it should be fine take the plugs out and keep turning it over it probly has water in t last summer some kid at my trailer park pulled the plugs out of 2 boats and noone noticed till the next morning we pulled their plugs turned them over till it stopped spraying water strayed a little WD in the ports while the plugs were still out turned it over a few more times then put the plugs back in and after turning them over a few more times they both started ran rough for a bit but still running good now

Drain the carb. and give it fresh gas. Make sure your plugs are dry as well as the cylinders and fire it up as soon as you possibly can. It is urgent to get it going and let it re-lube itself as well as dry out. Time is of the essence. If it sits water will go to work and start to rust parts quickly. Here is a link that will help.. Best of luck. Rick.

Not sure what year it is and if it has points. Pull the flywheel and make sure all is dry under it. Rick.

Fresh water or salt water?

It was fresh water and also it is a 1973 20hp johnson.

So your electrical system may have gotten wet, the engine will run on one cylinder and the heat from running will help dry things out.
The important thing is to get it running
