Troubleshooting & FAQ
How do I confirm this cover fits my engine?
This cover offers a universal fit for most 4-stroke outboard motors from 5 to 20 HP, including models from Mercury, Yamaha, and Honda. Its dimensions are 59" × 49". We recommend measuring your motor to ensure it fits within these dimensions, especially for older or uniquely shaped engines.
