Service quote opinion

[bobkatfly]

Looking to get some opinions on a quote I received recently from a marina on Winni.

Got a quote to do the following:

1) Replace sterndrive pump impeller.
2) Replace sterndrive bellows.
3) Replace anodes.
4) Sand, prime and paint some areas of corrosion down near the skeg.

Sterndrive is Volvo Penta DPS-B 2.32 and is on the boat.

Quote is $800. I don't have a real good feel for this so any experienced opinions would be appreciated.

Thanks
Bob
