Volvo Penta Marine bought out OMC Stern drive, many years ago, and the product below is a combination of pre and post merger product information. It is important to know what you have, when trying to service the product you're working on.

   Also, It is very important to note that some older AQ series Volvo stern drives were packaged with marine engines by companies other than Volvo Penta. When encountering an older marine engine that does not have Volvo's logo and serial number tag on the engine; there is a good chance that although it is a Volvo stern drive, the "engine" was not from Volvo Penta and, in some cases, parts are not currently available from them. As far as the stern drive itself goes; parts are available for most of the out-drives they ever built.

   Stern drive facts:

* All Volvo stern drives require a left hand rotation engine. (rotation viewed from the flywheel end.)

* AQ series SP 270/280/290 Volvo stern drives can turn right or left hand rotation propellers.

*SX SP Volvo stern drives have special procedures to change rotation.

* AQ "non-hydraulic" series 270/280/290 Volvo stern drives require a trailering bracket to prevent damage to the tilt mechanism.

Simplified gear lube chart. or contact dealer.

* AQ series 270/280/290 and SX Volvo stern drives... Even Volvos need maintenance. 

* When trying to acquire parts; Volvo, like most other manufacturers, goes by either the serial number of the component and/or, for over ten years, a seven digit part number used on all of their assemblies. The out drive, transom shield, & engine each have an assembly part number sticker attached to the assembly.
