You are missing part number 6 (305304) which sits on top of the water pump housing and connects to the exhaust housing. I had the same problem on my QD23. Without that part, water shoots up the drive shaft "canal" and out those holes. You’ll have to find a used one as they are unavailable. You’ll also need the two O-rings which fit on the top and bottom of the spacer.
