Hi,Iam very new to this and very new to boating,just brought a boat and haven't had it out yet.Someone suggested we change the impeller to start with,because the motor haden't been started for two years.So with that in mind we started,trying to drop the lower unit,YEAH RIGHT.So i checked out this bulletin board for some tips,read some good advise,after a few tries of getting it of,like probably thirty we done it,we used some wd40 and a bit of strengh and lots of patience plus a few tools to wedge between the gaps,popped of safely.The problem was it hadne't been greased last time someone had it off,so it was stuck.Anyway i dare say we will be using this board in the NEAR future,very near so chat to you again soon.<br /> A VERY BIG THANK YOU to all
