Hello all. I have a Seastar hydraulic helm that I need to replace. When I disconnect the hydraulic lines at the helm, will I need to first purge out the hydraulic fluid, or can the lines be removed without a lot of spillage? I know I will have to refill and purge the system after install, but I was hoping to be able to disconnect the lines without completely draining the system. All I need to do here is swap out the helm pump for a new one - same make and model. I am hoping this will be a quick and easy swap out. Thank you in advance for any insight you may be able to give!
