Hi all, I found this site yesterday and can honestly say it looks to be the best site I've ever found on the 'net! (ok, well Ebay is good too)<br /><br />I just acquired a 1983 15hp Johnson and want to do some things to it, replace the impeller, etc, just give it a once over. It seems the OEM manuals for this motor are hard to come by. I found a 1984 OEM manual- are there any differences between the years, or would I be safe getting the 1984 manual for the 1983 motor?<br /><br />thanks!
