As a new owner, I have a bunch of quetions and stuff - this will be the first.

I got my boat about a month ago, and have been limited to driveway sailing with her. But in my adventures, I have discovered that the wind gauge doesn't work, and isn't snugly installed, so water is leaking into it.

It is an SR Mariner Gauge and they have gone out of business. Does anyone know the size of the bulkhead holes for the gauges, and have suggestions for other good gauges that fit the same opening?

SR Mariner still has a web site with some resources and they do repairs of their equipment. Here is a link to the manuals they have online. The manual should give you the hole size.

Welcome to the world of fixing deck leaks. This may be the first but it won't be the last.

Thanks to both of you for your input.

A part of me is thinking I should just make a wooden plug that I could screw a mount for a chartplotter onto... A chartplotter is cheaper than a wind guage (the boat was not equipped with the masthead unit for the wind gauge), and it would be a pretty cool toy.

A lot of people have done what you are describing, others made windows or portholes out of the old spot. I think this would be an ideal spot for a fishfinder/depth finder or chart plotter/GPS. Also possibly a knot meter if you're going to race.

Nautiduck,

Thanks for the link. I have SR Marine Depth and Knot Meters on my '89. Both units were inop when I bought the boat. I contacted Cory at SR Marine today and it sounds like he can refurbish and calibrate both units for less than $150.00 total. He was very helpful even giving me some directions on how to trouble shoot the units before sending them in for repair.

I learned something else from their site. I had two weird looking plastic plugs in my extra parts collection that came with the boat. Turns out these are dummy plugs that can be pushed into the opening when you need to remove the transducers for these two instruments. I'm thinking I might be able to remove the transducers while the boat is in the water. Not sure if I have enough guts to try this though.

Gary,
Unless you've got a huge pump ready to keep your boat off the bottom, I'd advise strongly against trying to remove your transducers while the boat is in the water. A two inch hole 3' below the water line (about right for our boats) will allow 136+ GPM, or over 7000 GPH, a boat with 3 2000 GPH pumps would sink because they couldn't keep up. I got these figures from this [url="http://www.oceanmarineservices.com/why_do_boats_sink.htm"]site[/url]. Scroll about half way down to view the table for various sized holes various depths below the waterline.

Jim:
Thanks for the idea with the knots meter - we already have a combined knot/log meter. I have seen a number of boats with acrylic "windows" in place of a gauge. I have an incling to replace my hatchboards with the acrylic hatches, and a 3" hole would negate the need for that in the eyes of herself, so you know what that means.

Gary,
How were the folks there to talk to? Being that I know nearly nothing about this stuff (and need good guidance) I am a little wary of calling. Maybe thats even more reason to call. Is there some kind of a regular service interval for these things that they should be sent out to be cleaned/serviced?

I pull my transducer out all the time while in the water when I need to clean it. It is no big deal, just have the plug ready. I can do it fast and only get about 1/2 gallon of water into the boat. I pump this into a bucket and mop up the rest.

But did you do it for the first time while it was in the water? It would seem prudent to learn how to do it without fear of sinking your boat in the process.

I removed the non-working depthfinder (SR Mariner) and replaced it with a fishfinder. I used a scroll saw to cut a circle out of Starboard and covered the hole that way. Then from inside the cabin and using the bolts that hold the circle on the outside of the cabin, I mounted a support (out of Starboard) with a RAM Swing Arm. The fishfinder swings out when I need it or I lock it in against the inside cabin bulkhead when not in use. Details and photos on my website.

Prospector,

The folks at SR Marine were great! I didn't have any of the Model #'s with me so Cory asked a few questions and was able to figure out which units I have on my boat. As I mentioned above he then proceeded to give me instructions on how to trouble shoot both instruments before sending them in for repair.

JimB,

Do you have the SR line of instruments? DO you just unscrew the retainer nut, pull out, and put plug in? Is there an O-Ring to worry about?

Just unscrew the retainer and pull the plug out, have the cork ready. Really, you can do it. There is no O ring. If you want to be super carefull, pull it out halfway, take a look, then push it back.

Mine is a transducer for the knot meter. My fishfinder shoots sound right through the hull.

I've done it underway, offshore, while sailing. You can see the bottom of the ocean through the little hole, pretty cool.
