welcome to iboats.

You need to drop the lower unit and make sure the new impellar is still in one piece and then carefully re-assemble. You may have missed the water tube seating properly.

Need to know what motor your working on. Are you trying to run it on muffs? Some motors are not designed to run on muffs. They need a special attachment or to be in a barrel.

Re: impellar replacement not working

In order for you to get the best advice you need to tell us what hp motor. 1970 covers a slew of Johnsons. Next make sure that you are testing this motor with plenty of water - - this means on the muffs or whatever or while the lower unit is completely submerged. A bucket don't cut it. Check this before you go nuts fixing stuff.

Re: impellar replacement not working

Looking at the evinrude site it looks like that year motor can use muffs. So I'm voting improper installation with the other. I'm thinking your going to need to tear it back apart and and check the key, tubes and the pump assembly.
