Outboard Maintenance FAQs

How often do I need to change the oil on my FourStroke or Verado outboard?

Every 100 hours or once yearly, whichever occurs first.

Where can I get factory Service manuals, Parts manuals, or Operation, Maintenance & Warranty manuals?

You can order all available literature online. You could also order all literature through any authorized Mercury dealer. Please have your outboard or sterndrive serial number before placing the order.

Where do I find maintenance and lubrication information for my engine?

The Operation, Maintenance & Warranty manual outlines the typical maintenance and lubrication items. If your manual is missing or damaged, please order online or through any authorized Mercury dealer. Please have your outboard or sterndrive serial number before placing the order.

What should I do to prepare my outboard engine for out-of-season storage or prolonged storage?

The major consideration in preparing your outboard for storage is to protect it from rust, corrosion, and damage caused by freezing water that may be trapped in the engine. We recommend taking your engine to an authorized Mercury dealer to perform the work. Damage from improper storage procedures is not covered under the Mercury Marine limited warranty policy. If you choose to perform the storage procedure, follow the storage procedures outlined in your Operation, Maintenance & Warranty manual.
