Re: Mercruiser steering shudder
look at your power steering ram, on the narrow section there is a machined slot , this should be staight up and down. if this is correct start the engine and get someone to steer while you observe what is going on. if the ram shudders it is likely at fault, you should notice the shuttle moving smoothly in and out as direction changes. if there is any corrosion in this area that is bad(the shuttle is the larger 2 peice section where the pivot bolts to the t plate). also check your oil level, cold and warm. full lock is not something most rams like to do, kind of like the squeel you hear in your car at full lock. if all of the above checks out its likely ok. also check your power steering belt isnt loose.
