I have black 5 HP gamefisher as a back up for my larger boat. Need to check and may be change impeller. Lower unit bolts are off, lower init is free, moved down about 1/4". That's it, it does not come down anymore. Seems that either the shaft is stuck or the shifting bar needs to be disconnected. The shifting lever has no bolt or screw on the bottom to be removed. No access holes around the shaft. Sears pictures shows some shifting rod going up with a splice. (Not sure if it's the same model. THis bugger does rotate 360 deg. neutral, and gear shift on the side. I don't want to force it more then I already did. (I think I broke the shifting already) HELP !!!! Thx P
