Fitech go street on a boat

I've searched but can't find any info on marine use. Does anyone know if this system can be used on a boat? The only potential issue I see is the O2 sensor since water runs through the exhaust on a boat. Will this system run without the O2 sensor or does anyone know of a solution? Surely someone has tried this system on a boat by now.

Spoiler

If you unplug the O2 sensor, the unit goes to its default learned tune.  Problem is how you get to that learned tune.

Yeah, I could see that being a problem. Can you set the tune with the handheld?

Yes, but no learning.

I have ran mean street 800 on my Chevy 454 jet boat and I use the 02 censor with “dry headers” And it has always been mean as hell and fires up as soon as I hit the crank I didn’t have my controller plugged in for over 6 months went and plugged it in and now she won’t fire and the controller is very dim even plugged into usb and says timeout or just reboots if I try to do anything so fitech sending a new one I’ll let u know the results but overall I love it and fuel consumption is way less than these guys running dual double pumpers.
