Search Engine or Battery Operator's Manual

To obtain the operator's manuals, illustrated parts list or detailed help information for your Vanguard^® engine or battery, you can search by your engine or battery model number. This is an 11- or 12-digit number stamped into metal directly on your engine or battery.

• You must use the engine or battery Model, Type and Trim with dashes, e.g. 12H702-0505-01
• Use '-99' trim if the trim numbers (last 2 numbers) originally entered do not bring back results
• Do not include spaces after the numbers
• Add a leading '0' for a model number with 5 or less digits (must be 6 digits total prior to the first dash)
