Other transducer types are also available for specific requirements. For further
details, contact your local Raymarine dealer.
For accurate speed readings the transducer should be sited within the clear water
flow areas indicated by the shaded areas in the following diagram.
Transducer siting
The transducer should also:
• Be ahead of the propellers (by a minimum of 10% of the water line length).
• Be at least 6 in (150 mm) away from the keel (ideally ahead of the keel if a sail-
ing yacht).
• Be as near as possible to the center line of the vessel.
• Be clear of other through-hull fittings or projections.
• Have sufficient clearance inside the hull to fit the nut.
• Have 4 in (100 mm) of headroom to allow for withdrawal.
