I have a 24' cc with hydraulic steering (single outboard). I have had to bleed the system at the wheel every year and sometimes more. A repairman stated that there was alot of rust/corrosion around the helm end. He also said that a complete new system would be $1,400, which he thought would be better to do than just a new helm due to the age of the boat (1995). My question is, can you replace the helm only if that is where the leak is and feel good about the other 16 year old parts? By the way I just spent a fortune putting a new motor on it so I'd like everything to work right but not sure if I need to re-do the whole system. The repairman did not state that he was 100% positive the leak was only at the helm.
