Help to Interpret Oil Results on Detroit Diesel 671TA

Hello All,

Looking for some help on interpreting these oil results. I am considering buying a boat with these two engines. Im not sure how to read these reports. What I have been told is that the owner did not drive the boat much and hence did not change the oil since 2020. I am the buyer and do not know if these reports are typical from not changing the oil or if something more serious is going on. I will tip with the best help.
