I have a 1983 alpha one outdrive. I did a impeller job on it and belivie i put the housing back on wrong. first i did not put it in drive is that the fist mistake? When i went to put it back on it did not want to go on right so i held the lower unit while my friend taped the key to get the gears to line up. Number 2 that was wrong to? Then i got it all put back together and started it up went to go put it in drive and the shifter was stiff and hard to put it in to drive when i did get it in drive it died. Do i have the gears in a bind or what did i do? Thanks Snyman
