BTW, in case you are wondering- the reason for sensing the Sea Water pump is in case it overheats, say from a stuck impeller or a closed / clogged sea-strainer. Likewise, if the exhaust / sea water mixing point is more then a few of degrees above the incoming sea water temperature, again something is wrong in the raw water cooling system.
Here you can see the 4 'tab' mounted senders from begging to end.. I took a short length of copper tubing, flattened one end using the Vice Grips. Then inserting the sender into the other end I again used the Vice Grips to crimp them in. Will drill holes into them once I decide which size is needed for each application.

I briefly thought about soldering them, but I am not sure what would happen to the senders them self under a gas torch Crimping will have to do. And I made sure to use good shrink wrap, the stuff with self-melting glue inside.
For the Kubota Engine temperature sender I used a 1/4" copper tubing to 3/8" MPT fitting. There is a flange inside the fitting that needs to be reamed or drilled out to allow for the sender to pass through and get 'into' the cooling water.
