I just purchase a 07 VIP boat with 16 hours on the MerCruiser 3.0 Liter engine, I am having a problem with the power steering the boat is very hard to steer and feels like there is no power steering. I have checked the fluid level and the belt is tight on the power steering pump. I would find it hard to believe that the power steering pump or actuator is bad on a boat with 16 hours on it. Is there a steering cable I can check, If it was the pump or the actuator how could you tell which one was defective? Thanks for your help
