i need to changet the impeller on my merc 110 9.8hp and when i got the lower unit apart the impeller fins are going to different derections so i dont know which way it is supposed to go....i attached a picture and wondering if u anyone could tell me by looking at the picture which way it should go.....by example A or B by looking straight down on the lower unit from the top... also do i really need to install the whole waterpump kit or just the impeller....everything looks really good except the impeller which looks fried
