Performance & Practical Benefits

By sealing an open NMEA 2000 port, this weather cap helps prevent corrosion and the intermittent network faults that often come with water intrusion. It keeps the VesselView’s connector clean and ready for future use and stops accidental debris entry during maintenance, storage, or daily boating. It’s a small part that protects a very important connection.

Why Buy OEM

Fit and sealing matter when protecting an N2K port. Mercury’s OEM weather cap matches the connector exactly, ensuring a tight seal that aftermarket caps often fail to provide. The proper material and shape keep the port protected without loosening or cracking over time.
