A few addition things to be aware of...

Am going with the 801E unit, amortized over the 40 years I plan on keeping this thing it's not much more
1) As far as I know, since the late 2000's (2007/2008) all Icom remote
tuners (AT-130, AT-140, and AT-141) have had their RF Ground connection DC isolated....
(So there would be no difference there...)
2) You will NOT install / connect any "RF Ground Strap" between the transceiver (neither M-802 or M-801E) and antenna tuner unit, nor to the vessel's RF Ground / Antenna Ground system...despite what the manual says...
The only RF Ground connection should be at the remote
tuner's "grd" lug...
(Here again there would be no difference...)
3) DC negative ground has not been a cause of any electrolysis problems on any vessels that I'm aware of....and I've been using/installing HF radios on-board for almost 40 years now....
(So, unless you have an aluminum hull
. here again I would have no worries...alum hulled boats are different!!)
4) No argument that the M-801E is better suited to a harsh environment
and is probably even "splash-proof"....but as long as you keep the main transceiver unit away from direct spray / water
/ etc....the humid sea air will not cause any issues for an M-802....
(But, if you are really thinking that you're going to be using the same radio 40 years from know....you are a fine man, and one after my own heart...as I have some ham radios at home, on-shore, that I still use regularly, and still work
better than many of the pricey new radios....and one of them I bought new in 1977/78, over 35 years ago!!!
But, understand that is an exception and not the rule!!!)
5) If you choose the M-801E, PLEASE confirm with the seller that the radio is "opened-up" for all-band transmit, as the factory-stock M-801E supposedly is NOT capable of transmitting on the ham radio frequencies (with the exception of 160m and 17m)
6) Which ever model you choose, you should have a look at the operating / programming videos I posted earlier...they will help explain what the manual is quite inept at...
7) And, should you wish to read the M-801E manual....here it is...
And, click the link to the "Instruction Manual" here, M-802 manual...

I do hope this helps...
