ST60 Thruhull Speed & Depth Transducer Problem

[Kings Gambit]

Here's the ST60 unit I removed as it normally appears.

Here's how it came apart the last time I removed it; notice the corrosion of the wires on the left (top) part of the unit.

Here it is in two pieces, lateral view.

Here's the replacement unit PN that fits the thru-hull.

Here's a link to the unit at Airmar.

Ah, that's interesting. The barrel of the transducer unscrews in the middle, right? Its not sealed in anyway? If that's the case I guess I can take a look inside and see whats going on? Thanks for taking the time to do that.

It does not screw; it's close tolerance push-in; i.e., friction. If you pull it apart as shown, you'll break what is left of the wires. It'll be kaput!

Not entirely true; I just replaced mine a few weeks ago. The paddlewheel (transducer) and blank fit the existing thru-hull perfectly.

Correct, the EBay item and the photos you posted show a transducer identical to the current one I have.

Ok, understood, thanx again.

Whoa! Stop both engines. The photo and link that Kings Gambit posted is for an Airmar ST800 Smart Sensor. That is a speed and temperature sensor. Your original post states speed and depth and if so then it will also have the temperature function. This sensor (transducer) is know as a triducer and is an Airmar DST800 Smart Sensor. It comes in both a NMEA 0183 or NMEA 2000 version.
Determine your model accurately, as Raymarine and Airmar part numbers/models/etc can really make things confusing.

That's an understatement!! LOL

Thanks for pointing that out, the display at the helm is a ST60, I thought ( possibly wrongly ) there is another transducer for depth, to be honest Ive not taken much notice - When it needs replacing I will do as you say.
