I have a 1998 mercury 200 EFI and yesterday when i was flushing the motor i noticed it was not peeing as strong. I am unsure the last time the water pump was changed so i would like to do that. My question is i am unsure which parts i need, i was looking at the iboats parts and it has a complete water pump housing kit and just the impeller kit. Which one should i get? Thank you for your help
