OK, i read over the Impeller change thread in the FAQ's, and it sounds like that is pretty similar to my 50. Is there anything much different than that to look for? How do you remover the rubber boot and collar at the top of the drive shaft without messing up the boot?

Re: Force 50 impeller change

I just changed the impeller on my 89 Force 50 hp today. 4 bolts at lower break point, then the coupling on the shift rod in the front right and center of the engine (lock nut). as you take the 4 bolts out, release the shift rod at the same time (little of this, little of that) - My lower unit just slid off. When off, at the bottom of the shaft - take off 4 bolts, pull shaft up and out of lower unit. Lift the water pump housing and impeller up the shaft, remove the pin for the impeller, then slide the impeller off the shaft, and the new one on (take note of the direction the fins on impeller are bent. Impeller only goes on shaft one way (see slot for the keeper pin in the shaft). When you put the shaft back into the lower unit spin slightly clockwise to insert -- when putting the lower unit up into the shaft insure the plastic spout on impeller housing goes into water tube in the upper unit, and put the shift rod in the small hole to reconnect.

Pulling the drive shaft is as simple as just lifinting it out? That shouldn't be too bad then. I actually just put a new lower unit on last week, so I'm good on all the rest. Thanks Dan!

I should say that mine came right out. I saw on another forum that there could be a nut holing it on at the bottom. If that is the case, that would mean you would have to pull prop shaft and gears (buy a seal kit) to get to it. Again, mine just slid out.

Well, we have the same year and hp, I wouls guess it's the same set up. Seeing how i have a whole extra lower unit sitting around I'll try it on the old one first.
