I have a 9780s weber 4 bbl on my1996 Chaparral 4.3LX Mercrusier. A 9600 Weber 4bbl should be on that engine. Will the bigger 9780s do any harm to the 4.3 LX? The 9780s came off of a V8 5.7

It won't hurt it, but the engine will not be performing the way is should. The carb is too big, and at low speeds, the air velocity through the venturis is too slow to pick up the fuel correctly. You may end up with rough idling, and poor acceleration... (as well as a larger fuel bill)...
