Looks like a mercury jet shaft is 20", can I put that on my 20'G3 without adjusting my transom? Or will I need a plate to raise it?

I would just use a manual jack plate.

Adjustment is nice....... and necessary if you plan to swap between a jet & prop. If just running a jet I would look at some heavy aluminum angle, 3" X 3" X 1/2". Once you get it set right you shouldn't need to change it. If you have a tunnel you can extend the roof of the tunnel over the foot with a rubber flap. This will allow some grace as to running the foot slightly higher.
If no tunnel then a piece of UHMW will help
Lifts are handy whether manual or power, and they do allow some fine tuning, however they are heavy and the set back can be a big negative. Particularly so if the bottom is less the 6' wide. IMO
And spendy....."FREEDOM" Only those that are denied truly know what it means.

I measured then cut a piece of wood the proper height and thickness, then had someone weld for me a riser using 1/8" aluminum shaped like a "U", but squared off-or deep "channel". Inserted the wood to fill the airspace so as not to crush the aluminum when I bolted the outboard on. So I had two bolts through the outboard and height adapter mounting plate/transom described above, and two bolts through the outboard and transom below. It worked happily for many years in that fashion and never had an issue with it. The adapter was long enough overall that I also secured it with two more bolts near it's lower extreme.
Put another way; set the riser down over the top of the transom(if memory serves it extended 6" or so below the top of the transom), about an inch from the bottom of the riser I drilled two holes to insert 1/2" bolts with nuts and washers securing it to the transom, then set the outboard on, marked the mounting hole locations on the outboard bracket, pulled the outboard off, drilled the holes then installed the outboard and bolted it down.
Just be sure you have the correct height for the jet foot before you drill.BTW this was for a 55hp 2 stroke, factory spec. said it weighed 206lbs and it was on a 16ft Jon boat.
