R5 High Altitude Prop Pitch Mercruiser 6.2L 350HP

[bruceb58]

I have a 2017 R5 with the Mercruiser 6.2L 350HP engine.

I have not put it in the water yet but will be running it in Lake Tahoe at 6200'. It Currently has a 20" pitch Solas 4 blade front and 3 blade rear. I am anticipating this will be VERY underpropped.

Just wondering what others are using with this same boat/engine/drive combo at 6000' or thereabouts

Not really interested in what other boats and other combos are running.
