| As the name implies, transom mount transducers are
installed on the boat’s transom, directly in the water and typically
sticking a little below the hull. Transom mounts are composed of plastic
and tend to be less expensive than other transducers. |

Transom mount transducers are recommended for planing hulls of less than 27
feet (8 meters), such as personal watercraft and powerboats with outboard,
inboard-outboard and jet drives. They are not recommended for large or twin
screw inboard boats because aerated water from the propeller reduces
performance. They are also not recommended for operation at very high speeds.
Transom mounts adjust to transom angles from 3° – 16°. For angles greater
than 16°, a tapered plastic, wood or metal shim will be needed. However, the
transducer should be adjusted so it is angled slightly forward when the boat is
in the water.
