Also, heard that there is a plug that Humminbird provides ... is this true??

Half or more of your transducer should be below your hull, nothing you can do if your boat sit high in the water and your draft is minimal.

There is a rubber plug that comes with the unit. Install it in the space between the transducer and the bracket and this will take care of your rooster tail

It didn't come with the unit but just ordered it from hummingbird dealer free of charge. We'll see if it works

I switched over to a shoot though hull transducer, works much better at speed and no more screw holes in the transom.

Yes this is true. Depending on the degree of the dead rise you might and might not have an issue with a Rooster tailing coming off the transducer. Hummingbird does supply this plug for larger units with Down Scan or Side Scan but you can easily purchase this plug online or at your local Electronics store. The part number is Humminbird XNT Plug (540188-1)

and here is the link to Humminbird XNT Plug: http://www.humminbird.com/Products/Transducer-Plug/

The plug sits between your transducer and bracket which prevents the rooster tail from happening. If you want to make sure this is where the rooster tail is coming from. You can try electrical type around the gap between the bracket and transducer to see if that’s the cause but don’t expect the band aid to last.
