But again, take note to the things I mentioned in post #9. I'm, by no means, telling you here in the post that it will be a breeze. It's going to be more of an emergency thing. Tight quarters? It'll be hairy.
Thinking of adding outboard

- outboard add?
Drain 'em out, fill 'em up, check the cylinders, squirt 'em down, check the fuel and see what happens.

No chance. There would be no chance of maneuvering it, not to mention the slightest wind or current and your done.
As mentioned, if you remove the engines and running gear. Sealed the shaft logs properly and mounted dual 300's with an Armstrong mount, you might have a chance. Even dual 225hp you could "motor around" although not suggested. But with a single 25hp that can barley get a boston whaler on plane, you have no chance of maneuvering.
No really. New/rebuit long blocks are the answer there.

Put some sails on it! Only kidding...only kidding.
Another idea - use your 340 as a condo at the slip (immobile) and buy yourself an inflatable to scoot around the canals and bays on. Dinghies are some of the best boats money can buy...

If the engines were flooded with rain water. I would bet any wood in the boat such as stringers, transom are rotted as well. Check that before anything.

I don’t believe rainwater could flood an engine the way they are setup. More likely the boat partially sank which may explain why everything in the bilge looks off.
Boats are a money pit. Either fix it or sell it. Putting an outboard on just doesn’t make financial or operating sense.

Right, you mean sunk. Or the equivalent.

Not likely unless he lives in a Monsoon zone. 40" of water or so should do it......taking with it the engines, drives and stringers. You can't get rainwater into an engine without laying waste the rest of the boat. This is a Sedan Bridge not a run about.

I don’t understand how this would ever work. Repower or cut your losses. 30 HP will barely move this behemoth. Like I said minimum 90 HP to beat any current or wind to make it a barge. To mount and be able to control an outboard will cost more than a new long block. A new long block installation will very likely uncover more issues and hidden decay.
Why did you buy this? I hope it was less than $2,000 total.

I would never take friends and family out on open water (or creek canal) without both engines running properly, and a 20-30 hp kicker will never allow to safely maneuver that boat.
What do you have in this, and how much are you willing to spend? That will dictate best options.
350 long block with you turning all the wrenches is likely $5k.
Add up what else needs to be done and see if your still in. Boat in good running order is might be worth $15k, maybe more, maybe less depending on other factors. I assume the generator doesn't work either? If not, that a big issue too.
Unfortunately, you bought a money pit.

Something not mentioned as far as the kicker goes, is that you will not have any reverse thrust. If the prop does not reach below the bottom of the hull, there will pretty much be nothing there.
Fixing the failed engine is the way to go.

Unsure what year/model your engines are, but, as an example, this 8.1 big block can be had for $7499 times 2 plus shipping https://www.michiganmotorz.com/8-1l-vortec-marine-engine-375-hp-2001-current
However, as others have pointed out, by the looks of the engines and genny, there's a very good chance you have more problems than just the engines. How handy are you with wrenches and major fiberglass repair work?

We also have a 4,200 (Empty 3,400 pounds) pound 21 foot jetboat with a 9.9. This past summer we had problems with the main engine. We went 20 miles up river with the 9.9. We went about 2 to 3 MPH and burn as much fuel as the main engine would for the same distance. On flat water the speed is about 7MPH. Maneuverability is very difficult I assume due to lack of power. Last fall we saw a Cruise A Home boat with twin outboards. Owner like it but said it was difficult to maneuver in tight areas. Boat originally had twin stern drives.

Thank you for the comment, i am also concerned about maneuravility since my slip is at the very end of a tight canal.

Thank you for the comment, i am not experienced with wrenches/fiberglass...
Any ideas on what that work would reasonably cost?
Also any ideas on replacing the genny? Solar?

Thank you for the comment.
I would need to be able to reverse, slip on tight canal round a corner...

One of the engines seems ok, needs starter, other has water.
Any ideas on how much would the work to replacing the engines cost?
Any alternatives to replace generator?
minimum of 5K for the engine and probably another 2k-3k to install. If they find stringer rot during swap, add another 10 - 15k. It adds up quick. Buying a used boat with a flooded engine, is by-definition a money pit.
If it were me I'd sell, or give away the object formerly known as a boat, and consider the money spent as tuition.
