Just wondered if the Panel!! would know if its possible to fit a transom mounted transducer while the boat is in the water, I think I remember seeing a mounting bracket that can slide up or down as required.

if you are drilling a hole in a transom underwater then I wouldn't (because I couldn't seal it properly and would be sealing in water too!) - if you are not then I can't see the problem.
personally I would use silicon sealant to stick it on the inside of the hull somewhere (assuming it's single skin GRP) as a temporary measure then remove, clean off and fit th ethe transom properly when you next lift out.

To see if it will work through the hull just use BluTack to press it firmly in place then see if you get a reading.

get some of the fat people, mentioned in other posts to stand on the foredeck till your transom is out of the water then you can fit it

Good idea I know lots of fat people, mind you I like the blue tack idea I might try that one first..... /forums/images/graemlins/grin.gif

When trying to set my e/s transducer in a suitable location so that it would work well, I found blue tack wouldn't allow it to work... maybe it was just me, but couldn't get anything. Went for it and installed the in-hull kit with the oil... as soon as connecting it all up in the oil it was absolutely fine. No problems since. The benefit to the oil in a tube is you can easily clean/replace if necessary... once bonded to the hull you probably aren't going to separate the two again. BTW, you don't need to buy a specific kit - its fairly straight forward to make one yourself.

Can you give me some more details as I now believe the transducer has to be suspended in liquid for it to work is that right?

no
sailing craft have difficulty finding a flattish section of hull to attach the transducer so they get around the problem by attaching a hollow tube vertically, sealing the edges and filling with oil (or water) then suspending the trasducer in it so that it is horizontal to the bottom.
most powerboats can find a flat enough area that a good (air free) blob of silicon will allow the transducer to he installed 'flat'. Note I only recomend silicon like this to you as a temporary measure; if you are doin it this way permenantly epoxy or at least sikaflex would be much better.

Thanks for clearing that up for me........

Duncan is spot on in his answer... the trick being the air free bond/seal (oil allows this easily as all bubbles rise to the top above the transducer), but this also includes the hull not having any air bubbles in either. You obviously want it to be positioned as near to vertical as possible or the depth readings could be a bit exagerated. I've posted the pic of the tube setup, but you shouldn't need it in a mobo - I hadn't realised we were talking of a mobo /forums/images/graemlins/smile.gif
