Submerged outboards

Crane boom fell and sank buddies work boat three weeks ago. Third party just completed repair on crane and pulled boat out of water. Boat was north of I-10 calcasieu river so not sure about salinity levels but figure avg 5ppt. I am thinking the only parts salvageable are the lowers.
What say you?

Agree. Anything electrical will have gremlins forever.

Underwater for 3 weeks (salt or fresh) is FUBAR

Pretty good and fooked most likely
What kind of engine? An old mechanical 2 stroke would likely be salvagable. A new four stroke MIGHT be.
What's important is that as soon as it comes out the water, your start tearing it down and dealing with it. Sitting in the water is better than sitting out in the air after it's been submerged.

Twin Yamaha 150’s
I doubt even if you got on them quick it would be money well spent replacing just electrical.

Evinrude has procedures for dealing with submerged engines. Yamaha might have one?
But yet, electrical system will be a nightmare. Not to mention if they did get hauled up and are sitting in open air right now, bad shite is happening in there. They can likely be saved but money well spent it most likely won't be.

3 weeks is a long time.
I dont know. If he has insurance- file claim, total them. New motors.
If he doesnt have insurance- who knows. Could be worth a shot. Pull plugs, dump diesel in the cylinders, unhook all electrical connections, clean, apply anti corrosion of his choice, let it sit a few days to dry, repeat, then blow out cylinders and see what happens.
I mean- without insurance- worse case their is you spend some time trying to salvage them and no luck. Best case- they run.
I am interested in hearing the outcome. Quite a few of my buddies have submerged outboards over the years. Don't know if any ever stayed in that long.
Buddy has a merc 40 Tiller he submerged for about an hour(5 years ago) its still running fine today.

Port motor is running, stb motor was still being operated on when I was there. Hand hit both with gallons of wd 40 last night after the boat was back at shop. Owner doesn’t want to file claim since his insurance company will subrogate against the crane owner and they do business together. They’ll probably work out some kind of agreement to get him whole.
Skegs and props got fubared dragging boat out and on to barge, blocks look incredibly good for 3 weeks at 30’

I sank a Zuke 175 in brackish water x 24 hrs,,,,floated her up, towed her in, drained everything, washed her with 50 gallons of hot soapy water, unplugged every connection and cleaned that with diesel, filled her up to the top with diesel, drained that, wrapped her in plastic sheeting and ran a dehumidifier for a few days, sprayed all the connections with dielectric grease and reconnected, put fresh oil and filter, ran it for a minute or so, drained that, put fresh oil and a new filter, put her in the water and ran her at 5500 rpm up and down a freshwater river. That weekend I took her fishing and never had a problem for close to 10 years except the trim motor had to be changed. I put about 30-45 minutes on her every weekend going to the camp, and fishing a few times a month, so a lotta hours, finally started getting water in the oil and she seized up a few months after that. If you do it right, most jap motors can be saved to an extent.

Google “pickling” an outboard engine. Problem is you need to do it as soon as you pull it out of the water as the cylinders will begin to rust everything as soon as it’s exposed to air.
My ‘07 F250 went underwater in the 2016 flood, I pickled it and it’s still running today.

I'd let the crane holder's insurance handle the claim or the crane owner make restitution without involving his insurance company. I would not file it on my own insurance.

Nice. That may be good news. But yeah- won't rust until it is above the water.

My buddy owns the TowBoat franchise along the Texas coast, it's pretty crazy some of the engines he's saved by pickling them as soon as they come up. As you can imagine he buys them pretty cheap from the insurance companies.

Go to any port outside of the US or Europe, preferably one in a "shite" hole country. Ask who's the mechanic. Fly that person in and they will have it right as rain in about 8 hours. I had 2 boats in the Carribean for 5 years and outboards that we would use for anchors are hanging off many a commercial fisherman's boat and they keep them running for years without access to parts and think nothing of heading offshore in a boat with a motor on it most of us wouldn't take to the local pond.
I had a 70 HP OMC in Cuba once that had been submerged numerous times and the compression on it was so low you could just about crank it by spinning the flywheel by hand. That motor is still being used at GTMO. Folks without money are resourceful as hell....

Stb motor is also running now

I had one that went under in a flood and froze up, total loss.
I was told if I could have gotten oil in the cylinders before air got in, to cause rust, It maybe could have been salvaged.
