If you would happen to want to play more radically with the cavitation height, probably the recommended safest way (especially when you might be trimming up and not watching the water pressure as much or if using a hydraulic jackplate) is with a low-water type of lower unit. Mine came with a CLE (Crescent leading edge), although I think the Sport master and Torque Master units offer low water pickups too...BUT, low water pickups (and different nose-cone & skeg shapes) present their own unique challenges too - especially in that they are easier to get sand in the pump near shore and of course sand bars. I was emphatically warned by the previous owner to be very careful - and I think I have been - but when I took the pump apart just before the event because it refused to pump on the flusher (takes a special nosecone flusher too since the intakes are on the bottom instead of the sides) I noticed that there was some sand in the passageways regardless of being careful. I don't think that it was enough to wreck the pump (but sure can't help longevity either) - and I suspect there's a small amount that goes through no matter how careful you are. High or low (motor height and/or water pickup), they both have unique challenges.
Usually raising beyond that 1 to 2 inch range isn't worth the extra expense of what you need to do it right vs. what you gain in mph for most of us. There's all kinds of (usually expensive) balancing factors that come into play when you experiment in that 65+ range and especially if trying for that magical 85+ "barrier". Chine walk (pad?), cavitation, torque effects of a usually longer slightly different shape but higher lower unit, etc., etc.,... (not that you were intending to go that far - just things to consider if you suddenly "got the bug")
(semi-related side-note: regardless whether you have high or low pickup, my face almost goes sickly green when I've seen certain "idiots" (for lack of a better description IMHO) next to me with their pontoon boat revved up in reverse to "un-beach" so they don't have to get out and push when taking off - the surrounding water turns brown with sand for quite some time after that - you just know if you start up, or were traveling past, even out a ways, that there's some sand (or worse) floating that will get sucked in (imagine what it's doing to their water pump!)!! Maybe nobody does that outside of this (sometimes silly) area?)
