[CA] [CA11] Upgrading Analog transducer to work with wireless displays

[Sam_Labrador]

For a sailboat.

Bought the boat with an Airmar St300 though hull speed temp sensor. All wiring is broken. It appears to have been hardwired to a TackTick Speedmaster (a long discontinued product).

Would like to replace it with Speed/depth sensor for the current Raymarine wireless displays.

Which transducer should we buy which will fit in the current through-hull fitting and will work with for wireless?

How do we connect the transducer data to the "wireless" displays?

The DST 800-0 Plastic through hull? Part Number: A22111 seems to be the leading candidate. But we cannot find a dimensional diagram to see if it will fit the ST300 through hull fitting.

The description says, " direct connect to STng backbone". But we cannot find any wiring diagrams of this setup. Could we wire it directly to Raymarine Wireless T122 Micronet Wireless Interface?

Thanks community for your responses.
