We ski and don't go after high speed runs. My cavitation plate is above keel, but unknown how much. Engine is mounted in second to lowest position hole.

Is this a good setup?

I run a 4 blade 22" right now, but will try a 20" HighFive this weekend. 2.5 Fishin powerhead mounted on 2.4 Offshore mid and low CLE drive. Max rpm is 6500.

I would start with the prop shaft an inch below the pad.

since your not looking for all out speed which is 1 inch above bottom of boat (center pod ) you should set it dead even with the bottom , your hi five should be a great ski prop . also remember where ever your at keep your eye on water psi . TUNNEL

Tunnel T... I saw your old boat classified awhile back. I will drop motor to lowest position (only one set of holes left). Yep, water pressure is good on this one. I do keep a steady eye on it.

Adding an Allison hydrofoil (bow rise problem)

HighFive (20") cavitated/reved like hell. It has small exhaust vents. Hub is small and much have allowed extra (too much) ventilation. I think the hydrofoil will make a big difference.
