Title: Sherwood Sea water pump
Post by: Ken Juul on October 07, 2005, 06:42:26 AM
had guests on board last weekend, got distracted, left the dock with the engine thru hull closed.  Caught my mistake before we left the marina, tied up to an open t dock.  Impeller was still in one piece, but several vanes were starting to tear.  Installed the spare and had a great weekend.

In searching for a new spare impeller I looked at Defender.  They were advertising a new blue model manufactured by Globe.  15 minute run dry guarantee.  For my 25xp,Sherwood impeller Part# 9000 the correct Globe part # is 610.  If you have the 10077 impeller the corresponding globe part# is 1130.  It does not come with an O ring and gasket, the price is $27.99.  Got it yesterday, exact match.  Vanes are a little stiffer than the rubber, and the plastic has a slippery quality to it.

If you decide to stay with the black rubber kits (with O ring and gasket).  Go2marine.com has them for $29.16, adiesel.com has them for $30.06.  Both cheaper than BUS or WM.

Ken : I put that same information in the Fleet 12 Newsletter about the Globe made impellers from Defender, over a year ago.

I've used the Globe impellers in my Oberdofer since 1991!!  They are much more resilient than the "black" ones.
I've NEVER had a blade detach.  Change mine out every 3 to 5 years when I might see a slight cracking in the blades where they attach to the hub.  Good impeller.   :thumb:

Hey Ron,

You don't by any chance remember the model No. for the globe impeller for the oberdorfer?

Steve : The number for an Oberdofer pump is "Globe" # 815.  I believe the Defender part # is 301961.  Think the Oberdoffer impeller is a little cheaper @ $15 -20.

What makes the Globe impeller different is that it's made out of "Elastomer Niprene".  They are a dark blue in color.  Years back they used to call them a 'Barko" impeller made by the Globe Rubber Works.  
I wrote a TIP in the Mainsheet years back.     :D

Ron, Thanks.   FYI-  Defender is offering the 815 impeller for $15.82 as a "boat show" special.  Torrensen Marine offers the std black rubber impeeler for $34.95.  I've been accused of having no brain, but I don't thnk I need one here.

Steve and Ron,

       Thanks for the heads-up on the good deal from Defender. I just ordered a couple spares.
