If impeller is good, make sure you check the housing as well. You may want to take the thermo out and put it in hot water to make sure it is working right, or replace. If those three things are good move on to oil cooler being blocked by old pieces of impeller (end caps are easily removed). Next is scale from salt water use that may release and clog ports around thermo, recirculating pump, exhaust, causing poor flow. And last is the fitting between drive and transom can sometimes become clogged, collapse, or have a small leak that reduces flow.

I'd probed it before, from the top, and it felt like rubber so I ASSumed that was the hose on the bottom. Fast forward to today and I finally managed to remove bottom hose and immediately chunks fell out.
Moral of the story- don't be lazy.
