He repowered with a single pod mounted Yamaha 60 outboard, which worked well, if a bit thirsty. That motor was removed (with a chainsaw) during the salvage process.

Currently the boat has no motor, but IMO it's quite telling that even though it still has the diesel genset and the lithium battery bank, the owner is not even slightly tempted to try electric drives again. I'll be doing a dual outboard installation similar to my own.

No surprise after those issues! I have just the opposite assessment after many gasoline outboard problems, one story I relayed on here where mine wouldn't start back up again and my boat whacked into a barge.
I replaced it with an electric outboard I built myself.
I also hate the smell of diesel, can't really understand how anyone puts up with it, particularly on a sailboat.

The torqueedo's seemed very small for a boat that size. I gather there are not many other available options.

Double Exposure was built to be a powercat with an aux. sail. Powered by Evinrude 115's. She can do 20 knots. Under sail power alone, she does 5-7kts. The 2' draft is a huge bonus.

Current thinking is Tohatsu 30's. A bit heavier (only about 15kg each though) than the Hondas, and have 3 cylinders and fuel injection, so should be smooth and economical.

The main challenge with the installation will be where the helm positions are on the boat. It will mean having the motors a bit further aft than would be ideal.
