Perhaps I mounted it too deep, but I seem to remember I did it according to their instructions.
I took a straight edge and held it flush against the bottom and drew a line on the side of the water pick up, and cut off the angled part so the outside part was ⅛" below the line I drew. It still had tremendous water flow, and had to be a marked improvement in drag reduction.
Remember that I had a Volvo drive, which does not contain a water pump like the Mercruisers do, so I already had a crank driven water pump.
What started this process was that I wanted a smoother drive, so I filled in the water pickups on the front of the Volvo 290, which had been the water source for the engine. With that source gone, I needed a new one, so I purchased the transom water pickup George pictured.
