Poking around I came across these things under the forward section of the starboard settee. Both say "Hand tight" .
They are your transducers for your depthsounder and knot meter.
One is probably the depth gauge transducer , other may be the knot meter transducer but usually it's in the v-berth.
Hi,
depth and knot meters, mine are at the same place.
Hopefully you also have a dummy plug. It would be of the same style and shape allowing for removal
of your existing depth or speed for maintenance or cleaning while in the water.
Steve
Thanks to all who replied. I would not have guessed those.
Steve - I'll look around for a dummy plug.
Steve : The top one in the picture is your knot log transducer and the bottom one is the depth transducer.
From the looks of them I'd say you have Data Marine instruments. You definitely need to find that dummy plug!!
A thought
If I rember right, if that pin comes out, the speed log transducer will come out. Good to put a safety wire on. Had a friends boat sink (at the dock) when that happened. He hasn't found the pin yet.

You're correct Ron, I do have Datamarine instruments.

Now
that is good to know!
Steve : I believe that the pin on my Data Marine knot log is such that I don't need a safety on it.
Haven't had a problem in 26 years.

Thanks Ron. When I get up to the boat this weekend I'll take a closer look. And hopefully I'll find the plug somewhere.
Steve : Forgot to mention that the Knot log pin has a hole in one end.
If you look at your picture you can see the 1" ring clip that is thru that hole to keep it from coming out (until you remove that pin!).
Just a heads up in case you do pull the speed transducer for cleaning
It can go back in to ways, one of those 180' deg wrong. It is not marked clearly, so do pay attention to which way the paddle wheel is oriented.

I noticed that. I assume that is what Jim was referring to when he suggested attaching a safety wire?

Thanks for that tip. I guess I'll save the photo for reference.
One word of caution: If you ever pull one of those for service do it when the admiral is not onboard. They tend to get very excited when you pull it out and the water gushes in, if only for a second or two.

Well, thanks for that but since I'm single I guess that won't be a problem. Nevertheless, I think I would be very careful pulling one of those out since I would probably get a bit excited if water started to gush in.
Steve,

Good guys.
If you need them.
Steve : FYI, I've never had a problem with either the Data Marine knot log speed or the depth finder from day ONE!! I have sent my wind instrument to DMI for repair a few years back.
DMI are good guys (not cheap) and are the only people that I know of that can/will repair Data Marine instruments!!
A few thoughts!
Stu, Ron, thanks very much for the head's up on DMI Marine. Could be very useful, they're only a couple hours from me too.
