolant is under pressure, because dangerous hot coolant can be discharged.
• Do not use salt water or any other coolant which can cause corrosion in the closed circuit of the cooling
system.
• Disconnect the battery terminals before a repair is made to the electrical system.
• Only one person must control the engine.
• Ensure that the engine is operated only from the control panel or from the operators position.
• If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.
• Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.
Protect your hands with gloves or a special solution to protect the skin.
• Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated
with oil into the pockets of clothing.
• Discard used lubricating oil in accordance with local regulations to prevent contamination.
• Ensure that the control lever of the transmission drive is in the “out-of-drive” position before the engine is
started.
• Use extreme care if emergency repairs must be made at sea or in adverse conditions.
• The combustible material of some components of the engine (for example certain seals) can become
extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or
with the eyes.
• Always close the seacock before the removal of any component of the raw water circuit.
• Always use a safety cage to protect the operator when a component is to be pressure tested in a
container of water. Fit safety wires to secure the plugs which seal the hose connections of a component
which is to be pressure tested.
• Do not allow compressed air to contact your skin. If compressed air enters your skin, obtain medical help
immediately.
• Turbochargers operate at high speed and at high temperature. Keep ngers, tools and debris away from
inlet and outlet ports of the turbocharger and prevent contact with hot surfaces.
• Do not clean an engine while it runs. If cold cleaning uids are applied to a hot engine, certain
components on the engine may be damaged.
• Fit only genuine Perkins parts.

Engine guarantee
If a claim under guarantee is necessary, the boat owner should make a guarantee claim on the nearest Perkins
marine distributor or an approved dealer.

The engine identication number is shown at two locations on the engine: stamped on a plate at the right side
of the cylinder block (C1) and shown on a label (D1) tted to the front of the timing case.
An example of an engine number is: RE51267U123456L.
The components of the engine number are as follows:
RE51267U123456L
RE Type code letters
51267 Build list number
U Built in the UK
123456 Engine serial number
