I am going to replace the impeller on my 2002 90HP Merc this afternoon. Besides the Impeller and the 2 gaskets what other supplies do I need.<br /><br />Do I need gasket sealer or anything like that.<br /><br />I do have the manual, but it is at home, and I would like to get any else I need before going home today.<br /><br />I have any tools that I would need, and I have done this before but I do not remember what I needed.<br /><br />Thanks for any advice.
