It contains important information about warranty cards, service and maintenance which you, the owner, must be aware of, check and carry out.
Identification number Your engine and transmission has identification plates with identification numbers. This information should always be quoted when ordering service and replacement parts. There are probably similar plates on your boat and its equipment. Make a note of the details below, make a copy of the page and keep it so that you have a copy should the boat be stolen.
Orientation The orientation illustrations do not illustrate all combinations of engines and reverse gears respectively drives It is therefore possible that information about your reverse gear or drive is with another engine model than the ones covered here. 1. Coolant filler cap 2.
Instrumentation This chapter only describes the instrument panels available from Volvo Penta as standard alternatives for your engine. Note that in certain boats instruments, alarm panels, key switches etc. may be installed separately without the instrument panels shown here. If you want to install additional instrumentation, or your boat is equipped with instruments not described here, please contact your Volvo Penta dealer.
Warning display If the acoustic alarm sounds, one of the three warning lamps (10-12) on the instrument panel starts to flash to indicate the source of the alarm. 11 12 10. Engine coolant temperature too high. 11. Low oil pressure. 12.
Controls This chapter only describes the controls available from Volvo Penta as standard alternatives for your engine. If your boat is equipped with controls which are not described here and you feel uncertain about the functions, contact your Volvo Penta dealership.
Power Trim The SX propulsion system is equipped with a Power Trim hydraulic trim system which makes it possible to adjust the angle of the drive in relation to the stern of the boat. This adjusts the boat’s trim to obtain maximum comfort and fuel economy in different operating conditions.
Starting the engine Make a habit of checking the engine and engine compartment visually before starting the engine. This will help you to quickly detect anything unusual that has or is about to happen. Also check that instruments and the warning display are indicating normal values when you have started the engine.
4. Turn the key to position ”III” to start. Release the key as soon as the engine has started, the key will automatically spring back to the ”I” position. If the engine did not start the key must first be turned to the ”0”...
Fault-tracing. If the engine speed exceeds wide open throttle range a propeller with a higher pitch should be selected. Ask your Volvo Penta service dealer for advice. Maneuvering All shifting between ahead and astern must be done at engine idle speed.
Trolling operation valve HS25 reverse gear can be equipped with a trolling operation valve which makes it possible to steplessly reduce the boats lowest speed by 1-80% at engine speeds up to 1200 rpm. IMPORTANT! At higher speed the reverse gear may overheat. When sailing When sailing the control lever should be in the neutral position if the boat is equipped with HS25 reverse gear.
Power Trim while running The SX propulsion system is equipped with a Power Trim hydraulic trim system which makes it possible to adjust the angle of (trim) the drive in relation to the stern of the boat. This adjusts the boat’s trim to obtain maximum comfort and fuel economy in different load, speed, wind and sea conditions.
Page 23
At planing speed Trim the drive out to the operating position which provides the most stable and comfortable running. If the boat has twin motors the drives can be trimmed with different angles to compensate for side winds and to a certain extent compensate for uneven loading on one side of the boat or the other.
Volvo Penta workshop. If only the propeller has been damaged it must be replaced. Launch the boat and test drive. If there are still vibrations it must be inspected by an authorized Volvo Penta workshop. IMPORTANT! To prevent galvanic corrosion any damage to the paintwork on the drive and propeller must be repaired before launching the boat: See section “Laying up/Launching”.
Stopping the engine The engine should be run for a few minutes at idle (in neutral) before turning it off. This will avoid boiling and even out the temperature. This is especially important if the engine has been operated at high engine speeds and loads. Stopping Turn the key to stop position ”S”.
Cold weather precautions To prevent freezing damage, the seawater system must be drained and the freshwater system coolant must have sufficient antifreeze protection. See chapter Maintenance ”Cooling systems”. IMPORTANT! A poorly charged battery may burst as a result of freezing. Laying up If the boat is not going to be used for some time but is being left in the water, the engine must be run to operating temperature at least once...
Maintenance schedule Your Volvo Penta engine and its equipment is designed for maximum service life and reliability. They are built to survive in a tough marine environment, but also to cause as little environmental impact as possible. Regular maintenance according to the following schedule is necessary if the engine and transmission are to operate without problems.

Drive belts. General WARNING! Always turn the engine off before starting maintenance work. Check the tension and condition of the belts regularly. A belt that is too tight can damage the bearings and a belt that is too loose can result in slippage. Check and adjust as necessary after operating the engine when the belts are warm.
Lubrication system IMPORTANT! With a new or reconditioned engine, the oil and oil filters must be changed after 20-50 hours of operation. After that they should be changed every 200 operating hours or at least once a year. Use only the recommended grades of oil: see the chapter ”Technical Data”. Oil level.
In event of frost risk Use a mixture of Volvo Penta antifreeze and pure water (the mixing ratio is on the packaging). Mix the coolant in a separate container before filling.
Page 33
No risk of freezing When there is never a risk of freezing water may be used as coolant with addition of Volvo Penta anti corrosion agent. Mix according to the instructions on the packaging. Warm up the engine after filling to allow the additive to work as efficiently as possible.
Page 34
Coolant. Replacing/Draining The antifreeze additive rust-proofing properties diminish with time. It is therefore important that the coolant is replaced according to the service schedule below. To avoid reduced cooling performance caused by scaling in the coolant system it should be flushed when it has been drained.
Page 35
Seawater system. Draining To prevent freezing damage the seawater system must be drained in cold weather where there is a risk of frost. IMPORTANT! If the boat does not have a seacock (boats with SX for example) the boat must be standing on dry land in order to drain the entire seawater system.
