raw water pump impeller

[highball]

I would like to know if someone knows the part number for the raw water impeller for a 2000 410 with 454 Horisons MPI.
I think I read somwhere that the casing is in plastic. is this true.
i can't look at the pump as the boat is still unfortunatetly covered for the winter.
I was looking last fall and couldn't see if there is an adjustment for the serpentine belt or a tensioner.
Just trying to get spare parts for the new season
Thanks in advance
:thumbsup:

Take a look at this post, I had 454 Horizons in my 2000 340.

Oh, and yes on mine the pump housing was plastic. In fact one of them had a hairline crack in it. It didn't leak, but I replaced it anyway.

Thanks for the info.
Will look into this as an early spring project.
