Re: '83 Johnson 15hp - Drive shaft stuck in Power head
HI Kenbe11, Your best option is to remove the powerhead and turn it upside down. Apply a good penetrating oil to the driveshaft where it goes into the crankshaft. You will probably have to let it soak a few days. I put visegrips on the driveshaft in a location not to damage the waterpump or bushing areas and tapped on it with a hammer, don't tap too hard you could bend the shaft. Sometimes I have heated the driveshaft and let it cool a few times and that helped. In the worse case, I have cut the drivesheft and drilled thru the center of it and tapped the hole and used a puller to remove the piece of the shaft and install a new driveshaft. Hope this helps.
