    Forward instantly shifts to reverse??? No neutral

    So after inspecting a diagram of this gear unit I found that there is supposed to be a spring behind the cam follower which I did not see as this came apart. After looking up parts I found it's called the cam follower compression spring. Looks like no one sells them either. I had a guy on...

    Forward instantly shifts to reverse??? No neutral

    So I got my 1984 mercury 4.5 lower unit put back together. As I assembled it I made sure I was able to twist the shift shaft and see that the prop shaft would go into forward, neutral and reverse. However, as soon as I got to installing the spanner nut until it bottomed out and lightly snugged...

    1984 Mercury 4.5. Pinion gear help

    I was able to get that screw out!! Yes!!! After pulling out the pinion gear and the back gear I was able to see that the drain plug shaft was too long and preventing the shift mechanism to move. Very angry I gutted this for nothing. At least I can clean everything really well now. I'm unsure...

    1984 Mercury 4.5. Pinion gear help

    This little guy is stuck in forward gear and sometimes I can get it into neutral but never reverse. I got the gear case taken apart down to the pinion gear but the pinion nut or bolt has a washer that looks like they used a punch to bend the washer so you can't take it out again. How the heck do...

    Finding the right tool for gear case 1984 4.5

    I have a 1984 mercury 4.5 and something is binding in the rear case to where it's stuck in forward. Trying to find the 4 pin tool for the lock nut but I can't find the right size anywhere. I'm measuring the ID of the gear case tube at 55mm. Any link would be appreciated.

    Need help to start 1984 4.5hp

    So another update. I was able to play with the shift shaft and vice grips. I could spin the crank shaft by hand clock wise and see it turn the propeller. I was able to slightly twist the shift shaft enough to where it was in neautral and the propeller would no longer spin while turning the...

    Need help to start 1984 4.5hp

    I didn't bother shifting it before removing the bottom. First thing I ever did to it was inspect the impeller and found it in pieces and replaced that. Then put the bottom back on, checked for spark, put in new spark plug, then changed the gear oil. The old stuff was dark. Then started it up...

    Need help to start 1984 4.5hp

    The gear case. I managed to get the carb off. I took pics along the way getting that choke assembly figured out. I looked inside at the reeds and was pleased to not see any rust and they appear to be in tact.

    Need help to start 1984 4.5hp

    That's great advice thank you for that. It looks like the choke assembly is held together with one nut is that correct? The engine did actually start up and I was happy about that. I found that the lower unit shift shaft is stuck in drive. I gently tried to use pliars to twist the shaft with the...

    Need help to start 1984 4.5hp

    New to the forum. I just got a1984 mercury 4.5hp. I changed the broken water pump impeller and made sure it has spark using a spark tester. Tried starting it with a drill and the carb is just leaking on the bottom. Im unsure how to remove this carb off with the choke assembly right in the way...
