Old through-hull holes brand name model?

[steveinusa]

The Through-hull holes have dummy plugs in them where the old transducers went. Are there new replacements that i can just slip in from say raymarine etc? What brand are these any ideas? Thanks.
Just discovered they are old SR mariner Nav-5 transducers. Replacements that fit the holes?

I have the same issue...

Our old SR Mariner instruments were toast. I wanted to find replacements that would fit the old holes but everything was larger diameter. Also, many are now a single unit (speed, depth, temp) and NEMA200 that can talk to a variety of displays.

I'm now questioning whether I really need speed and temp (have GPS and a toe to tell temp with). Then I could use a "shoot through hull" transducer and eliminate two holes in my hull.

Too many choices....

Oh - and don't laugh.

Last season I used an inexpensive fish finder. Epoxied the transducer to the inside of the hull. It worked perfectly and even gave bottom contour info (as well as fish location and size).

I'm now questioning what advantage a bazillion dollar Raymarine (or other) dept unit has?

I even found a unit that flush mounted in a teak panel that covers the old SR mariner holes. But - it's not "yachty"

I was thinking same thing. And the toe is a cheap temperature sensor.

How about using a bucket, grabbing some water and testing it? Toe, finger, thermometer. No need to deploy the boarding ladder (unless you have a walk through transom). Your boat, your choice.

I used a fish finder on the last 2 boats. It works great and I intend to add one to our newest boat. I like seeing a trend for bottom countours and I really like fish.

LOL... what is "yachty" exactly?

It's when the other sailors don't snicker.
The Raymarine addicts chuckled at my fish finder. ??

That beautiful wood panel looks very yacht y to me!
What kind of wood is it? Very nice finish.
BTW ,what do you do with two yacthits?

Actually, he kept them... just so he could be called "Commodore".

Nice to have back up navigation equipment if for some reason you lose gps function. The knot meter/log can be useful for navigation. If you race, knot meter also important for fine tuning trim. The temp sensor is useful in racing when you are looking for certain currents like the gulfstream.

I do like the way that panel turned out. Covers up those two huge holes and still space for something else. I made it from 3/8 marine ply that is faced with teak. Used Epifines "wood finish" (5 coats, thinned 50%, 25%, 10%, 0, 0). It's attached with 3M commercial grade mounting tape. Love that stuff. It's mildly acid based so it's almost a structural bond, unaffected by moisture or temperature. It's about 1/32 thick so you can use a long razor knife to separate it if needed.

Two yachts? Who, me?
