One tough impeller

[hanzj]

Some one was asking me about these but I forget who it was....

Anyhow these impellers are good. They claim to be able to run dry for 15 but I won't be testing it.

Good info! Thanks!

I installed a Globe this year. When I change it next year I'll post pictures of what it looks like after a year of service.

Awsome link hanzj! Their site only shows one model for Mercruiser inboards #2000. I know there are various models, sometimes within the same year. I'll have to check it out further.

Well, your impeller will be good, but what about running your engine for 15 minutes without any water? Doesn't sound very wise to me to have a $30 part that is good, but to overheat and blow a $5000 engine???? I'd be wary of using something like this.

[delongheavyhaul]

IM WITH YOU TIGEAZ!

[scootc]

I agree. I don't know why anyone would run without at least a fake-a-lake hooked up. I went with the Globe with the idea it might last a little longer.

[smendez]

I'm concerned about the 15 minute run dry claim. That's great. However, does the impeller stand up to a tough winter in Wisconsin without breaking apart in the spring? I read the problem with most impellers is not that owners run them dry, it's the winter storage that kills them.

[raythompson]

That is also my understanding about the impellers. The impellers get dry and take a set. When they are used the blades break or do not make good seal against the pump wall. Use is not the cause of the demise of the impellers, but non-use.

I would still replace the impeller each year at the start of the season when the oil is changed. A critical component, that is not that expensive, should not be overlooked.

[TeamAllen]

I think the major reason the impeller is better, is the properties it is made out of. It states, "made of elastomer compounds." I don't think that it can run dry for 15 minutes is it's main attribute. That just gets your attention to show how tough and durable it is. When I remove my standard rubber one it has small cracks around the vanes. Mostly because the rubber gets dry and brittle during the winter storage.

I would imagine this composite impeller does increase the service life. It should be more durable and flexible.

If you ever do any suspension work on your vehicles, you probably used polyurethane bushings instead of the standard rubber ones. They are just superior in performance and longevity.
It is always wise to inspect and monitor it as Ray does each year, regardless of which one you use.

That's my .02

anyone out there have the site to order from mercruiser on parts number? I need a new impeller;)

[TeamAllen]

Try this one.

Merc. Parts Express (http://www.mercurypartsexpress.com/PartsExpress/ProductSelection/ServiceParts/sphome.asp?CID=)

[Domsz06]

Thanks. I used that one and it is charging me more then the dealer does.:(

there was one site that I thought I found on here last year that was really cheap compared to the dealer. I did a search and didn't come up with anything:(

[TeamAllen]

I see. This is all I've got.

http://www.stemtostern.com/

[Domsz06]

wow, wish I ordered more parts, stem to stearn has it for 14 dollars off.

[TeamAllen]

If you know the part number you might try entering it in google's price search option.

Froogle (http://www.froogle.com)

[Domsz06]

Ok, not to sound dumb, but I don't get how to order it off of Froogle?

they have it, it's cheap, and when I click on the link there is no way to really order it. Am I just stupid?

Part number is 47-862232A 2

[TeamAllen]

You don't really order off Froogle. It is just a search engine for prices. Try this link.

Diversified-marine (http://www.prestostore.com/catalog.php/pmcparts/pd70582)

[Domsz06]

Thanks you rock!!

[TeamAllen]

Thanks domslude. Glad I could help. Did you end up with Diversified-Marine?

[steves1967]

Ok this might be a sillyquestion- but where is the impeller? I know where it was in my old outdrive boat but not on my 05 22v. Anybody tell me where it is? Thanks!

[Domsz06]

I can't tell you exactly since I don't have a v-drive, but if you follow where the water enters your boat, then follow the tube up to the engine, you should see where your sea water pump is, then in that is where the impeller is.


TeamAllen

Yes I ordered it from diversified, Mike there is a GREAT guy.

I am the Product Manager for Globe Marine Products Division. Your logic is backwards. The rationale and the execution of this principle is as follows, and is a two part paradigm

1- by the time you run dry x minutes, you ought to have warning from either an audible or your guage or both. At which point you will shut off the engine. You ought not be able to go the full 15 minutes, with out some other warning being sounded long before that. THe Globe advaantage: YOu wount be pulling impeller pieces out of your engine, and when you rectify the situation, your impeller will continue functioning once flow is restored.

2- the 15 minute measure is a continuous measure, in practice this allows an almost infinite number of narrow dry running time slices without impeller destruction. This to include clogged intake, dry start and drop, loss of prime due to other exogenous factors.

The Run-Dry (r) impeller is proven 2-3 x more durable than the major impeller manufacturers, 2-3 x more abrasion resistant, and with similar or better flow degredation after set performance.


We suggest changing the impeller every year under heavy use or continual use in difficult water conditions.

Under normal usage one can comfortably change every 2 seasons.


Please fell free to contact me with any other issues and concerns.

Hey, how about posting a "How-To" on changing your impeller on a couple of the most popular Tige engines (someone did a poll recently)?

Having shredded a few impellers myself, I'm all for having a tougher one. Also, have you guys worked with the manufacturers on warranty? So, if I replace my impeller with one of yours, does that invalidate my extended warranty from Mercruiser?

[WHALER25]

I can't comment about the whys and wherefores of the impeller replacement procedure for your boat, and we do not work directly with the manufacturers.

I don't know what the length of your extended warranty is, but once the warranties are up, you can do as you wish.

If you are very concerned in this area, propriety demands that I tell you to use whatever product does not invalidate your warranty, as much as i would want to tell you to use ours. If the impeller has no impact on warranty, then please, by all means, USE GLOBE!

Hey guys, I'm on season #2 of my Globe and everything is still running cool! I have a replacement kit I keep in the front storage (just in case), but wanted to see how long the Globe will last. I'll pull it out at the end of this season (October) and post pictures.

[tobo57]

The globe impellers are a big improvement,I think. I ordered one and it looks as if they don't make one for the mercruiser starting in 02.If it can be modified I'd like to know how.
