Boating today...
"Jim" wrote in message ... "Eisboch" wrote in message ... "HK" wrote in message . .. Who told me that? A "techie" guy on a real boating discussion board, who backed up what he said with a quote from the manual. Your "techie" is full of it. Hydraulic systems are capable of very fine and repeatable positioning due to the non-compressibility of the fluid. They are used often over cable or pneumatic systems when fine positioning control is required because they overcome the "sticky" nature of pneumatics and the stretching of cables. In the business I was in we used air over oil hydraulic systems to precisely move and locate 500 lb objects to within thousands of an inch. If the hydraulic steering system has not been purged of all air, or if there is a leak, I can accept the helm position non-repeatability. But, if leak-free and purged of all air, it should be perfectly repeatable. It's the cross wind. Eisboch To be sure, if you see Krause's name anywhere in a thread, you will be seeing a lot of horse **** being thrown around. Cross wind will cause you to have to adjust helm position to maintain a straight course but I don't think that is the complaint. the issue is that when the boat is at rest and the engine is centered, the wheel position has changed from it's original position. I just took a peek at the Sea Star Web site. It seems there check valves and pressure relief valves built into the system. A leak in a check valve or operation of a pressure relief valve could be the cause of what these guys are seeing. No? Not to mention seal leakage. I don't think these are precision devices like the ones Eisboch is used to dealing with. The subject has been beat to death and if anyone doesn't like the fact that the suicide knob wont stay at 11 O' Clock, they should contact Teleflex for relief. Or they could have Eisboch's old company design and build a precision $500,000 helm. Sorry, banana breath, but there's no good reason for a new hydraulic steering system to leak or suck in air. check valves or not. Cost is not an issue. Eisboch |

The nice thing is that it's easily corrected - add an ounce or two of fluid and your off and running for another couple of years. The helm "pump" actually acts more like a worm gear than a pump and there will be slippage there also over time. Mine is bled and purged every year and so far, it's been very reliable. ~~ knocks on wood ~~ I'll be glad to sell you my knob at a discount! Excuse me? |

So internal slippage/leakage, etc., cannot happen if no air is in the system? |
