I have a 1981 (I think)Evenrude 15 hp ourboard which has not been run (except for about an hour last year) for 10 to 15 or more years. I have been told that I should replace the water pump impeller before I use it much more. <br /><br />Question #1: is this necessary?<br /><br />Question #2: Can someone fax or email me an expoded picture of this vintage motor to help me with dis-assembly and re-assembly?<br /><br />Question #3: Any words of wisdom or "tricks" involved with this kind of maintanence? <br /> <br />Thanks. usccdet@comcast.net
