Bruce, I think the usual installation is located in the cockpit area such that one may continue to steer the boat (near the normal helmsman's position) - in the vertical side of the seat base with clearance for the handle taken into consideration. I do not have one mounted in my 17 as of yet, (planned), but have had them in previous owned boats and most OEM installs I recall were along those lines. Maybe a quick check of Mate's fine works would elaborate/correct my viewpoint. Can't think which side of the cockpit is appropriate ('Tryin' to think and nothin' happens') I have used a pump mounted to a board (6''x24") with hoses but that was for moving from boat to boat and 'service duty' type work around the marina.
