Black smoke on the transom could be normal and you can simply clean it off with soap and water. Black smoke means unburned diesel fuel is exiting the exhaust. Diesel engines normally project black smoke when first started or heavily loaded and their rings haven't warmed up enough to seat properly. Could mean the rings or cylinders are worn. Something you could try is to change your oil and add some SeaFoam to it when you add the new oil. It helps with lubrication and helps the rings do their job. If that doesn't improve the smoke, change it again and add the Seafoam to both lube oil and the diesel fuel tank.
How's the engine temperature? It's important to keep it within manfacturer's min and max.
