You dont go run your car at WOT because you drove all day in town at 700-2K RPM.

I think this falls in the same BS that says surfing causes the engine to run low on oil because of the way the boat is tilted. All BS if you ask me.

You need to WOT your boat once in a while same reason you do your car, to blow any small carbon buildups in the EGR system and intake system.
couple of thoughts on this:
there are several stories here of autocross guys that are running a particular hard track that sieze engines up running at very high rpm's, very high egt temps and when hitting long corners, the oil pickup loses the oil from it sloshing to the side. only takes a second when running hot/heavy to sieze an engine, so there is some precautions to be taken. If I fill my vdrive to the line when stationary, that red light on the lanyard kill switch never goes out when surfing. add a little above and it's fine. there's a range of oil levels on a dipstick. bet if you run toward the bottom, there's times when towing, especially when whipping tubers around that your engine pickup is empty.

there's nothing wrong with idling cars around all day in town and nothing in the owners manual will say differently, however some do list shorter intervals for maintenance for town driving vs highway driving for the reasons listed above, and it is a good idea to run the engine every so often, but every trip? nah. if you run your boat 3-4hrs at 2krpm's, that should work out to around 60mph on an average truck(estimate). that's 180-250 miles in a given day on the lake. bet most don't "blow" their trucks out at that interval and cars go 150k or better with just basic maintenance.
