Re: How easy to replace an impellr on Johnson?
I had to chisel the impeller off of my '97 115, chiseled right through the rubber and then the brass insert inside of it that slides down the driveshaft, being careful not to hit anything else, once I bent the insert a little with the chisel, it came loose and up the shaft...PB Blaster definitely helps too.
I never try to fit the cup onto the impeller separately while it's on the shaft, I twist the impeller into the cup first and then slide the whole thing, with the housing onto the shaft as an assembly. Just remember that if you do it this way, you are looking at it upside down, so you have to twist the impeller in the correct direction. Slide the whole thing down and hold the key in place with a popsickle stick, work it onto the key and it will drop right on, pull the stick out slowly and it will go the rest of the way down, then just bolt it down, have done it that way 5 times in the last 2 years on various engines, way easier than trying to spin the driveshaft to get the impeller to seat in the cup.
I like the zip tie idea too though.
But either way, getting that LU down is gonna be easier with the carbs off.
