No, sorry there's not. There once was one, but now it's gone.<br /><br />You can purchase a parts manual though from these fine dealers:<br />TheOutboardWizard<br />Mastertech<br />Marine Engine<br />Ken Cook <br />Those have breakdowns of each component and their part numbers. The service manual has some exploded diagrams, but fewer. It is more useful though.<br />Also, check ebay.
