Impeller Question
 

Anyone here had any experience with Globe Impellers. They are supposed to be impregnated with oil and have the capability to run dry without damage. I couldn't tell you how long they can run dry. They are also supposed to hold up better against sand and the normal crap that eats impellers. Cost for a bravo/inboard setup is about $45.00 per impeller. Not much more that stock. I have heard the military uses them exclusively. I'm going to freshen mine this spring and wondering if it's worth the extra doe. Check them out at globerubberworks.com

Re: Impeller Question
 

Sounds great if true, they only have two mercruiser models the 1000 and 2000. I guess the 2000 is for the Bravo type inboard water pump.

Re: Impeller Question
 

Ya, that sounds right. I was told that Merc recently has changed the way the shaft engages the impeller. Old style uses a key way. New style uses a flat. Globe does not have the core for the flat yet. (Just more info to share that I have found.) As long as my cases look good, I will probably try these globe impellers. Somebody must have used them before.

Re: Impeller Question
 

I ran globe on the port engine against a stock impeller on the stbd. I dont ever run them dry but wanted to see how they did. I do have lots of sand in the water where I boat. The globe was weak and the outer edge of the vanes scored after one year and I replaced it. The stocker has 2 years now and will see one more.

WOW! That's not what I expected to here. Thanks F-31

Re: Impeller Question
 

I HAD A SIMILAR EXPERIENCE - DONT WASTE THE MONEY.

Re: Impeller Question
 

Here's a picture of a Globe Blue with approximately 25 hours of use.
I have put an additional 42 hours of run time on this impeller.
I am going to do some exploratory surgery to observe it's present condition.

Re: Impeller Question
 

I put one of the Globe impellors in a customers boat - bravo style pump 600Hp 502 mag. It's been about a year and so far no problems. He was constantly burning up impellors before (he is on a Hyrdahoist and would forget to turn on the water).

What bugs me about the Globe impellor is the sloppy fit on the pump shaft. Using the drive key they recommended (merc part #28-56662) it can rotate back and forth on the shaft too much.

What impressed me about the Globe company is that when I called to see if they had a key that fit better or if they were going to produce a better fitting hub (that didn't need a key), the President of the company called me back and spent about ten minutes with me on the phone.

Re: Impeller Question
 

I just bought two of them for my 38 Fountain. I change my impellers at the start of every season but by August two year in a row within weeks of each other I lost the Merc impellers. I boat in clean water so I figure it's because the X dimensions are so high that they burn up from dry running. Globe claims their impellers can run 15 minutes dry. I'll keep everyone informed as to their performance as the season progresses. I will say that they do fit a bit sloppy on the shaft as stated above however, I do not feel it will be an issue. Also as stated above, Globe is VERY helpful. I purchased mine from Boatfix.com and Defender.com also carries them.

Re: Impeller Question
 

RLW ... what GLOBE impeller # is that ... #2000??

Re: Impeller Question
 

While the Globe impellor may run dry longer, what about the stock housing? Does the impellor keep the housing from being ate up to from the dry friction?

Re: Impeller Question
 

Yes, it is a 2000.
Here are some pics of the same impeller pictured above with 67 hours of use. It has been in the boat for three years.
2003 = 25 hours (old blower motor)
2004 = 15 hours (new 540)
2005 = 27 hours (not quite as new 540)
Yeah, I know, I don't get out much.

Re: Impeller Question
 

Needless to say (and since I had it apart), I replaced the impeller with a new Globe Blue. The housing looked good and the wearplates were fine.
I am still using the old two piece style housing.

Re: Impeller Question
 

Thanks RLW ... I'll probably pick up a couple for spares and swap 'em in next time round :)

Did you actually need the key for these things??? I do fine with the Merc stuff and swapping them in and out without any problems or keys ... so ... Thanks for the info!

Re: Impeller Question
 

I use the key and so should you. I believe it was a Merc part #.
It moves axially on the shaft, but has no apparent effect on the wearplates.

Re: Impeller Question
 

I don't use the globes.

Re: Impeller Question
 

This is Matt Koenig, Product Manager, Marine Products Division, Globe Composite Solutions. We manufacture the Run Dry impeller.

Lets adress your issues.

The new 2001 is a 3/4 single flat drive. It will fit much better.
THe 1000 and 2000 are still available for the older styles
Some of these posts are from 5 or more years ago.
THere has been constant and consistent evolution of the formula over that time with new ownership in 2004, as well

Please email me directly with any issues and concerns, I may be able to make it worth your while!

Thanks for all your support of GLobe

We will be booth 5126 at FOrt Lauderdale and booth 2052 at IBEX. Also booth q43 at Miami in Feb.

Re: Impeller Question
 

Matt Koenig again.

Dave, I think the president of the company was me!

While i wish I was the pres, I am just the Head of the Marine Products division.

Glad it all worked out and thanks for the kind words

We are always looking to tweaking the product and sheepdogging it on the trail to perfection.

Re: Impeller Question
 

I'm going to Ibex this year.... I'll look for you. :D

Re: Impeller Question
 

I will sell 2 new globe impellers for 45.00 total, as I purchased them for a replacement, but I have the Jabsco pump replacements and they have 10 vanes per impeller for more flow and I dont want to lose that.

Re: Impeller Question
 

I was told that the Globe impellors blades lay over at high RPM and cavitate. I too have a sand issue and also have a Globe 2000 in the box that I will be running in a Bronze Jabsco Merc style pump.
I like the K. E. 2 stage style unit but it's pricey and aluminum and gets killed by the salt ... BBB

Re: Impeller Question
 

Are these availabel for a stock merc 525efi pump? If so, what part nuimber and where can i get them.

Re: Impeller Question
 

lets chat about your experiences.
