General information:
About the workshop manual:

This Workshop Manual contains technical data, descriptions, and overhaul instructions for the standard versions of AQ150. Only the engine model designation are referenced exclusively throughout this Workshop Manual, without the drive/reverse gear. Where there are differences between engine units for the drive and reverse gear versions, the complete designation is stated, e.g. AQ150A.

• The engine designation and serial number shall always be given in correspondence to the Service and Parts Department. The Workshop Manual shows the work procedures carried out on a AQ150 engine equipped with freshwater cooling. The procedures are identical on other versions unless otherwise stated in text or illustrations. Please note that the illustrations used do not always fully correspond with the other engine version.
• The abbreviation FWC is used for freshwater cooled engine and SWC is used for sea water cooled engine. The product designation and number should be given in all correspondence about the product. This Workshop Manual has been developed primarily for Volvo Penta service workshops and qualified personnel.
