I'm looking at a 225 HP VMAX HPDI 2004, with less that 150 hours on it.

I know there have been several issues with the early HPDI, specially the big block, but I haven't been able to find a list of the upgrades recommended by Yamaha.
I know the updated oil pump is installed (to prevent foul plugs), but what else should I look for?

Thanks
