The problem is not with the SeaStar units, they are the victims of the root problem You have stray current, this is attacking the cylinder shaft, which in turn is allowing fluid to leak out and water to get into the system. When the water/moisture enters the system it begins to attack the metal parts that are at the helm pump. Before you purchase a new helm pump, or cylinder. Suggest that you contact Fluid Tech @ 904-384-9659 and have them take a look at both of the units, depending on the damage, they may be able to repair them. BEFORE you install the repaired, or the new parts you will have to blow out the hoses with air pressure to ensure that no more of the water/fluid mixture is in there, then. You will need to ground the cylinder to the motor to prevent this in the future. We have ground straps for these cylinders and if you let me know your address I can send you one over there to use on the new parts thanks Marc I called fluid tech and the lady there called seastar and she called me back. I work at Gulfstream Aerospace and was on the phone with a customer and she left me the message that they told her the 4strokes put out more voltage and needs to be grounded. They now have a grounding strap, of which I have one on my new cylinder. Glad you guys know it all!
