I'm putting my boat in today and was trying to finish off the lube process on all the systems. According to my manual, I'm supposed to grease the power actuator valve on the power steering ram assembly. I looked for a zirc fitting but can't find it. Is there a zirc fitting for a grease gun or am I supposed to take something apart and grease by hand? My clymers manual wasnt clear on this. Any OMC mechs that can help? On a related note, I have some play in the steering, its not at the helm or in the cable, what would the likely culprit be?
