Lower fuel quality can cause interruptions in operation. Use only oil with quality CD (DS) according to the API-System. Volvo Penta oil for diesel engines can be used with advantage since it meets these quality demands. See under “Technical Data ” concerning viscosity if any other oil is used. A new marine engine must be run-in with due care during the first 20 hours of operation. If full output is taken out during this time, it should only be done for short periods. Oil change. Change the engine oil and oil filter after the engine has been run for 20 hours. See further under “Checks and Service “. Max. engine speed: MD7A 43.4 rev/sec (2600 rpm). In order to select the correct propeller, reference is made to the Volvo Penta propeller diagram. Check the engine speed with normal load in the boat. I n order to obtain maximum engine performance, an engine speed as high as possible should be chosen but not, however, greater than 43.4 rev/sec (2600 rpm). NOTE! When the boat has been in the water for some time, the speed and max. rev/mm can drop due to marine growth on the hull. Prevent marine growth by painting the bottom of the boat with antifouling paint. If the boat is equipped with S -drive model MD7A/110S ­ or any other S-drive model ­ it is important not to use an anti-fouling paint which contains copper. See further “Service in connection with launching “. RUNNING-IN ENGINE SPEED 3 GENERAL INFORMATION SAFETY EQUIPMENT Irrespective of whether the boat is being used for long cruises or short bathing trips, the boat should be equipped with the safety equipment listed below.
