My outboard decided to make a bid for freedom last week and jumped off the jetty, unable to launch an immediate salvage operation at the time i'm wondering if 1week submerged is too long.

The real problems start when the air gets to it , so you should be ok ish.
man recommennd re immersion in fresh water at the start of the recovery process.
go for it,

If, by any chance it's a Seagull, then you'll be OK for a good few weeks yet. So long as you don't tell anyone on this board.
If it's not then an immediate very thorough rinsing of the whole motor in fresh water is essential.

I think david bagshaw has the right idea. If it is a two stroke..
Don't hang about when you get the thing out of the water. A small engine can be inverted in a tank of fresh water and then washed with a pressure hose (drain the fuel first). Give it a long blast all over inc down the plug ole. When you are sure all traces of salt are gone, dry it off as best you can and put oil into the cylinder and turn it over lots. Dry it with a hair dryer and give it a dose of WD40. Clean or change the plug, and check for spark.
Put clean fuel in and start and run as soon as possible. The less time spent idle in the fresh air, the better.
I had one that was under water for six hours and I kept it for over 10yrs, it ran fine afterwards. Let us know how you get on, a week could be a record.

A week wouldnt be a record,what about restored planes from the war etc.
The fact it wasnt running will be in your favor.
remove, rinse, loads of oildown air inlet in carb, lots of pullingover with plug removed.
It is all aboutkeeping the wearing surfaces well oiled, while sorting out the carb and electrics

Don't forget to get into the magneto and flush out the coils, then liberal use of WD40 to get all the water out. Ther are many stories of recovered outboards working fine for a few months and then the coils have rotted out.

I reckon a week is too long...have known engines - Mariner 2 & 5hp 2-strokes - knackered after 1 tide, certainly requiring new big ends.
As soon as the engine is recovered, get the plug out and hose the thing down like mad, filling the combustion chamber with fresh water & turning it over with the chord; if it's not already seized.
Remember of course WD40 stands for Water Dispersal...

I have succeeded with an outboard that was in the sea for a week.
It gave many hours of service over the next 4 years and got sold with the boat IIRC.
I think it's pot luck whether corrosion in the bore and bearings is excessive.
Rinsing any electronics thoroughly is important, then de-water with WD40 or similar.
Get it running ASAP.
Then let it run to get hot enough to dry out any internal water.
You will need to strip the carb at least partly.
Probably change the leg oil too.

Well its out stripped and washed, plenty of oil through spark plug and turns by hand. will try starting Monday. It was about 4 m down even at low tide today

NOOOO. Let it dry out, especially the electrics - just use more WD 40 in every hole and opening and gap you can find, then some more, then leave it somewhere warm and aired for at least a week, then try to start it.
Have you stripped the carb?

seagull dunking
I once found a seagull outboard in Emsworth at a very low tide. I took it too the sailing school where I worked and stripped it and got it running in less than an hour. When the owner finally claimed it, just before the 3 month limit that the police say was the time for claiming it back, he said he had dropped it 6 months before so it was in the water for 3 months!! It ran perfectly after a carb clean new fuel and spray with some WD40.

Well, 1 week submerged, 1 week in the garage being fed oil and wd40 and she has started fine.
Thanks for all the suggestions

Glad it all seems to have worked for you. We used to have an ancient 1.2hp Colt, which had a habit of unscrewing itself from the transom (single clamp) and going for a swim. Ten years on it's still going fine on a friend's river boat.
