Hello. my mariner went for a swim in the ocean. i recoverd it and did some first aid on the engine.
clean with freshwater. flushed the fuel system and flushed the 3 carburetors.

it wont run at idle. and i need to find the rpm sweet spot to make it run in neutral.
i got it to run today for 30 minutes. it runs a little rough.
i cleaned the spark plugs and before i got the engine to run for 30min. you can se the before and after result in the picture.
could anyone help me. it seems that one of the cylinder get to little or the two others get to much.

Left spark plug is cylinder nr 3 Bottom one.
Middle is Cylinder nr 2 middle one.
and the right is cylinder nr 1 the top one.
