Can Anybody Please Tell Me What This Is?

Poked camera around in places I can't poke my head in and see for myself, and I found this.

Tried to find such an animal in the West's catalog, with no luck.

Thanks.

Depth transducer?

I think it's a transducer for maybe a knotmeter or depth gauge.

If you replace it, make sure to get something in a light tan so it won't clash with your pimpin' carpet!

Looks like a depth sounder to me.

Looks like it might be a removable transducer for a speedo/log maybe. If you already have one why are you looking for another?

Looks like duct tape. What do I win?

A date with Gumby and free roll of duct tape?

Transducer, awesome. Just have to trace that line, lose the duct tape.

I found a roll of blue carpet below the v-berth. That 70's orange has to go.

Lots of plaid and orange in the cabin.

Not looking for another. Was simply trying to find a pic to match so I could tell what it is. Until today, I didn’t know I had a transducer. There’s no instrument that I can find.

Removable?

Yes, and the duct tape has to go, too, along with that carpet.

I’ll be tracing that line this evening after work. It’s only about six-eight feet to the panel. Hoping I find its bitter end there.

Boat’s hitting the water next week.

I am pretty sure it is a knotmeter transducer. I have a Signet knotmeter in my Pearson 10M that is removable with the metal bracket on top that allows for the removal. The screwable lid below the metal bracket is what screws the transducer on to the tube and hold it there water tight.

Be careful while removing the transducer while in the water! You get a good gush and run a risk of sinking your boat if not plugged. I use a similar shaped plastic plug to cover the hole while I clean the transducer that has been removed. After cleaning I pull out the plug (which also has a similar screw type head) and replace the transducer. This is common design for knotmeters.

If you don't have a meter, how do you measure boat speed on your boat? GPS? Technically there are only two wires coming out of the Knotmeter transducer. The cable is shielded.

Hope that helps.

There’s a compass, tilt meter, and I think there is a knotmeter in the middle. OK, that splains things lots for me.

I won’t touch it, period.

Haven’t had this boat in the water yet. It’s been trailered since 2008.

I’m actively shopping for a thru-hull transducer type Depth Meter. Reasonably priced one in the 2010 West catalog. Maybe I can install its transducer on the opposite side of the boat, exactly in the same location as this transducer. Would be an excellent place, right below the starboard salon.

I do have a hand-held GPS Magellan that I was going to hook to a computer to use as a chartplotter, using the Polar View software/charts. If that works fine, I won’t have to buy a dedicated chart plotter.

Thanks for your insights guys. I built a one-pager punchlist of things to do last night. Going to be a very busy weekend.
