I just bought a 79 standard rig with fin keel. My first 'big'boat. Great to be in the Catalina family. My boat has no manual bilge pump which is making me a little nervous and I would like to install one this spring. Any suggesstions on brands or specs? I good friend who works in a boatyard will install it free for me.

Hi Ella, welcome to the Catalina family. I'm new as well, just got my boat 2 months ago. My 1982 C-25 has a Guzzler manual bilge pump that was originally installed in the cockpit inside the storage locker. Here's a photo from the inside of the locker:

I have a concern about my bilge pump setup as well. The previous owner installed an automatic electric bilge pump under the aft dinette seat and connected it to the original manual bilge pump hose in the locker. They disconnected the manual pump, so I cannot use it as a backup. There is a handheld bilge pump stored away, the type that looks like a big water gun with a hose attached. I'm wondering if the location under the dinette seat is an okay location since the original picked up water lower at the keel near the steel cable/winch. How do others have their bilge pumps setup?

Welcome Ella,

Here are a couple of links you might find usefull: [[url="http://www.sailnet.com/collections/seamanship/index.cfm?articleID=caseyd0044&coll_cat=Safety&Coll_name=Safety"]Devising a Better Bilge Pump[/url]] and [[url="http://www.boatus.com/boattech/casey/14.htm"]Installing a Bilge Pump[/url]], both by Don Casey.

In refitting my 1979 Catalina 25 for coastal cruising, I installed a 3-pump system very similar the what Don Casey describes above, and in his excellent book, "This Old Boat".

1.) The smallest automatic electric I could find for slurping up small amounts of bilge water. I then further restricted its capacity by using a smaller diameter discharge hose than specified, so as to minimize drain-back.

2.) A 3,700GPH damage control pump. It's capable of staying ahead of a 1-1/2" diameter hole a foot below the waterline. If installed, perhaps this one should also be wired to sound an alarm in automatic mode.

3.) A manual bilge pump operable by the helmsman. For when the two electric pumps have failed to do the job, but the boat hasn't yet sunk or reached port.

You may decide to only install one or two of those three. Just thought I'd mention that approach. Each bilge pump discharges through its own thru-hull well above the static and heeled waterline. I installed my bilge pump thru-hulls just inboard of the outboard motor. The electric pumps are wired with separate over-current protection, and do not draw power through any other main power switch, selector, or circuit breaker.
