How to Remove Water Pump Yamaha 115hp (115TLR)


How do I remove the water pump and reinstall it on my Yamaha 115 hp engine? Is there literature from the manufacturer that gives correct step-by-step removal and installation procedures? There must be assembly diagrams somewhere, but where?

My 2008 engine model is 115TLR. Any help would be appreciated. Thanks.
