I hired a mechanic to provide an annual service on our 2015 Cutwater C30 with a D6 435HP engine. Because of space constraints, he said he could not access the impeller and had to remove the water pump. He then said he could not reinstall the belt single-handed and had to call for additional help. It took him six hours to replace the impeller. We are new to the boat, and this is our first service. Is this normal?
