A SeaStar II helm pump (2.4 displacement) is recommended for a twin engine installation, with twin cylinders. I use such a system on my Outrage 25 with twin 200 EFI Mercs. Unless you want very fast steering, with more effort, I would not use it with a single cylinder.

It could be that the whole hydraulic system was after-market fitted to your boat by someone who didn't know what they were doing. For a single system, you want the Sea Star I helm (1.7) or maybe the 2.0 pump. Check the Teleflex website for pump vs cylinder recomendations.
