The hull is an Alumacraft 1236 with a 15 inch transom,
the outboard used is a 20 inch shaft 2 hp Honda, jack it up guys.

For your basic setup, a flat bottom jon with a stock prop,
using the same style beater plate you could get by
mounting the outboard with the cav plate 3/8 to 1/2 inch
above the bottom of the hull. That would be close enough for your purposes.

My guess based on past boats I've owned is yes.
Balancing the load, trim angle of the outboard and propeller
can all be tweaked to improve performance.
But, is it worth the effort if all you are doing is fishing?

Not like we're discussing racing for money here... Wink

I have the same set up. I have been wanting to try this myself mainly to run shallower.  Let me know what you find out. I have been tossing around the idea of making a jack plate.
