Gaskets need to be genuine-some are heat resistant.
Serial number has no direct bearing on age apart from it being identifiable from a chart.

when i say completly flooded it wasnt full of water but enough to cut her out
Pistons seem to look ok rings seem to be ok and the crown of the piston although a bit coked not too bad (from what i can see through the four holes ( two for each piston)
Its not seized in any way and plugs are in good condition (not just replacements)

From your posts and your own admission, you don't know enough to fix it and you're making incorrect assumptions that sound like you really need to understand the motor better before attempting to fix it.You need to buy a manual and run through it step by step or bin it.It's certainly not worth getting a mechanic to fix it as the bill will be higher than the value of the motor.
Try replacing the cover plate gasket by all means, but I really wouldn't be happy using that engine without knowing it's sound and you need to learn more about them before making that judgement.

4 stokes not a problem but two strokes are a different kettle of fish. its not a case of not having the ability to fix it more of where the parts are and the terminolgy used to describe the areas ( if you get my meaning) to me an engine is like any other piece of machinery man built it man can fix it its only nuts and bolts (assembled in the right order

I wouldnt be taking it out far its mainlyt for use in training my newfoundland puppy for water recue work ( LOL so if it does break I can always get the dog to tow me back )

Fair, but it's not just a 2 stroke,it's an outboard as well so normal rules for modern (ie normal land based) 2 stroke engines etc don't apply due to the cooling,fuelling,ignition and exhaust systems as diagnostics aren't quite the same.
No insult intended but you do need specific knowledge of what's what and where it is-hence the 'get a manual' comment.

400 yards out is too far if you've got no power and being blown offshore faster than you can paddle or the dog can tow you-unless you're thinking of lake/river use only.

fair no i didnt take offence at the manual bit its just that before i shell out 45 notes on a manual i was wondering if any one had any ideas or had come across it before.
Have tested the piss pipe and it leaks through the exaust gasket so thats my first port of call is to change that then we can go from there

cheers allen

on the port side of the p/h there is a plate that is the exhaust cover where water can leakinto a cyl.The obm serial number on an old obm like that, look for an aluminium what looks like a core plug the number stamped on that is your serial number (if it is still there) as a team tip no serial number it can be hit or miss about getting the correct spare part as there could be a serial number break for parts

KKKKKKKK YEEEEEEEEEEEESSSSSSSSS
exaust gasket changed (both inner and outer) ran it on a HEAVY oil load to be on the safish side and it ran
Mix some decent fuel tommorrow and put a new pull cord on then leave it in the weely bin for a couple of hours running it in and see how it goes

Cheers to all that have helped so far
Allen
