If you are good as is with 200 khz then that seems more than adequate considering yo are using a single element 600 watt P79.

And if you don't want a thru hull them you are limited either a 8 element 1 kw M260 in hull or the 1 kw transom mounted units.

Here are a few interesting videos.




50 & 200 kHz B164

200 kHz Tm260
