no way without frying both the simple electrical and any fancy electronics.(I assume it has none of those.)
had a clamped on outboard hop off a transom held on by wires and steering cables. got towed to shallow water but alas the main +(red) wired fried and broke. towed it home replaced the wire and it started right up ran it for a good long time to blow out any water in the engine....
took it out later that day and cruised all over with it.
but electrical will get you and no intake snorkel ever invented will prevent that...
I’ve been almost as deep (water over the hood) in a Land Rover Defender 200TDI.
Not by choice, mind you. We had a guy with a broken leg that had to get back to civilization.
I'm surprised you didn't damage the engine due to hydrolocking.
That Jeep in the middle of nowhere show that only lasted two episodes last year had a deep water crossing that was deeper than the engine.
The tech guy showed how it was done with some rubber, tape and some kind of silicon grease.
Basically cover every crack and its only good for a short crossing like in the clip.
That is probably an HJ (diesel) rather than an FJ (Petrol) Land Cruiser.
We had both a Diesel Isuzu Trooper and a Diesel Daihatsu 4x4 get sunk in various rivers in Western Kenya. Electrical systems worked just fine after we dried them out. Same for a little 800cc Suzuki jeep (petrol engine) that was in deep enough to be floated downstream a ways.
The old M-151 military jeeps had fording kits with snorkels, extended tailpipes and distributor seals. You had to disconnect the fan belt first, otherwise the fan blades would be pulled into the radiator by the more dense water, chewing up the radiator.
