The boat has a full helm "Hynautics" steering system that is ran off a pressure tank. Steering is nothing short of a chore. Is the solution as simple as adding pumps and retro-fit? or would I be better off starting from scratch?

Not possible, the Hynautic is a manual pump, the tank is just an oil resevoir. It is pressurized so it can be mounted remotely below the helm.

there are ystems out therer that use an electric hydraulic pump instead of the air assist. these unita are similiar tot the new merc style systems on the verado's . hynautic, sea star, teleflex, and i believe latham have them.

good luck
