So there are lots of threads on this topic and many opinions but I am ready to replace my
impellers in my 2002 X-10 ballast pumps. I have the green ones everyone raved about but I found they work great in one direction but not the other? The local dealer is saying the jabsco rep says to use the black ones as they dont heat up the pumps like the green ones do?? So who is using what and has the best success and why...........Thanks

Intresting...

I found just the oppisite.
The green ones last longer,but there fill rate is slower.The black ones fill quickly,but don't last.
I have the green in my pumps and mine seem to work fine in both directions.

The black ones are way too stiff. I had a black one in one of my pumps, and it would not reverse directions most of the time. I got sick of pulling that impeller to fill/drain and switched the green ones. My other 2 pumps had yellow ones and they seemed ok, but I think the green seem to work better overall.

Just installed green ones this Saturday and they filled fast. When I emptied they sucked the bags tight like a vacuum sealed bag.

Can the "green ones" be purchased online somewhere?

Wakemakers.com seems to have them .....

How hard is it to change out the impeller?

Just saw the you tube on it. Cake. Cant believe the dealer quoted 11/2 hour labor.

Once you get access to the pumps it takes about 3 minutes per pump

Another question. is it imperative to run the engine RPM at 1500 minimum while filling and emptying the Jabsco pumps?

Hmmmm...they are electric pumps. Maybe to generate higher current to the battery to cover the draw...??

Well ... It helps with the load on the battery, and their rpms for optimum flow ....... They run a finite cycle since they have timers ..... At 1400 rpm those things are good .... Also the ballast gauge calibration may measure the amp change when empty during the empty cycle. Still learning about this myself.

i have had all 3 colors in my 02 x star. the black ones worked good, except once in a while the pump would get stuck in one direction ( because they are the stiffest) the yellow ones filled slower, but worked flawlessly, i was sold on the green ones becuase they are supposed to fill like the black ones, and last as long as the yellow ones.... i didn't really notice a difference in fill time between the yellow and green ones.... not really worth replacing yellow w green if they don't need to be.... i have 3 yellow ones i would sell to someone who is in need of them? used 1 season.

What is the reason for the 1500 rpm. Sorta a pain??

Alternators do not charge at idle speeds - raise the RPM's to bring up system voltage slightly from battery's typical 12v to maybe 13.5v or 14v is the theory. That being said, I don't do it to fill and I will drain while underway, if possible so I guess in theory I do it then, but not so the RPMs are up, just so I don't have to sit there and wait. I also think the flow over an inlet might help with the suction or the bow up attitude help to get the water out - especially out of the bow tank,

anyone know how hard it is to get to the pump on the kgb on a 07 x2. i have replaced the two rear impeller's with the green ones but have not the front.

thanks.

KGB pump is the easiest to get to on the X2, it is in the bilge bay next to the trany, starboard side. Pull your rear seats, and transmission bay access panel, facing the back of your boat, it will be on your left side.

matt, thank you. seems that it keeps filling the tank without the pump on.

I have filled and drained without the engine running with no issues, but only do one at a time. Maybe if I were to do more than one at a time, it would help to have the engine running............

This is a problem that I had and was caused by the yellow impellers. By switching to the green ones, I did not have that problem again.

Same here, had the yellow ones, was also having a siphoning issue, switched to green under warranty:D and all is good, same green impellers and about 300 hours on the boat and we fill 400's in the rears via overflow and they are still going strong. I think a testament to running the engine at 1500 RPM's, keeps the pumps spinning at optimum levels and does not wear on the impellers.

I said it before and will say it again, other than an occasional pump time out follow this rule and you will not have pump problems...

Fill at 1500 when standing still - Empty in motion plowing at 1500. I run all 3 pumps at the same time also.

I'm not sure how the tank could fill without the pump on. The pumps are well above the water level, at least in my X2...........:confused:

I dont think it could siphon past the impeller.

Mattscraft,

Do you fill and empty all 3 at a time, or just empty all 3 at once whilst underway. I've always been a little hesitant to do all of them at once.

thanks

Fill and empty all 3 at the same time, of course the KGB fills first because I have the bags on the overflows in the rears. As soon as the KGB spits out the side, shut it down. I fill my bags to about 80%,

matt, you were correct and that pump is by far was very easy to find. need to order a couple of green impellers and have a back up.

thanks again.

I was told by Jabsco to run the engine at 1100 rpm. They do fill faster which is important when you run extra fat sacks else you time out.
