Good morning, you're going to needto remove the lower unit, water pump cover and impellers and blow everything out with compressed air and possible clean passages with stiff wire. I also suggest replacing the impellers as well. I'll post the exploded view and parts list below. IF I can help further just let me know. http://www.boats.net/parts/search/Yamaha/Outboard/2002/F4MSHA/REPAIR%20KIT%202/parts.html If my answer has helped you, please help me by leaving a rating or accepting my answer so I may be credited.
