At first the impeller blades were bent but they straightened back out over a period of about an hour.

Yup. Like I said in the previous posts, it's always a good idea to change them. And anything dry rotted, cracked, burned, torn and worn gets the heave-ho instantly. But I was basing my "looks ok" comment on the fact that it looked like the impeller was just pulled out of the housing when the pics were taken, and given that short time period there's no way that the vanes would straighten out right away. I have the same engine. I know it takes a half hour or so for them to straighten out after they have taken a set from the housing. The cracking however is a game killer. Time for a new impeller.
JCK, they do make an entire kit (Housing, plate, impeller, key, and gaskets) I think I have one at home. As soon as I get home I'll see if I can find it and post Mercury's part numbers for it off the box.
