A 10w-60 synth SM/CF A3/B3. Thinking of running it in a 5.0 Mercruiser EFI, oci 40-60 hrs. What's your verdict?

What does your manual say?

Here, they want a 25w-40 changed every 50 hrs.

Many guys just run a mineral 15w-40.

It will be a 40 grade before you get too many hours on it.

Start with a stout 40 grade, such as suggested above.

It looks just fine for 50 hours use.

0W40 would be the thickest that I would go in Arctic conditions.

Aren't we talking about a 305 cu. in. Chevy engine that runs at a steadily higher RPM as a car/truck but in the cooler temp range? Then why are the boat engine manufacturers stuck in the 1960's for super thick oil viscosity?

Because they don't care about incremental gains in fuel economy and because boat engines run at max HP or close to it for extended periods. Additive packages in low viscosity oils are fine but viscosity is still the first line of defense against wear.

15W-40 HDEO will do fine.

1. A boat at cruising is like towing a heavy trailer uphill in second gear.

2. Oil temps on the models not fortunate enough to have an oil cooler are severe.

3. Oil temps on models with an oil cooler can still be severe.

4. Volvo Penta tried to get away with using a synthetic SAE 30 diesel engine oil for the Chevy small block based engines and got bad wear results.

20w50 is as good as it gets unless living in ice.

my engine has no oil cooler, and volvo recommends 15w50 mineral or 15w40 diesel VDS-3 rated oil for this engine up until 2008 (when they added catalysts).
So I bought volvo penta VDS-3 oil as it was cheaper (????) than Mobil delvac MX that I used to run.
Makes me think volvo is aiming at minimum 40 hot viscosity and a diesel add pack for wear.
Mercruiser seem to use oil coolers and their standard oil is the 25w40 so it seems fair to say the gm v8 need a 40, at least.

Turbine oil is very thin, why doesn't this theory apply to them?

Why should it? depends on the film reqs and also the surface properties of the parts. Maybe the bearings in a comp is tight and controlled temp?

Apples to oranges.

Just the mere fact that a turbine engine has no reciprocating parts is a major factor. There are 1000 others.
