Bryan,
Thought I'd copy your link and start a new topic for "water pump" in the tech section. Hope you don't mind :D

http://www.jabsco.com/prodInfo/overview ... 607_ds.pdf


This is interesting! I copied and pasted two paragraphs.........Don B

OPERATION
The pump may be run dry for short periods of time.
However, running without liquid allows heat to build up
between seal faces, thus shortening seal life. The pump
can run against a closed outlet such as encountered
when using a garden hose type shut-off nozzle.
Small
particles of trash and debris will pass through the pump,
though an intake strainer should be fitted if excessive
problems are encountered with pump clogging.


INSTALLATION
The pump must be mounted in a dry location – the motor
is not waterproof and must not be submerged.
The unit
can be mounted in any desired position. It is best to
mount so that water dripping from loose port connection
will not wet the motor.

Don, that's great! I think we've concluded that restricting the flow somewhat should not cause any damage to the pump end.
However, I wonder about the electric motor end and I'll admit I don't know much about electric stuff. So maybe we can get some of you guys who do know to comment.
My thoughts are that if you put a heavy load on the electric motor by restricting the flow on the pump end, it would eventually blow the 10 Amp fuse which also has the fuel pump wired to it. Ultimately the bike would shut down shortly after the fuse blew.

Hi Ed!
You've been looking at this for a little while now. Are you going to "take the plunge?" Do you know if it will fit where the pump we have now is?

I'm curious. What is the issue with the "boat" pumps we have???

All I hear is that people are installing screens, bug shields, cardboard bull**** and putting higher limit switches for the fans so they can get their operating temperatures up..........obviously the pumps and radiators are doing a sufficient jobs of cooling........except maybe the big blocks with the old style radiatiors.
I'll keep my "boat" pump thank you very much.

I had a water pump **** the bed when I only had 2000 miles on my Boss. When the factory sent me a new one under warranty and I read that it should be mounted in a dry location because it was not water proof I haven't trusted it since . One thing I did do before I installed it was I siliconed all the seams , screws and wire exits and it hasn't let me down yet with 29,000 miles on my Boss . I do wish we had a better quality pump though .

Jack,

Better quality in what respect??? When you consider the environment that pump of yours has been in for the last 29,000 miles, it's pretty impressive. Just watch the vibration it endures at a stop light 8)

That pump that Eddie linked to looks really good............but I wonder what kind of life span it has compared to our boat pumps. Is it designed to be out in the open it's whole life??? Street rods and dragsters have a very limited run cycle.......sometimes violent in the case of a dragster......
but short just the same, and you don't see a lot of high end street rods routinely driven in the rains that Eddie endures on his annual odessy.
Just my $.17 worth (inflation is hell, cripes premium gas here is $2.15)

Time to go back to a Honda :lol:

I have 36,000 miles on my pump and the only thing I have done to it was to put a chrome cover over it. I doubt that helped it any but it still works just fine. I know when it gives up I will get a new one or set up a mechanical type like a few guys have.

Don,

Who said you could have 81 degrees today in New York?? Man at least share a few degrees for us poor souls in the midwest.

We have contracted a professional hit on Radu.........figure thats' the only way we can get that darn door up there closed.

If I didn't have that problem with my first pump at 2000 mile , maybe I'd have more faith in the pump . I guess it's like the tranny's . If you get a bad one it's going to break . If you get a good one it may last who knows how long . Tranny or water pump , if they break your dead in water or on the road in our case.
I'm sure glad I'm not broke down somewhere waiting for my powermaster starter . I ordered it 2 weeks ago and am still waiting . They said they are on back order and won't be shipped until 5-19 -04 . I guess if I ever do break down and need a part overnighted to me in east bum **** , I'll call Levi .

Tim - the pump is a BOAT pump and not recommened for auto use don't shoot the messenger.

Don - yup if mine goes I'll go for a pump engineered for auto use not one for pumping boat hulls.

Eddie, et al,

I have tried to remain silent but I can't resist any longer. I have to "get my oar in the water".

You can classify the Jabsco Pump with whatever heading you want but the facts are that there have been almost NO failures of this pump. It is a low pressure, circulation pump with ceramic seals and uses centrifugal technology (the same as a standard automobile water pump).

No one knows this but I have been working with the Product Manager at Jabsco to trial a new pump that is a good application for the Boss Hoss. Our existing OEM Jabsco pumps will pump 15 GPM, free flow and have a cast bronze pump impeller and pump housing.

The new pump I have been testing has a stainless steel pump housing and impeller. The impeller is machined for better flow. And the chamber has been redesigned with an elliptical shape (like an automotive water pump) for better flow. The 12 Volt electric motor has also been completely redesigned. The new pump flows 26 GPM, free flow. While it is true this pump is not designed to be submerged, it is water resistant and is perfectly suited to the Boss Hoss application.

It is essentially a "bolt in" replacement for the existing pump. It uses the same 3/4" NPT female inlet / outlet in the same configuration as our original pump. The mounting pad has slightly different dimensions but still has four slots with rubber grommets and the pump can be mounted to the original water pump pad with slightly longer bolts and a little bit of encouragement.

The pump is quieter, pumps more water and still draws 10 amps under load (the same as the original pump) and the motor is shorter.

While I have this pump installed on my 2003, 502 and I have made additional modifications to the cooling system, it definitely cools the engine another 5 to 10 degrees depending on ambient conditions.

This pump is now available from Jabsco through any of its many distributors. Its part number is 50830-0012. If anyone wants to purchase one and is having trouble locating a supplier, there is a distributor here in Tampa who will ship anywhere.

I plan to document fully my modifications to the 502 cooling system in the near future (either in a Boss Hoss Country Article or on the Forum boards). I have made significant progress and my Trike is very livable here in Florida.

Water Pumps - More

Water Pumps - Shogun Industries

Fast Eddie made us aware of a water pump alternative offered by Shogun Industries http://www.shogunindustries.com/cgi-loc ... s400CS.cgi. I sent an email to them to learn more about their water pumps as their web site gives no technical information.

I was pleasantly surprised to have Bill Shoquist call me from Shogun. Following is a summary of the information he provided me. I am simply passing along the information he gave me. I have no personal experience with Shogun products. Marv Jorgenson, Chopper City, Boss Hoss Dealer in Minnesota is working with Shogun to develop the Boss Hoss application. I would suggest you contact Chopper City if you are interested in this pump.

Details given me by Bill Shoquist:

-The pump is a displacement pump (elliptical chamber with a flexible impeller).

-The motor is a first quality 12 volt motor with quality components and ball bearings. Bill assures me this motor will last as long as any 12 volt electric motor available.

-Bill has approached the cooling of an automobile engine as a "system" rather than just swapping out the pump. Therefore, application of his pump is not just a pump replacement but rather installation of a cooling system. Some of his creative work is to reverse flow the coolant so as to cool the hottest part of the engine first - the heads.

I came away from my telephone conversation with Bill feeling he was a very knowledgeable guy and that he really cares about his product and its application.

Due to the need to install a "system" rather than just swap out a pump, I suggest anyone who is interested in this pump contact Chopper City.

All the newer Corvette's use the reverse cooling and by doing so they picked up 20 plus HP with that alone. I like the idea and may very well look into doing it if it is feasible in cost. On some things "If it ain't broke don't fix it." But several years ago when I first was looking at a Corvette engine we were putting into a Street Rod it sure got me excited.

Jack...
I know it`s too late now but when the starter on my Kannon took a dump I found one on e-bay for 120.00. If I remember right I searched under chevrolet starter as my keyword. might enter powermaster as your search. Anyway... I thought I got a good deal. It was chrome and worked flawlessly. There were several to choose from and the supplier lists them there all the time. Just thought I would pass it along.

Thanks for the info . Tom, but I should recieve the POWERMASTER in a couple of weeks . I like the POWERMASTER because I believe it is a much better statrter than the stock starter that Came on the 2000 Boss . I believe it is sealed much better and is water resistant . When I mount it I'll have my stock starter for a spare if I ever need it . I already replaced my stock alternator with a POWERMASTER . Now I'm going to replace my water pump with the new pump that Neil has been experimenting with and I think I will have everything bullet proofed.

That new pump sounds interesting. I`ve heard a little about the advantages of a reverse flow cooling system. Should be a big plus for the boss.
