I'd replace the pumps
They're more than 20 years old, but more importantly, they've been unused for half that time. Everything in 'em has to be either rotted or corroded to the point where it'll cost you more to recover them than new pumps...and you may not even be able to get all the parts you need for 22 yr old pumps. Why would you want both an electric fresh water pump AND a foot pump at the galley? I'd replumb the whole system to work off a new SurFlo electric pump. If you plan to take the boat offshore for extended blue water cruising, and feel you need a manual back up in case of a power failure, plan your plumbing so that you can easily install a manual pump "on the fly" IF you should ever need it., but meanwhile enjoy the convenience of an electric pump. It's a myth that you use more water with an electric pump...you just have to learn not to let the water run. If water conservation is a real concern, you can even go with spring loaded faucets. Install an accumulator with the pump to keep power consumption to a minimum. I'd also install electric bilge pumps with automatic float switches and high water alarms, wired directly to your batteries. Also have a manual bilge pump as a backup...but electric bilge pumps protect your boat when you're not there to pump a manual pump--and even when you are there, but might not realize water is rising till your feet get wet when you go below. And as long as you're redoing all your thru-hulls, make sure your head intake and discharge seacocks are in a location that's convenient enough to be readily available to open to use the head, and kept closed at all other times. I'd remove and rebed every thru-hull if it were my boat (same for every stanchion, cleat and anything else that requires a hole in the boat). But you certainly shouldn't have to replace bronze, EVER...just clean 'em up. Talk to a pro about getting them out. And please don't rebed anything with 5200 (see discussion on THAT subject in the archives)! Use the proper bedding compounds for above and below waterline. As you "restore" the boat, keep in mind that recreating the original boat only has value if the boat is famous and will become a museum. The whole purpose of restoring any other old boat is to update it to state of the art. You wouldn't buy a 200 yr old house and keep the outhouse, gas lighting, and pump water from the well...you'd remodel with state of the art bathrooms, kitchen, bring all the wiring up to code--and install central heat/ac.. Same is true for boats...your sound old boat hull should be just the shell of a new one. Have fun! My last boat was a project boat...and I'm looking for another one. E-mail me when you're ready to start on the sanitation system...I'll help you design the system.
