2012 Mercury Black Scorpion 350 Cat/O2 sensor delete

I just acquired a 2012 Supreme V226 that has been throwing a O2 sensor code, it apparently is a somewhat common problem on the Black Scorpions that had the emission garbage on them. I was curious how to tell if the motor is a Scorpion ES DTC, or a Scorpion DTS? I have been looking to possibly delete the CAT system and have found some tuners at will bypass the O2 sensors like this one

Or this one

Also are there just resistors I can put in place of the O2 sensors?

The boat has been throwing the same O2 sensor code for years apparently and the boat runs fun and never goes into a limp mode. It has been to a very reputable Merc shop locally and they are stumped... I know they can’t delete but I sure can.


Thanks!
