View Full Version : Reinstall lower unit on Force 120

I just finished changing out the impeller on my 1998 Force 120 and can't seem to get the lower unit back on. It stops about an inch from seating up against the upper unit. Any thoughts?

Did you rotate the flywheel very slowly by hand to allow the splines on top of the driveshaft to mate and seat properly with the crankshaft?
