Joe Krasko runs a 90 (think it's actually an 85, but whatever) on his hyperlift and could probably offer some input on prop selection if he reads this. He's experimented with props a good bit from what I recall.

mercury vengeance is the crappiest ss prop merc makes. Basically an aluminum prop mold poured in ss.
Try a laser2 or high five
If you were closer I have a high five 23p you could try. High five props are smaller diameter so it runs like a 21p
