Re: 9.9 evinrude motor
First, it sounds like from your post that you are new to outboards. A Manual would be in order. That will walk you through many problems. As for the cooling problem, it sounds like your water pump needs replacing or the water passages are clogged up. The flywheel has nothing to do with water output. Can you give us some backround info on this engine? Did it pump water at anytime before? Is this engine new to you? Model number would be good. Has this engine been run in saltwater? Any other info you can tell us will help to solve your problem...<br /><br />PS: Do not run that motor again until you find the problem. Could be very bad....
