Stern drives have always been problematic in terms of fouling. Due to the many different metals they are composed of, their moving parts and soft bellows, conventional copper impregnated antifouling paints are not an option.
Sonihull coupled with the Stern Drive & SailDrive Adaptor offers great protection to this important part of the boat that is prone to fouling. Results show an impressive average of 80% reduction in fouling.
The device enables a Sonihull transducer to be simply screwed in, so that ultrasonic signals can be directly injected into the stern drive. The Stern Drive & SailDrive Adaptor mounts via the 16-18mm bolt found in the fixed end of the stern drive leg steering ram.
