Im changing the impeller on my 79' johnson seahorse 4 h.p.<br />there are two sections of 4 bolts holding the lower unit on. I took the lowest set of 4 bolts off and thought I would just pull this off? nope. So, I unbolted the next set of 4 bolts and I cant get this lower unit to budge? can I bang on it with a rubber mallet or pry? there cant be anything else holding this in?<br /><br /> #'s on motor: 4w79d<br />Thanks for any help,<br />Suzuki40
