My unit shows 83/200 KHz as my choices

If I want to raise the power on my unit, do I just need
To get a new transducer for higher KHz?

And if so, will this help my resolution for
Side scan of fish on bottom?

Thx for help

You cannot add any frequencies or any more power to the units.

The most you can do with that model is change to the XHS 9 HDSI 180 T to get sharper images due to the longer Imaging piezos. IF you have the SI model.

You can get more depth capability by using a 50/200 kHz transducer and changing to that frequency setting.
