Reply To: Changing Impeller – How hard is it?

If you’re going to go to the trouble of dropping the lower unit, consider replacing the gear case seals (prop shaft, drive shaft, clamshell “string” seal, the shift shaft o-ring and the clutch yoke pivot seal).

You’ll also be able to inspect the lower end of the drive shaft and the whole prop shaft).

The procedure is very easy – just document what comes off and in which order and take photos.

The only special tool needed is a seal puller — I picked mine up at an auto parts store (Pep Boys, Advance, Napa, Autozone) for 10 bucks.
