Sorry this may be a dumb question but i just replaced the impeller on my newly aquired merc 3.5. I cant get the lower unit back on. Is there some special trick to getting it to match up? Any help would be great

It's probably about the same as my 9.8..someone here gave the tip of standing the motor on it's head, so you are looking down the mid section. Make sure the lower is in the same gear as the shifter..then twiddle the shift handle till you see the coupler part in the midsection line up in the hole. Then slide the lower on making sure your water tube goes into the guide(you might want to lightly oil the water tube so it slides into the grommet easier). I have to jiggle the shift lever slightly so the shift shaft and coupler line up. It may take a couple tries but it's a 100 times easier than tring to do it with the motor right side up.
