MaxiJet sureflow 1600gph?

How old was the Maxijet? I've only seen this twice myself and both times due to the really old maxijet pumps.
I think this is an issue due to the age of the pump where the plastic end is worn out and made brittle.
That or a build quality issue of the MJ pump itself.
I don't see how the GSII mod or any mod could have caused that by themselves. I think if this was to happen it would happen with the stock MJ anyway sans mod.

Well I found a lot of people that have had the same issue and they all say that it was because of the wavemaker. My olds pump are still running, the newest one (about 7 months old) Was the one that got the hole.
dhnguyen, Do you use yours on a wavemaker?
Can I fix the one with the hole? or should I trash it?
Thanks again

Does anyone else think that these MJ pumps were not made to have the extra pressure induced by the proprellor, and this may be why the hole is being made in some of the older maxijets that may already have brittle plastic?
Honestly I don't see how that can be. I have had tons of mods running on wave timers and have never seen this happening except for the 2 instances where the MJ pumps themselves were very old and brittle. Unless there is something here on your kit that I'm unaware of, any pics of your end caps and shaft?

Could be, the prop does push back fairly hard.
You could fix it, the crucial issue will be getting the impeller centered (much like the DIY maxi mods). If you have the pieces it should be real easy to epoxy it back into place. Heck you could resin cast the entire back & put the cover back on = should never break.

I had the back break on one of my modded MJs. I was using the DUMAS 3004 prop on an older MJ1200. After I dug the pieces out from behind the rock, I superglued the piece back on then covered it with epoxy. Its been running fine with standard impellar haven't tried a mod on it since I fixed it.

Got rid of rattling/vibration w/ sureflow 1600 on Maxi 1200
Got rid of rattling/vibration w/ sureflow 1600 on Maxi 1200
A couple of weeks ago, I modded a Maxi 1200 that I had with a Sureflow 1600 kit ( stock kit ). I really like the flow it produces but I had a vibration and rather frequent rattling sound that was becoming annoying for me. Previous posts in this thread said Sureflow ( Algae Free ) would take care of the problem but I decided to try an idea that was mentioned somewhere in this lengthy thread.
All I did was change both of the black/red end caps that go on the end of the rod with the ones that were originally on the Maxi jet 1200 impeller prior to adding the Sureflow kit. They seem to be made of a harder material than the ones that come with the mod kit.
After changing the end caps, the Sureflow 1600 has been running completely silent on the Maxi jet 1200 without the slightest hum, vibration, or rattle. The harder caps must hold the propeller straight and balanced compared to the softer caps that allow some movement ??
Anyway, just wanted to share this in case some of you are having the same noise issue with yours.

The GS2 wasn't making any noise the first night but had vibration/rattling noise the second night but after a week it's almost not noticeable.

Hmmm so the end caps on the Sureflow aren't the stock MJ end caps? I'll have to take mine apart and look and compare. If the end caps on the Sureflow are smaller and allowed to rotate, I can see how this thing could eventually drill it way through the bottom of the MJ pump.

Yeah, they are different. The ones that come with the Sureflow kit are softer. Just squeeze it and compare it to the ones that come with the Maxi-jet. You will see the difference. I wonder why they are different ?
I just confirmed it. They ARE different than the stock MJ end caps. :eek1: WHY is a very good question.
But now that I inspected the end caps closer I can see how noise can be an issue as well as the end cap having the potential to drill it way through the MJ pump. This thing is too loosely fitting the MJ pump which would mean it has the potential to spin with the shaft as well turning itself into a drill bit if you will Hmmm....
The obvious and easy fix is to replace those Sureflow end caps with the original MJ ones.
