I have an older (Ratheon) ST60 and have to replace the speed sensor and thru hull.
Is the current ST800 (Part E26031, ST800 P120) compatible with the old ST60?
HI Dehler41CR
Thank you for your enquiry.
The E26031 transducer can be used in place of the old style speed transducer, but note that the transducer housing will also need to be changed,because the current transducers have a flapper valve built into the housing which reduces the in-flow of water when the transducer insert is removed.
Note the through hull [censored] is the same size between the two housings.
Regards
