Hello

Need advice - our 2022 pontoon was hit in a storm at the local marina and was flipped upside down and submerged. Was under for 2 days in our local fresh water lake.

It has been sitting at the boat yard for 2 months waiting on the insurance company to do there thing. Got it back today.

Was thinking before I try to start it wanted to do some maintenance and some checks.

Here is what I was thinking but I am no boat mechanic so your input is appreciated.

2022 Mercury 90hp CT 4Stroke

Thoughts on the following:

Drain Fuel, Engine Oil, Lower Unit Oil

Pull spark plugs and inspect cylinders for water or damage.

Thank You for all input.

My factory service manual states,
“If engine has been dropped overboard and not recovered immediately, the engine must be serviced within three hours after recovery.
Once the outboard is exposed to air, both fresh and salt water will start etching the highly polished bearing surfaces of the crank-shaft, connecting rods, and bearings. The engine must be serviced within three hours of recover to avoid costly repairs. Proceed as follows”
