Evinrude lightwin 3602E (folding lower unit) drive shaft removal

[Meppsman]

1. Hello all,

I’m working on a 1965 Evinrude lightwin 3602E (folding lower unit). I’m trying to remove the lower unit from the power head. I took the 4 bolts off that fasten the lower unit to the bottom of the power head. I can’t seem to remove the lower unit. The upper drive shaft won’t seem to come out of the power head. Is there something else holding the drive shaft in place? I looked on a lower unit diagram from marineengine.com and it seems that there are 2 “roll pins” on the shaft? I’m unfamiliar with this part. Is this what’s preventing me from removing the shaft? I also tried to remove the main pin  at the bottom of the shaft (the pin that mates with the coupler on the lower folding portion of the lower unit). This pin is #50 on marineengine.com lower unit diagram. Sorry, I can’t seem to upload the diagram to this forum! But, I couldn’t get that to budge either. Are these removable? If so, is there a good way off getting it out? I couldn’t get a good angle with a punch. Any help is greatly appreciated.

Thank you,

Todd

Most likely the driveshaft splines are froze in the powerhead
crankshaft, but perhaps someone else will have other ideas.

Well, the lower gearcase should come off with its stubby driveshaft.  It is possible that the upper driveshaft is stuck in the crankshaft but this won’t prevent the gearcase from coming down…  The only other thing kind of holding things together is the water tube gromment, but that shouldn’t present that much resistance.

Feel free to post pictures, I don’t want to mislead you

I was thinking Todd was only worried about dropping the upper
housing, seeing that the gearcase is on a “folder”……. not
sure what pins he’s referring to though.
