By this time, you've already seen the boat, and no doubt have found the amswers you were looking for....
So why am I bothering to answer you???
Simply for clarification and education....
1) Eric is correct the radio is an Icom
IC-725, ham radio transceiver.
2) And, Bill is correct that the manual tuner is an older MFJ.
3) However, what was not mentioned:
a) The IC-725 was without a doubt the worst HF ham rig Icom
It was an entry-level radio with a poor rec front-end and if stages....with poor IMD specs, etc...susceptable to overload, etc....no rf gain, etc...ineffective features, etc....poor longterm main ocsillator calibration, etc..etc.
And, its transmit specs are also crap!!!
I've only heard a 725 on-the-air a few times in recent years (thank goodness), but when you hear one you'll know it...
The vast difference between the 725 and the remarkable IC-735, is unbelieveable!!!
(Anyone who's used a 735, knows that it is a great little radio...and even 20 years on, can still compete well with other "modern" rigs!!!)
b) Depending on the antenna
used (assuming some type of insulated backstay, or wire, or whip) with the set-up pictured, the amount of RF (and RFI) floating around the Nav Station is going to be quite high, and problematic!!!
Severe distortion, and/or radio transmt issues are the usual result of having a random-length end-fed wire antenna
so close to the radio, microphone, etc...
c) the fact that the listing mentioned "single sideband radio", and they were referring to the IC-725, tells me that someone was seriously stretching the bounds of "ethical advertizing".....
d) If you combine these 3 items (a,b, and c)....you come up with:
--- a not-so-good radio
--- a piss-poor installation
--- deceptive advertizing
And, these add up to a warning to either steer clear of this boat, or be aware that much of what you wil be told by the seller/broker will be, at best, an exaggeration. And, at worst, staight-out lies...
I do hope this helps...
