Lots of oils out there to do a good job and I have tried a lot of them over the years and for stock engines they work just fine. But for the bigger HP engines I have settled on Neo P40 for my 850's and I really like it.

Since I had my first boat in 1987, I've seen where Mercury has recommended straight 40 weight for over 50 degree temps. Now, they also recommend their 25-40 oil. Don't see how you can go wrong with a quality straight 40 weight, though.

I use 20 - 50 Royal purple, but as you read there are lots of choices. The most favored, I believe is 20 - 50 mobil 1.
Lots of reading OIL Links:
Start on last page of some and work towards front for current stuff, but read Hydocruiser stuff at beginning.
