Re: 1993 150 Johnson 60*
there was some changes in the VRO pumps, I am not sure what years the changes took place or what the changes were. But if you want to be sure it will work you will have to break down and get a new pump I guess..the new ones are supposed to be a better design, but who knows..I put a brand new 5007422
on my 1995 150 rude and it works great, been on less than a year though.
