Bilge Pump in Cockpit

[BlameItOnBuffett]

Thought I would start a new thread on this since it was buried under a totally different.

What I got from another owner was that it was a henderson Mark V. I was able to finally confirm this. However, the one you see online or in the catalogs does not show that handy trim ring (which is missing from mine and would allow intrusion if the cockpit ever filled). I contacted whale, and was told that it was part number DP 9905.

It doesn't come up on West Marine despite the fact that Whale says they have it. I don't believe it comes with any new Mark V...

When you search Defender for dp9905, you see the white six holed trim ring with rubber boot. It says it is "
  Replacement Deckplate  - Deckplate white w/o lid (old type U/D & D/A pumps only)... " and costs 27.99.

I am going to check West Marine. Their site has the right picture, but with "Manual Waste Pump Service kit (WM#516070 - MFG #AK8050). http://www.westmarine.com/webapp/wcs/stores/servlet/ProductDisplay?storeId=10001&keyword=516070&jspStoreDir=wm51&productId=79814&resultCt=1&catalogId=10001&ddkey=SiteSearch If it includes it witih the rest of the service items, then that would be the better deal.
