raw water pump replacement

[capnbgm]

I have purchased the Oberdorfer n202m-15 to replace a Sherwood raw water pump that is leaking badly.  The Oberdorfer has smaller ports than the Sherwood--3/8 inches.  Can anyone recommend where I can find appropriate size elbows for this pump so I can connect the raw water hoses?  Thanks.

You want male 3/8" NPT to hose barb of whatever inside diameter your existing hose may be. If you get lucky they will be in the plumbing section of your Lowe's or Home Depot. Otherwise Amazon, for example:

Negative.
It's HOME Depot, not BOAT Depot.
You need Marelon or Bronze fittings.  Brass from the home plumbing store leaches out the zinc resulting in brittleness.  Last thing you need is a failed plumbing elbow below the water line on Christmas Day with 6" of snow.  Or without the snow.  It's a bad deal.
I've got tons of suppliers for these; the one that is most accessible to the common boater is defender.com

Ah, I see our boat expert is back online! Good to hear from you, Mr. Moonlight.

I stand corrected; I should have pointed out that boat fittings must be bronze, not brass, regardless of where one buys or orders them.

However I must respectfully correct your chemistry. It's the zinc content in brass that causes problems. The zinc leaches out galvanically and leaves the fitting weakened. Bronze contains no zinc.
