1021K Airguide Seaspeed Speedometer | Genuine Used Part

🔧 Product Description

Genuine Vintage Airguide Seaspeed Mechanical Boat Speedometer - Model: 1021K

A genuine used Airguide Seaspeed speedometer for vintage and classic boat instrument panels.

The gauge operates from pitot-generated water pressure and does not require an electronic sender. Exact speed range, face style and dash cut-out should be confirmed from the product photographs before installation because several Airguide Seaspeed versions used similar housings.
