General stuff on water pump failures such as
http://www.usmotorworks.com/customers/catalogs/WHY_PUMPS_FAIL.pdf
list electrolysis and cavitation as among causes.
At other sites found dramatic pictures of pump impellers and other cooling system parts badly eaten by electrolysis or cavitation damaged. Of course most of though were in auto engines..but same idea. Coolant and impeller doesn't, know if it's in a plane or car :S
Curious (referring to the recent post here discussion of pros & cons of waterless coolant) if Rotax water pump failures/replacements are common, rare, or extremely rare. AND if electrolysis or cavitation damage are common or rare causes?
Reason for curiosity is one of the claims of the waterless coolant tha Rotax sometimes recommends is it makes electrolysis impossible and cavitation less possible.
So depending on how common or rare those are as causes of Rotax pump replacement would make a stronger or weaker case for using the waterless coolant.
Anyone have any field experience or info that might answer suggest how rare or common water pump failures and electrolysis or cavitation damage are in 912 types?
