Was it running or not??? Also any advice now would be a bit late unless it's just happened!!!

Drain sump - flush through with oil. Change filter of course. Remove all sparkplugs - squirt oil into holes - crank over several times - by hand if possible.

Also flush cooling system right through - alternator will also need to be washed out in freshwater before spraying liberally with WD40.

When engine running ok - do another oil change to be safe.

Of course distributor will also have to be checked - and coil - long list really!!!

Just remember to flush everything with freshwater to get the salt off - ideally straight after it was swamped!!!

All the engine needs to be flushed & cleaned not just the inside of it, washing with fresh water will not remove all the salt or stop corrosion. All the electronics will need sorting as will the carburetor. I race zapcats and have turned my boat over, as soon as we get it home I stripped of the electronics and put it in salt-x overnight and then dry in the rad at home i also filled the engine with salt-x. I then put it all together With clean fluids and run it that was over a year ago and it still runs well.
I’m not saying salt-x will stop the electronic breaking down in the future but it will help them last longer.
There is some salt-x on ebay for sale at the moment.

if it happened in saltwater and its been left for more than a few hours it will need a complete strip and rebuild,it will already have started to rust the crank and bores.

Remove engine from boat.
Flush out three times with diesel. Remove spark plugs from engine for flush out and turn engine repeatedly whilst ful of diesel.

Remove altenator, Starter motor, starter solenoid, auto choke and place gently in refuse bin. Purchase replacements. Fit replacements.

Purchase isolator switch for battery.

Replace all electronics in boat.

Easy.

Thanks for all the help.
