Do the valvetrain around 200-250 hours,then rebuild the whole thing at 500-600.That is the way I would do it. I know others would not go that long and most will just run it till it blows. I run my stuff hard but I don't try to kill it. I have seen 500efi's go over 1000 hours with nothing but oil changes but I would never push them that long.

Yea...100hp x 2 is alot... I kinda figured that... but I wasn't sure what the difference was as far as wear and tare. But you gotta pay if you wanna play!!!

Really depends on how it is treated. We have seen 500efi and Hp500 go 600-1000 hours before rebuild. However with any racing motor plan on replacing the springs about 250 hours, valves/springs 500 hours youget the idea.
So the 525efi is a better motor, so I would expect the same if not better.

Well I'll be heading to the New Orleans Boat show this weekend so I'll get some input form the dealers and maybe the Merc guys will be there too so I can see what they have to say...but real world advice and experience is more important than a sales pitch to me...Thanks for all the info

496HO is the way to go, but you should buy the 400SS not the 370SS.....

I repowered this past summer with 496HO's 425HP and the complete cockpit is at the uphostery shop as we speak getting redone....
