Should I change my engine water pump assembly as preventative maintenance? 2006 Mercruiser 350 MAG MPI

[ebg338]

Planning on doing some preventative maintenance on my '06 350 MAG MPI this fall. Was considering doing the engine water pump assembly (8M0113734). Not currently having a problem but it's original and now 20 years old. Engine has ~590 hrs on it and runs great, no issues, no overheat, fresh water only. Just curious on opinions given the age. Worth it as preventative? - Appreciate any input. Thanks

If its fresh water cooled, I wouldn't change it....if its raw water cooled, I may have a spare on hand...

they usually last a long time...as long as you take care of the engine..

Thanks for the input - it's raw water cooled.

Ayuh,...... The circulating water pump is extremely durable,.....
No need to change it, until, or if it starts leaking,....

If it's not leaking, I wouldn't worry about it- I recently changed the water pump in my 2005 Chevy Astro, at a bit less than 292K miles- unless the water contains sand/other sediment and/or is brackish/saltwater, it's going to last a long time as long as it isn't run dry.
