My Hunter 340 came (to me) with a Rule bilge pump, it is the kind that automatically fires every 7 minutes. If there is no resistance on the pump, indicating no water to pump out, it shuts down. So far this season (May – September) the pump has fired 70,000 times according to the counter at the Nav station.
While I appreciate the security of a pump that is always checking, I can’t imagine it is doing anything but slowly, unnecessarily wearing the pump out. It also makes a racket that I’ve gotten used to. Given I’ve got solar panels I don’t worry about the battery drain either, but that could be an issue for some owners.

I’m a big believer in details, perhaps it’s my training as a goldsmith or a pixel perfect developer, but if there’s a speck or a design flaw it will bug me. Having a white boat is a lesson in finding serenity, I swear there is someone out there laughing at all the scrubbing boat owners do.
Having a brand new high-pressure water pump with a faulty shut-off sensor (the backstory) gave me the perfect opportunity to fashion a wash-down pump. A bit of hose, a few clips and away we go!
With 40 psi and 17 liters/min the cleaning possibilities are endless!
The fridge door/lid always made a screech when opened and the gas strut was very stiff. I found a bunch of gas struts on the sale table at Princess Auto for $4 each and they seem to be close to the right size. I only noticed when I removed the old one that there is a manufacture’s sticker and model number.
I only noticed the brackets were not in the same plane when I put on the new strut. I relocated the brackets to get the door to shut, but also the bottom bracket needed to come over by 3/4″ to line up.
The bottom bush was drilled out to fit on the existing stainless post and luckily the top fitting works!
UPDATE: Fall 2017
The cheapo strut didn’t last the season so I splurged on a new strut (It was only $13 !) I choose one from Amazon based on the weight of the lid. Here are the specs:
Load : 170N ( 17Kg)
Hole Diameter : 4mm / 0.16″
Rod Size : 172 x 6mm / 6.8″ x 0.24″
Hole Distance : 408mm / 16″
Total Size : 430 x 15mm / 17″ x 0.6″ (L*D)
After a full summer of cruising here are my thoughts.
The piston rod is a bit on the thin side but it doesn’t bend, in the future I might get one thicker but I don’t think it really matters.
the ends have plastic caps like automotive ends, they do snap onto the stainless mounts and only fell off once or twice if I really impacted the strut. It did come ball-end mounting hardware, but I thought I would try it and it seems to work. I could drill out the plastic caps and fit the circlips if falling off was an issue.
the struts lift is stronger than either of the two, it takes some effort to close and I had to put on two latches to keep it closed (which is how it came from the factory in the first place.
The first pump died after 15 seasons. It sounded like a jack-hammer but was a reliable crew member on our boat, sort of like Relic on The Beachcombers. Part of my bedtime ritual was turning the breaker off so as not to be awoken but sporadic bursts of pump.
This pump was made in the USA in 1999 and judging by the date, I’d say it was the original freshwater pump. It started weeping at the end of last (2014) season and I ignored it. At the end of this season, shortly after finishing out trip to the 1000 Islands, it quit (almost exactly like the fridge did last year). Upon inspection the inner sealed-bearing failed and flooded the electric motor. Rust-brown water trickled out of the motor case, it was done.
Every fall I re-research which liquid to pour into my boats many freshwater systems. I find I keep coming back to the blog by Practical Sailor author Drew Faye, Sail Delmarva.
I particularly like the fact he has researched his opinions and they are based on fact. So here are his winterizing suggestions:
Pump out the potable water tank. Vacuum out the remains with a shop vac.
Add a shut-off valve and tee just down stream of the tank and upstream of the pressure pump. Add a second valve on the tee’s side branch and a length of 1/2-inch ID hose. Suck a 30% propylene glycol antifreeze mixture into all of the lines using the pressure pump, opening the taps one at a time (hot and cold) and letting them run; the clear water goes down the drain until it’s as pink as the feed (you can recycle some of this by boosting it with with concentrate). When finished, remove the suction hose from the antifreeze container and blow out the lines with the pump by letting it run dry for just 20 seconds per tap (the glycol lubricates the pump, so it will not be damaged in a minute). If you have a tank water heater you should drain it and bypass. I have an instant heater and the above works well.
I opened the cartridge and found that there is a o-ring that sits atop the upper ceramic disc that appeared to have been pinched. How this happened I don’t know. Perhaps it swelled from the alcohol in the antifreeze?
