After closer inspection, I realize I am equally free to
replace (rather than rebuild) the ancient Henderson Mk
V manual bilge pump that has served Silverheels since
1978. It’s a big sucker, with a mid-section I haven’t
seen in similar pumps, with double inlets and double
outlets connected by a manifold, basically a long
double-L adapter. Perhaps all the 424’s came with this
workhorse.I’m poking around online, but has anyone already found
a replacement that fits the same mounting holes in the
lazarette’ s forward bulkhead (starboard end)?Thanks,
Tor

Edson makes one for like $600.
Pardon the brevity. I’m typing this on my phone and I hate typing on my
phone.

Bob, that’s not a replacement, it’s an depreciating investment. There has to be good, substantial manual bilge pumps available for a lot less than that. Hasn’t there? Is that what you put in your boat?
Pete, Alan, Rich, anybody? (I know, it’s the 4th of July. It’ll hold ’til Monday.)
Thanks, Bob.

Tor,
I replaced my pump several years ago. It was a Henderson and I found that
Whale still produced that pump. However, it is not nearly as robust as
the pump you describe. Sounds like something a PO installed. Certainly
not something Pearson would provide.Regards,
John Stevenson

Tor: I replaced my original last year with one that fit the same mounting exactly. I’m sure it was the same manufacturer (Henderson?) and didn’t cost that much. My boat is a 1980 and the old pump had to be an original. I replaced all of the tubing/fittings to it at the same time. I’m not aboard right now (in JoJa) to conform the manufacturer. Remember, pump capability is directly proportional to motivation!

I’d check to see if Whale has replacement diaphragms for that before I’d empty a fold in your wallet. I remember seeing something about a rebuild kit when I first looked back in Nov. I just never followed through and found it.
Ken -
Roger that, Ken. I started out this afternoon with the
same idea, but if you saw the condition of this old
pump you’d understand. Just getting it apart would be
pretty labor intensive, with no guarantee it’ll come
apart in the pieces it’s supposed to. Sometimes it just
makes cents to replace rather than rebuild.Then again, I haven’t priced replacements yet.

See my online cache of 424-related manuals including lots of whale pump manuals here : http://www.dublerfamily.com/Regina_oceani/Manuals/
(I’ll add the edson stuff we got earlier the week when I at at a real computer soon)

I have found the whale rebuild kits to be reasonably priced. Shop the web.

I rebuilt the cockpit manual pump recently. If I recall correctly Henderson became Whale and they had the rebuild kit. In any case I am pretty sure I got it from fisheries supply.

Unless the case is broken, rebuild. Very easy and effective job.

Tor,
If you’re talking about the whale pump mounted on the cockpit wall, there
are still rebuild kits for it and it’s a good pump. I added a second down
below so that I could pump the bilge or the holding tank when the electrics
fail.I thought you were talking about a crash pump, mounted on a board for when
the caca really hits the fan, pumping a gallon a stroke. That’s the Edson
one.Bob

I agree. For what it’s worth. If the epoxy coating is bad, clean the
aluminum up and re-apply a thin epoxy coating. Doesn’t have to be yellow.Bob

Amazing what a good night’s sleep will do for an old
bilge pump. Late yesterday it was shot, worn out,
un-fixable. This morning it seems to be saying,
“Rebuild me! Rebuild me!” I’ll have a fresh look at
that shortly. I’m pretty sure Whale bought or otherwise
absorbed Henderson and provides parts for them.Thanks for the feedback.

Thanks, Pete. Once I see what I need I’ll know what to
order. Clearly there are many variations of the
Henderson Mk V manual pump.Tor

Yellow? Three of my Henderson’s are black, one is
white. All appear to be made of heavy-duty plastic
except for the unpainted cast aluminum mid-section of
the bilge monster.Tor

Top o’ the morning, Bob,
Attached is a photo of the alleged pump, a Henderson Mk V according to its inscription. With this morning’s fresh outlook, I am determined to rebuild it. Until a few days ago it was working marginally, but working. Then it quit drawing altogether. I doubt I’ve ever known it at its full capacity. It looks like at full capacity it could suck a bilge inside-out.
While I’m at it I’ll also rebuild the holding tank’s manual discharge pump and, at long last, install the Y-valve I bought to switch its intake between the tank and the bilge. It is also a Henderson Mk V, but smaller and with single ports.
In addition, I have a third, never-used Henderson Mk V – I believe it was on the boat when I bought her – much like the big bilge pump I just removed, but without that massive mid-section and sporting a slightly different mounting footprint.
Last and least is a smaller Rule “crash pump” mounted on a board, which I’ve used once or twice over the years to assist small vessels in distress.
That’s a lotta’ pumps.

Thank you Pete! I knew there was rebuild out there.

Shaka, bra.
I’ve acquired and lost any number of accents over the
years – New Yawk, Southern, Western, Hawaiian, West
Indian… all the sillier because I grew up with a
Johnny Carson-like non-accent. I think the most
surprising change occurred when I lived for some months
in a small Venezuelan marina aboard my Crealock 37,
Sparrow. Hung out with a bunch of local buddies, had a
Venezuelan girlfriend, didn’t hear or speak English for
weeks at a time. I actually started speaking English
with a Latino accent. Didn’t even realize it until I
called someone back in the States and they commented on
it, thought I was joking. Funny how those things sneak
up on you.

I don’t think your pump is original. Mine was on the starboard aft end of the clockpit near the helmsman’s leg.

We may be talking about the same location, Rich. I reach the mounting nuts on mine from inside the lazarette’s forward bulkhead, off to starboard.
I gather my mega-pump is an upgrade over the standard issue, and an expensive one. Bob Fine pointed out that the double ports enable it to inhale and exhale on every stroke, rather than one stroke in, one stroke out, effectively doubling its capacity per stroke, basically two pumps in one. I am certainly going to rebuild it. My thought of replacing it with a new pump was a mere moment of weakness, exhausted laziness, at the end of a long day.
