We all have our opinions, yet not many, if at all, have witnessed bearing failure from oil unless super thick oil at very low temperatures.
So....that said....
My opinion where I feel comfortable is 190's-250 max. Anything higher should be running synthetic while looking to reduce temps. 300F should be a stop and change something now.
Some say 180-190 won't burn of condensation and etc, I say BS. LOL. It will at that temp but obviously not as fast as higher temps.
Around here, other than mid/late summer, some of our boats from the area have the opposite issue (ie: too cool) if running crossovers and no t-stats. Good luck getting your oil warm enough to even plain off. You should see the oil from these engines. Yuk !!!!!
We had 36" ice this winter.

PM sent. I'm calling the seller this evening and seriously considering an offer. It looks like the 6.2 is a good motor for my application. Cruising and swimming with the occasion fast run.

Thanks SB. I value your opinion.
Greg,
Sounds like you will be happy with the 6.2s - good cruising fuel GPH and probably up to 70 m.p.h. top end.
If you need more speed you might want to look for a different power package as the 6.2 is a pretty coordinated engine,
meaning you pretty much need to do head work, different intake and TB change, cam, and computer tune if you want more power.
Seems there is no one step magic beyond labbed props.
