Should boats be ran Wide Open Throtle ALL the time?

the basics>>> stock 496-525>>> No engine lives long with her throttles always aginst the firewall. Shure its o.k. to stretch her legs but their are more then 2 speeds, other than idle and WOT. Where is the illusive sweet spot, the spot where the engine is at max efficiency, sync and performance.
Lets say its a garden variety, run of the mill day on the lake or bay, smooth water and the boat is set up just right. I would
say 3400-3600rpm @ 50ish mph, boat lenght is 35 feet and 8000 lbs.

496 HO - owners manual says if you want longevity 3/4s throttle or less will give you the best chance of not beating the snot out of your engines. It is a machine - WOT all the time it will wear out fast and yes they do break. It aint a car and it is under constant load. Treat it with some respect.

On occasion I will stretch it's legs and go full throttle, but not for more than 10-20 seconds. I just think it is abusing the machine to run any harder than that for an extended period of time. Also hard on valve springs on my 500 efi's.
