[C320-list] Impeller Replacement

[Amirault Family - S&B]

All:

Bear will be starting her 4th year of service with me on May 01. When
acquired in 2007 one of the many things done to her to benchmark engine
maintenance was replacement of the impeller. I do not remove the impeller in
the fall. I put 20-25 hours on the engine each year. Can the current
impeller continue in service or are there time/deterioration issues that
demand the impeller be replaced more frequently despite the low usage?
