Apex manual

[Revman]

Hello There, I recently purchased a 97 Ski nautique with the Apex 320 hp motor but don't have the maintenance manual for the Engine, I would like to do a oil change and filter but don't know what type to use?, Does anyone have any idea where I could find a manual for this engine?
Thanks.

RE: Apex manual

Look to the menu on the left hand side of the screen, go to Downloads, Owners Manuals, then you should see the 1997 CC Manual. Starting on page 48 is the manual for the engine, which includes the Apex.
