Got a question about the new (2017 and after models) blades, I’m mounting a pair of 10’ blades and in the diagram it shows to leave a loop of the hose when it comes off the poles and before it enters or goes through the transom. Wondering if this much slack is necessary? I don’t remember seeing it like that on any other boats that have the new ones. I’ve raised and lowered them and it doesn’t seem they are using that much slack. Has anyone mounted them or does anyone have the new 10’ blades on their boat that could look and tell me?
