I recently acquired a 4hp Acadia that spent many years outside poorly covered. Am trying to resurrect her. There are 2 fairly small cracks in the water jacket. Can anyone direct me to a top notch welder who can furnace weld the cracks or possibly explain any better solutions. Also I would love to hear from anyone with any parts for sale. I need an exhaust manifold or a foundry to have a new one made.

The more important issue is:
Was the engine cooled directly with salt water?
There are numerous discussions about the effects of slat water cooling and the after effects when the cast iron dries out leaving behind the salt. Cast iron does have porosity and does absorb water over time.
There are numerous discussions about salt water engines - but most of them indicate that once the engine starts to crack, it's really difficult to stop the process.
Nevertheless there are also posts - especially one relating to a Barker engine that was rebuilt after very bad damage to the cylinder .
Now, if your engine is fresh water cooled, then, it's a whole different game.
I suggest that you look at the Barker engine discussion as a starting point.
Cast iron is not easy to weld and if it is only the water jacket, you may not need to weld it.
Also, have a look at Muggy Weld -
You might be able to find a local wewlder who'll give it a try.
