all this work for a boat ride!

Can you elaborate a little more on this...

What do you mean plywood to suspend?

How is the high speed running?

Approx. how far back did you do this?

I am sure the temp. reading does not read accurate.

Do you have any pictures.

Thanks,

I epoxied mine the the hull to read through. About 6 inches off centerline and as far back as I could. After the boat is in the water about ten minutes it reads the temperature of the water closely. I have had no problems with this method of mounting the transducer. My friend just mounted one on the transom and at high speeds loses depth readings.

Sent PM before checking the board, probably left others hanging - sorry.

Everything is great except temp. if my PM explains it better, would you cut and paste it? My typing stinks and time is short today - thanks.

Its been awhile, and progress has been a bit slow.

First thanks for all the ideas on the placement of the transducer on my boat. Some very interesting and innovative ideas that have me thinking on how I will want to mont my ducer. For now I think I will fill the 3 existing holes in and start fresh with a new one.
My materials finely arrived so I could start laminating the new core into the boat. I decided to use epoxy resin from US Composites for the build.

For the transom

I really wanted to enclose the transom, and put on a Hermco outboard bracket,but unforchantly that will not be in my budget at this current time, so I decided to leave it open.

After I made a template out of masonite board I cut two pieces of 3/4in marine ply, and bonded them together using a think-end epoxy putty, that was clamped together using drywall screws and wights.

To clamp the new core into the hull I decided to use 2x4 with carriage bolts, and drywall screws, to sandwich it together. I also decided to take the advice of a fellow form member and raise the transom from 25in to 30in.

Bolting the transom together was a bit of a struggle doing it by myself, especially getting the carriage bolts lined up level, but it worked out ok in the end.

The next day I decided to prepare for the 1708 cloth by making some fillets around the perimeter, of the newly installed core.

Next came 3 layers of biaxial tape over the fillets.

I was not completely happy with the uneven suffice of the top on the new core. I wanted to make it level before I layed up the 1708 cloth. So I decided to make up a batch of thicken epoxy to make the surface even, before the cloth layup.

thats all for now
