what tools do i need to change a impeller and housing on a 2005 525 efi motor. im doing it for a freind and need to take tools with me.

1/2 wrench socket and extentions for the housing. 5/16 nut driver for the hose clamps

5/16 and 5/8 wrench for the belt adjustment

You sure don't need much. It's a 20 minute job.

Socket set

Flat head screwdriver

oil to lubricate impellar

I would replace the housing along wth the impellar.
