So far I have just been lurking and finding out lots of good info. But, now I have a problem and I can't find the answer so here goes.<br /><br />I received a 1964 Johnson 9.5 from a friend for a price to be determined after I got it running properly. He said it was overheating. I thought no problem I'll just change the impeller and away we go. So I took the lower end off and sure enough there was rubber everywhere.<br /> <br />Only problem is that the driveshaft did not come down with the lower unit. I have since removed the powerhead and can see where the shaft goes into the engine and have been soaking it in WD-40 for a week and putting wood blocks on the bottom of the engine while holding the driveshaft and hitting the wood with a hammer all to no avail.<br /> <br />If I ever do get the driveshaft out, the lower part of it has quite a bit of scoring on it where it goes into the lower end should I still use it?<br /> <br />Any help would be appreciated.<br /> <br />Tx
