I used hose from discounthydraulichose.com. The stainless fittings were really pricey, so I just went with steel and they have held up just fine. None of my hoses go outside of the boat though. The hoses to the rams are part of the imco kit that I used. I wrapped the hose with masking tape before cutting to keep them from fraying. The fittings to the helm were purchased locally.
