2003 Tiara 2900 Coronet
Twin 5.7 crusader captains choice engines carbureted
Starboard engine overheated and shutdown
changed starboard impeller w new. All blades fins had disintegrated on old impeller (see attachment of whats left of Sherwood impeller)
That fixed most of the problem
except starboard engine running 10 to 20 degrees hotter than port 
Think missing impeller blades are reducing flow maybe?
I see many others have had impeller blades disintegrate also.
Question: Where is the most likely, easiest place to look for the missing blades? Anyone with experience extracting detached impeller blades fins after the fact?
Ordered 2 more impellers, will replace port impeller before is does the same thing + have one spare.
