Whatisit?

I am going to call this a whatisit?

Much different than a whatchamacallit!

It looks to be a through the hull depth, speed, temp something?

Has 2 wires; red and black.

Just curious if someone knows. Looks like it makes a big hole in the bottom of boat, so, I not want to touch it until the boat is out of the water.

Mostly just scarylookin'........

Probably a knotmeter since depth sounders usually are not removable.

I'd call that a hole waiting to happen.

That was on my previously owned boat - a 1973 C&C Shark 24.
Here's a link to the same part. Made by Moore Electronics.

Yep, this is in a 1973 Santana 21' back when they made big bulky stuff that requires big holes!

So, I guess it actually does go through the hull and not shoot through the hull?

Dang, I hate drilling holes in a boat, especially when it is below the waterline.

Thanks

There are few if any knotmeters that do not require a thru-hull fitting.. some sounders can be set up to shoot through the hull (at some cost in range)

Theoretically a Doppler-shift style ultrasonic knotmeter sensing through the hull is possible... and I think some were marketed at one point but AFAIK never really caught on. I suspect the hull thickness near the bottom of the hull is a bit too much in most cases and cored hulls would be worse.

Looks like part of a pipe bomb

Definitely a knot meter transducer...I have one still in use on my Ranger 23. But mine doesn't look so bad...
