The "service" when they go into salt water is bascally to flush it with
fresh
water and get it running.

You have one hour MAXIMUM after your pull your engine from the salt chuck.
Then you dump the powerhead in a tank of diesel. And if you cannot get it in
for service right away, it's best to leave it in the water for just a short
time. Or even in a tank of fresh water in the shop for a short time, if you
have no diesel available. If you leave it exposed in the air, your bearings
will begin to rust. And that will cost you a lot of cash.

Any engine that has been in the salt water must be dismantled and cleaned to
remove all the salt. You cannot just flush them and get them running, that
is "back yard mechanic" nonsense. Any salt left in the area of the bearings
could shorten the life of, or ruin, the powerhead. And while you have that
engine apart, you put in a fresh powerhead gasket set (of course), rebuild
the carbs and clean out the rest of the fuel system and electrical system.
If you don't do the above, you are in for "****" next time you hit the
water.

Basically, any complete salt water emersion calls for a rebuild.
