For my ignorance, I ordered a repair manual before finding out the exact model year of my Johnson. Here is the question:<br /><br />Mine is RK-24L ('62 40HP) and my manual is 1302 which covers 1971-1989 Johnshon Outboard 2Cyl. While waiting for the correct manual to come, I am wondering if there is significant different in the engine design regarding to impeller replacement. <br /><br />Is there anything I have to watch out while doing this? it's gonna be my fist major work on a marine engine even though I thought I am very mechanic-inclined.<br /><br />BTW, is there anyone who's in need of the above repair manual? give me an offer.<br /><br />Thanks,<br /><br />Nam
