Re: impellers on volvo diesel engines
Is this something you're doing yourself or getting a marina to do it? If a marina, which one?

Re: impellers on volvo diesel engines
The pump is a Johnson pump and the impeller is 09-821BT-1.
I get them here https://marinepumpdirect.com/johnson-im ... 9-821bt-1/
There are a half dozen or so 8mm screws you need to remove to get the impeller pump cover off.
There is a thin gasket there I always replace, you can get that from Volvo, it doesn't come on the kit below.
The impeller has inner threads on one side and is designed to be pulled out with a puller. Hopefully the person that installed it last installed it threads out or it's a fight to get it out.
This is the puller you want.

The puller bolt is too short so take the bolt to a hardware store and get a longer one, maybe 1.5 - 2 longer", I forget how long mine is. Easy job with this tool.
To put it back in, use cable ties to fold the impeller blades in the right direction of rotation and lots of lube (comes with impeller kit). You slide/pull the cable ties off as you push the impeller in. Make sure the puller threads are facing out so next time you can use the tool.
Tighten the cover screws in a cross pattern (not too tight or they will break as they are very small).
Port side under 30 minutes, stbd side 1 hour plus depending on how good you are doing this without seeing.
Good luck!

Re: impellers on volvo diesel engines
Is the impeller change just regular/preventive maintenance or was there an issue that indicates the impellers need replacing?
