It appears the fresh water pump gave up the ghost last night. I'm wondering if this pump is the OEM or an upgrade by a PO. The existing water system has a Jabsco 36900-1000 4.2 GPM pump (see the manual here: http://www.pumpagents.com/pdf/JabscoPumps/36900-1000.pdf). Online this thing sells for about $600!!! I've uploaded a photo for reference.
I also have an accumulator tank.
I've seen others posting about having Shurflo pumps. And I was reading Bruce Landsberg's article about his plumbing system upgrade in the Technical articles
(https://www.catalina36.org/members/technical/upgrades/plumbing-system-ma...)
So, can I pull out this old belt-driven pump and the accumulator tank and replace with some model of Shurflo pump? I see on the Catalina Direct site a reference to a model that is 3 GPM. Are there other recommended models?

Hi Doug and Mary,
We acquired our '83 15 years ago, and it already had a Shurflo pump installed. Not sure if it was original. The pump hasn't needed any maintenance in the time we've had the boat. Won't see the boat again until April, so I can't verify the model, but I would guess it's the 3.0 GPM unit that Defender has on sale right now for $113.15 (model 4138-111-E65). Beats $600!
The system on my boat seems quite simple - the two water tank lines run to a "T" connection, and then the single line goes to the pump. I have no idea if other C36's are plumbed this way, but I can tell you that this setup has worked just fine on our boat for 15 years.

Doug,
The Jabsco belt-driven pump in your boat is not OEM. It is an on/off pump, hence the need for an accumulator tank. Newer design pumps are variable speed, and do not need the accumulator tank. I can second the recommendation for a Shurflo pump. I've had one for the past 6 years and it has been flawless. If you slightly open a faucet, the pump works slowly and quietly, with a steady flow. Open the faucet all the way, and the pump works faster, pumping a higher volume, also with a steady flow. My guess is that you want one with a 3-4 GPM flow rate, and you can do away with the accumulator tank. Hope this helps.

Tom,
Thanks for that. I did buy a Shurflo (4 gpm), and it is working great. A bit of an adventure getting it mounted on the existing platform (tight quarters to drive the new screws in). Patience was a virtue.
