Oh, really So, if it has GPS it'll generate boat speed...??You can get your speed (over ground anyway) from the GPS.
Thanks, I may go that route but I wanted the transducer to also measure boat speed and water temp, although water temp is more of a luxury. The transducer will need to be in the water....ie...wet :laugher
The two useless gauges I currently have are for speed and depth. I've been using a phone app for speed and I assume it's accurate but I'm always scared of getting the phone wet or worse..
I figured buying one of the fishfinders would get me GPS, speed and depth for under $500.
I was going to remove the old instruments and make a nice teak plate to cover the old holes and flush mount the fish finder into the teak.
While I appreciate everyone's feedback, sometimes this site is frustrating. It's like nobody looks at a link or picture. You can buy fish finders that have a transom mounted "gadget" that does speed, depth and water temp all in one unit.
My basic questions was if these worked on sailboats and how would one install the sensor without drilling holes......ie....5200 adhesive... It appears not.
I'm gong to pull out the broken old instruments and find a GPS fish finder with depth and be done with it, I don't need exact speed, I don't need water temp, its accuracy can't be any worse than my phone.
I'll buy something I can mount to the inside of the hull.
FWIW, this site's picture attachment feature is very flaky. It does not display properly on some computer browsers and cell phones. On my phone, it displays, but is SO TINY, and sometimes the black space is all that shows up because the picture itself is off the screen to the side with no way to pan it onto the screen. (As soon as you touch the screen, it disappers.) Some other embedded pictures don't even show up, and you can't tell that they are missing.While I appreciate everyone's feedback, sometimes this site is frustrating.

chip-Let us know how it goes azguy. I've got a shoot-thru-hull transducer and so far haven't been able to find a place to get a reading using the bag of water trick, squishing it down in wax, or placing it into my bilge after intentionally filling it with water. My next plan is to find an inconspicuous place to sand off the interior hull texture to see if that does anything. People on the Catalina Direct forums have gotten them to work though, so I know it's possible.
