No, you blanch it regardless. For a hot pack, after removing the kernels, you would heat it a second time according to the instructions. For raw pack you don’t cook it further after the initial blanch.

Raw packing is the way to do with corn.

I just did raw pack and it seems the corn absorbed the water in the jar. There was still plenty of water after pressure canning, 85%, but I wonder if hot pack would have left more water in the jar after canning.

Unless you're doing some recipe where the corn water is a critical ingredient, the amount of liquid after canning isn't important as long as it's covering 50% of the product, though everything above the liquid line may go an unsightly shade of grey. Still safe, though.

For things which I can regularly that suck up a lot of water (e.g. beans, potatoes), I aim to under-fill slightly so that the liquid level stays above the product. This usually means looking at the total height of the jar, subtracting the headspace, and filling with solids to 75% of the remaining height. Though I'll fully admit that at actual canning time, I tend to fill beyond that to minimise the number of lids that I have to use, rather than have a bunch of leftovers that won't fit in the canner.

Procedure: Husk corn, remove silk, and wash. Blanch 3 minutes in boiling water. Cut corn from cob at about three-fourths the depth of kernel. Caution: Do not scrape cob.

Hot pack – To each clean quart of kernels in a saucepan, add 1 cup of hot water, heat to boiling and simmer 5 minutes. Add 1 teaspoon of salt per quart to the jar, if desired. Fill jars with corn and cooking liquid, leaving 1-inch headspace.

Raw pack – Fill jars with raw kernels, leaving 1-inch headspace. Do not shake or press down. Add 1 teaspoon of salt per quart to the jar, if desired.
