Eh? It's a sealed resin filled box so you can't go in & reprogram it!

so, although damage control is the best way to go, basically the right thing to do would be get shot of it quick after?

I was talking about this to a friend last night and I was trying to recall an article I read recently where some magic oil had been used to get a couple of submerged and knackered outboards going. Can't find it anywhere now but sure it was in a boating magazine. Does anybody else read it or did I dream it?

We saved an inboard diesel that had been under for a tide (not running when it went in) we hosed it all out with fresh water and then drained and flushed the sump out with diesel a couple of times then filled with new engine oil and a fresh filter,also took the heater plugs out and cranked the seawater out etc,then doused it all in wd40, once it had been running we changed the oil and filter etc again,twice. That was two seasons ago and its still ok.
BUT all the electrics were knackered and had to be replaced including the wiring loom,the alternator was virtually corroding away in front of our eyes.I think the batteries were still connected when it went under.
It wasn't in sand mind you, if it had been I was told it would need a complete strip down and rebuild.

Bang Goes the Theory

It's not this 60 Mercury that you're interested in, is it?

interesting idea - I think they made it out of a frozen pile of woolly mammoth droppings by the colour of it!

If you mean without being clear to the buyer on the history, that depends how you live your life. Not exactly pleasant flogging a screwed engine on to some poor unsuspecting buyer. Best not subscribe to karma.

Though i do know of one person on here who bragged about selling one on quickly after a salty soaking in the past. Suffice to say I have never recommended the business/person.

Personally, fix it up, sell it on, but let the buyer know. Sleep easy from then on.

you misunderstand, my question was in theory, in case it happened etc etc. my engine is thankfully fine, and not been 'under' just thought it good to know what to do if the worst ever happened!
i hope it never happens, great to hear all the advice though. thanks
