It should have something coming out the tell tale at idle….and of course, above idle. Never trust a Merc impeller of that type, any more than two years. They take a bad set and sometimes come undone from the impeller hub. Hey, at least that one has a stainless drive shaft. An impeller shouldn’t be too big of a deal. Just be gentle putting the lower unit back on. Don’t force it. It’s possible to bend the purposely-bent water tube even further. That’s a little complicated to fix right.

Long live American manufacturing!
