From inside the boat open the engine hatch, and right side, rear, lower, of engine (in the bilge area) you will find your belt driven lake water pump. The spin on water/fuel separator is beside that water pump. $20 at West Marine to $12 on Amazon.
For an 09 Enzo, throw the wake shaper in the garage and leave it there. Lean the boat to the rub rail on the surf side. Use enough counter weight (non-surf side) to keep the rear of the boat just in the water. Use the plate to clean the wave. Start with it all the way up, and then bring it down in small steps until the wave is clean. The speed should be between 11.2 and 11.6.
