ST800 Transducers

The ST800 replaced the ST600 for Raymarine products, using the same P120/B120 valve housings (2" OD). The ST800 has a rounded top cap with a side exit for the cable.

The paddlewheel kit for the ST800 is the 33-493-01 and is not the same as used on the ST600 (the wheel and shaft are the same but the O-rings differ).

The ST800 is available for Raymarine ST40/60 instruments (ST800-P-FISO & ST800-B-FISO), ST50 instruments (ST800-P-5 & ST800-B-5) and DSM300 sounders (ST800-P-RAY & ST800-B-RAY; Y-Cable needed).
