omc impeller question?

[SportPhish31]

Kind of a dumb question but do I need to replace my impeller? This is the original on the 86 searay seville with an omc cobra. I recently bought the boat and went to start it on muffs and I noticed it was running kind of loud and hot also, there was no exhaust water. So I checked the impeller. This is what I found. Is the housing suppose to be oval?

Usually an impeller won't make it 26 years, I suspect it was changed several times.

Anyway, yes, get a new one.
See the worn edge on the fins?
See the "set" a couple fins have taken?

Easier and cheaper to change it out than to have a failure and due severe damage.

The impeller is offset in the housing, Thats how it creates pressure and pumps water.

Especially, 'cuz you're already in there.

Yes, the housing is sort of oval. Non-round, anyway.
Replace the impeller. Yours is very worn, and do you want to risk an engine over a $20 part?
