Has anyone figured out how to install the high water sensor on a 25XP? I replaced the harness and engine panel last year, and it has the capacity to have the high-water alarm (alarm to indicate high water temperature), but apparently there is no thermostat cap/housing for the XP that can accommodate both the temp sensor and the high-water alarm sensor (at least according to Torresen and Hansen). If you did this upgrade, did you drill and tap a hole for the sender?
Jon - I bought the cap from the local Universal distributor, but there's no reason you couldn't drill & tap the existing housing. The worst thing that would happen is that you'd have to buy a new cap.

Craig, do you have any idea of the part number? I assume your cap has two entry points, one for the temp sender and the other for the high-water alarm (why they can't combine these two functions is beyond me)? BTW, these caps are about $100, so I'm less than thrilled about experimenting with one.
Jon - p/n 200262 for the housing (from the Seaward data sheet). I see it's $105 at Torreson. I don't think I paid that much for it. Check with Gallery Marine here in Seattle. http://www.gallerymarine.com/
I hope I didn't toss my old one, I should have been selling it on eBay. I'll have to check around.
Craig
Jon,
It's very easy to drill and tap a new hole for a second sender. The housing is aluminum and easy to work with. I've attached a photo showing both senders installed. Hope this helps.
Jon : Another Idea :
You might also ask Seaward if they still have the old Hi Temp Alarm that turned the analog (when it reached 190/200F) to a digital signal and the alarm buzzer would sound. Ask for Dave Gardner.
Have had one of those since 1990! Also installed a "press to test" toggle switch so I can check that the alarm is working!!
Wrote that up in the Mainsheet about 18 years ago. :D
Thanks Ron; that's a neat trick that Seaward developed, but I upgraded to the new engine panel last year, so I've now got a light and an alarm built in. Just need to connect it to a sender!
Jon : FYI, I also have a new panel and both the light and the buzzer go off when the temperature is over 190! What I did do is to replace the meek Seaward buzzer with one from Radio Shack which is MUCH louder!!
Now it can even be heard in the galley when the engine is running!! :thumb:
That's a great idea, Ron. Any particular buzzer from RadioShack, or just any one that fits?
Jon : The way I selected mine was to take two 6V lantern batteries (in Radio Shack) and put them in series so you get 12V.
Then I picked the loudest one!! :thumb:
I'm surprised they didn't kick you out of the store!
Jon,
I installed a new panel, harness, housing and sender last year. The housing cost me 96 bucks. I sure wish I had just drilled and tapped the old housing (which I still have) and saved the $. Live and learn.

Steve, you gotta look at it this way: you helped postpone the collapse of the economy... every boat buck counts ;)

Craig, are you sure that this is the part number. I just received it, and it doesn't have a second hole for the high-water sensor.
Jon - That's the number I got off the print from Seaward. Maybe you received old stock? Who did you order it from?
Craig
Ah, okay, I thought I vaguely recognized the number. I ordered that part last year with the same result (just the one hole). Guess I'll go the drill-n-tap method. Now, at least when I screw up, I'll have a back up ;)
Sorry to bring up an older thread, but the topic is just about right.
Does anyone know of an appropriate Temperature Switch? (I'll be drilling and tapping my older Thermostat Housing and would like to keep the hole as small as I can)
I've seen some automotive applications such as "Auto Meter" for about $20, but they look wide and shallow.
The Cole Hersee switch and/or kit has a 3/8" thread. http://www.colehersee.com/home/item/cat/225/84251/
Westerbeke's 30125 seems perfect with the 1/8" thread. But I was a little surprised at the cost from Toressens $49, and even more here in Canada $67.
Also, I've never tapped NPT (tapered) before, guess I need to get me an NPT tap., I've only got NPS.
Suggestions?
Steve
Steve,
I'm in the same situation and really feel $50 for the switch is out of line. Since the switch is only open or closed, I don't see why you could not use the Cole Hersee 84251 ($15). I may go ahead and wire it up and see what happens. I've been talking to Seaward Products so I'll try to run it past them also.
Cheers,
Rick
As you said it is just an on/off switch. check with your local auto parts store...with a little research you should be able to find one that works at the appropriate temp. Might beat the Cole Hersee price.
A quick check on outside diameter of these NPT fittings shows that for 1/8" NPT, the OD is .405" and for the Cole Hersee 84251, 3/8" -18 thread it would be .675". That's a pretty big hole!

I'll go by my auto parts shop and see what the guys can come up with, but it seems now-a-days they want a model and year for their parts look-up.
Will advise.
Steve, I hear ya about parts lookups these days in auto stores. We have two kinds of auto stores around here: the big box Kragen/Napas of the world, and still one or two "family owned" or smaller chains that actually have guys behind the counter who know something about real parts. I buy my filters at Napa, and use the smaller, knowledgeable guys for the more interesting parts sourcing. Jamestown and McMaster Carr are reported to have a wealth of "stuff," too.
Steve,
Thanks, I totally missed the size difference and would have been surprised when it showed up. Now I'm have trouble finding a 1/8" npt temperature switch. I might be stuck ordering the $50 part.
Cheers,
Rick
Hey Rick, I did find a few other suppliers in the US that you could consider. Unfortunately some won't ship to the great white north.
The one for $25 almost seems too good to be true; not sure if it is a trusted source. They won't ship to Canada, but it may work for you.
Torresen's $49 + $1 connector + $2 isolator + Shipping.

Discount Marine Source in Michigan has it for $44.80

http://www.clrmarine.com/ sells for $44.80, but their distributor uses only UPS, however, email with Chuck and he can make it work by having their distributor mail it USPS.
Good luck, oh and if my hint about an NPT tap wasn't too obvious it's something you'll need otherwise the effective threads will be limited to only a few. Although there's only what ,13 PSI in the system, may as well do it right.
By the way my parts guys couldn't come up with anything, so I'll likely order from clrmarine.
