Sounds like your water pump is right on the edge of not being good enough. The faster you run the motor the more heat it creats and the more water circulating you need. I'd go with a complete kit instead of just an impellor.

I have often wondered why OMC sold impellor's outside of a kit form, or installed overboard water indicator's, "Pee Streams" that has smoked a lot of engines

Might check or replace the thermostats while you are at it.
