It's typically a few rows over from auto section with the boating and marine stuff.The WM here must not carry it any more.

I don't think any Mercury or Volvo inboard/outboard stern drive engine comes with an oil cooler and if so it's not anywhere near all models and more likely special production racing engines.Boats have nearly unlimited cooling and oil coolers, with usually ~160F thermostats. They don't get as hot as car engines in my experience. If you exceed 212F in the heads/jackets you see steam behind the boat and you know you have a problem...as the raw water is boiling before it leaves with the exhaust. While marine engines are worked hard...they are kept cool if everything is working correctly.
And neither is temperature a problem here nor has the OP indicated anything of the sort.I don't think any Mercury or Volvo inboard/outboard stern drive engine comes with an oil cooler and if so it's not anywhere near all models and more likely special production racing engines.
This. I run 5W-40 in our GT40, we have the same boat as the OP as well, but it has a 5.0L Ford in it (302) and it gets 10W-30 from the marina IIRC.A lot of boat owners use 15W40 gas & diesel rated oil. Or 5W40 synthetic oil.

(EDIT) @DriveHardI would most humbly disagree and say most of them DO come with an oil cooler. Actually a lot of them come with power steering coolers as well!
That's what I remember too but I got out of boating a long time ago and things change. Kinda why having an oil cooler and oil temperature is important.....(EDIT) @DriveHard
Power steering coolers are a given but few oil coolers.
I just looked up parts numbers. I can see it was hit or miss if an oil cooler was used. But a huge amount do not on this list.
I've been boating for 4+ decades and never had one or remember one but I see some engines (at least until up to the 2008 parts list did have them but a large number did not. I do not know if those that do, I suspect maybe were higher performance (racing) engines maybe?

If a boat has an engine oil cooler it would be easy to tell. there would be an adapter with hoses right at the oil filter. I never saw one on any boat I or anyone I know. Though you made a good point. There must be some, I just dont know what applications they are used for.
Why?
Racing engine/ Classic car. Why not? Loaded with good stuff. Looks much better than all the generic 30 sae out there like supertec.Why?
Not a great idea to run race oil.
Race oils and classic car oils are different.Racing engine/ Classic car. Why not? Loaded with good stuff. Looks much better than all the generic 30 sae out there like supertec.
