• SLX Series: Premium features may include more complex electronics and entertainment systems

• Sundancer Series: Cabin cruisers require additional focus on head, galley, and sleeping area systems

Seasonal Preparation Tips

Proper pre-season maintenance extends boat life and ensures safety on the water. Create a maintenance log to track completed items and schedule professional services. Take photos of any concerns to discuss with your service technician.

Consider scheduling a professional inspection if:

• Your boat has been stored for an extended period

• You notice any unusual wear or damage

• It's been more than a year since professional service

• You're unsure about any maintenance procedures
