Review on Sierra 18 3147 Water Pump Kit by Joshua Flake

Everything you need to replace your Mercruiser Gen II outdrive water pump. Every part was well made with the exception of the pump housing outlet which was not properly formed making it a bit difficult to connect the upper and lower units. Made it on the third try. I found that having a stand to hold the bottom block upright and then dropping the top block straight down finally worked. The pump will now properly pump water through the engine cooling system.
