Sure, but in boat use the engine will be run much harder for much longer than it will be in any road vehicle.
Comparing apples to oranges.
I used to drive my Acura TL-S back and forth lower California to the very top of Idaho, 1420 miles, average speed 75 to 85mph only stop for fuel, 18 hours straight on 5w20 conventional. Drove thru Montana, Utah, Nevada, and California desert in the summer. Oil is not an issue, unless your engine runs out of it!
That said, I would run 10w30 in the lower states any time of the year provided it was synthetic.
That's nothing like marine use in terms of the power the engine will be asked to put out for any sustained period of time.
75-85 mph on the freeway is nothing.
Were you going 100-110 mph for a similar period, then you'd have a good point.
