I had the same problem with a 87 mariner,, it was hell lining that thing up, but once you get the lower unit stabbed. your good to go.
Many living in this generation shall never see the grave, JESUS gave us revelations and the time is very near. Dont be a soul that stands before GOD on judgment day and be told "depart from me, I do not know you".
REPENT, RECIEVE, REJOICE!!!
