I bought a used 2004 Nitro Sport 188 a couple of months ago. It has a Merc 125 ELPTO motor. The steering is extremely stiff and I have noticed that the steering rods at the motor have dried grease on them and it appears that there is little to no grease in the tubes. I am not certain of the names of the parts, so bear with me. The steering has dual tubes right in front of the motor with the steering rods that come out of them to attach to the motor. I have a service manual for the motor from Merc, and it shows grease zerks on the steering rods where you lubricate the rods and sleeves. My steering does not have the grease zerks, just big nuts that attach the cable to the rods and sleeves. Without the zerks, how do you lubricate the rods? Just loosen the cable nut, pull it back and squirt in grease?<br /><br />Any advice would be appreciated.<br /><br />Thanks,<br />Paul
