Well, in an effort to get my ballast to fill faster and be more reliable, I decided to polish the insides of each of my ballast pumps and the covers. Also, installed the new "green" impellers I got from my dealer. I now have a set of Yellow, Black and Green impellers. I bought the yellow ones at the begining of last year but they would not create enough of a pressure head to pull water thru the system. I went back to the black ones and had some success. However, I burned two of my black one up by the end of the year so I decided to replace them with the new green impellers. I'll let everyone know how they work.

Let us know if it helps...What is the story behind the green impellers? I know they came out with theyellow ones...but not seen the green ones until now.

Can you or anyone get me the actual Jabsco p/n for the yellow impellers or green impellers?

I was just at my dealer and he told me the latest impellers were yellow. Said the green ones were from another manufacture. Bought 3 of the yellow ones. Hope I didn't just buy old sotck. Maybe Eric or another dealer can chime in and give us the real deal.

The green impellers are form, fit identical to my black and yellow impellers. As you can see, they fit just like the others. I did notice they were a little more rigid than the yellow ones but softer than the black ones. We'll see how they work.

there was some info on the green impellors in a 'ballast leak down' thread. Some say the green impellers are the latest and will help with the leak down problem. Others say the impellers are older... Sometimes it's hard to get the real skinny... Your experience will be good info. Nice job on the polishing!

What is the difference between the green and yellow? Why does the MTS need a different impeller, it uses the same jabsco ballast pump, right? If the green impellers keep water from flowing out when pump is off, they may be a good choice for all ballast pumps. Would someone try them in their wakeboard boat and let me know if they are any good. lol. Whats the price difference between the yellow and green? so so many questions.

Yes let us know how well the green ones perform.

The yellow ones for my KGB tank take forever to fill/empty, so I went back to the black one just for that pump/tank. I'd love to try the green ones.

Also, what did you use to polish your pumps with?

I've got 3 brand new yellow impellers that I've had for a year. Tried them once and was not impressed. I bought the green one - which definately have a higher durometer than the yellow ones but not quite as high as the black ones. I'll sell you the yellow impellers if you want them.

Update - it's still raining in Seattle and therefore have not had the boat in the water. It's elevated about 3 feet above the water on it's lift. Spring always sucks around here. Hopefully I'll get the boat out on Saturday or Sunday in between my son's baseball game, football tryouts and my daughter's tennis practice.

Thankfully there is no sports during the summer. Everything ends mid June and it's time to hit the water and teach the kids (mine are ages 9 and 7) to ski and wakeboard. We'll also get some tubing in also. Gotta luv tubing behind the X-30 with an L-18 engine. Those little guys can barely hang on.

I have an '09 X2 (KGB?), dealer replaced the yellow impellers with the green to fix the siphoning problem. I have been out twice this year, no siphoning and seems to fill and drain much faster! Dealer mentiond the green ones were slightly taller??? Can't confirm since I did not complete the switch. I am keeping the yellow ones for back up!;) So far so good!

prostar205

Ok, I finally made it out yesterday and filled the ballast using the new green impellers with my polished insides of my pumps. Everything worked great. I will keep my black impellers for backups.

I believe MTS stands for MasterCraft Training System. It is a hard tank that hold apprximately 180lbs of water. It is located under the bow of PS190s to simulate a person sitting in the observers seat to balance the boat out during a ski run.

Hey all,

I installed the green impellers late last summer (got them from waterskis.com), to help with my fill/empty times and stop the siphoning. I had the yellow impellers in the pump and there is a clear difference in performance. The green are a bit more rigid and seem to almost completely stop the siphoning.

It will be interesting to see how long they last. Even though we live in Seattle, we ride year 'round and put between 150 and 200 hours on the boat each year.

The green impellers last longer than either the black (because they have a lower coefficient of friction so they don't get as warm) or the yellow (because the material is more dense, so it doesn't wear as fast).

We have customers that have over 200 hours on their green impellers with no changes in performance.

UPDATE - finally got the boat out for some surfing for the 1st time this year (11U All-Star Baseball has been consuming my weekday evenings and weekends).

The new ballast configuration that has separate inlets & outlets for each ballast puppy is working great. I can now fill 2,000 lbs of ballast in slightly less than 10 minutes.

Thanks to Jason at Wakemakers for the help over the weekend.

When I disassembled the impeller body from the motor of the pump I reinstalled them backwards so fill is empty and empty is fill. Works great now.

Accident, to make hose routing easier? We regularly remove the pump head during installation to facilitate clearance issues.

prostar205
08-04-2011, 12:26 PM

Jason is correct. I also disassembled the pump housings from the motor to help during the polishing process. When the pump housing is removed from the motor, the impeller's shaft stays with motor and the housing can be polished easier.

prostar205
03-11-2012, 08:31 PM
This winter's polishing is now complete. This is probably the best these have looked since I started completely removing and disassembling the pumps from the boat each fall. My ballast system now can fill 2,000 lbs. in about 7 minutes and the draining process is even faster.

Here are some pics.

Do you see any decrease in fill time from polishing the pumps?

prostar205
03-13-2012, 06:15 PM
Do you see any decrease in fill time from polishing the pumps?

Completely the opposite. The fill times are improved by about 10-15%. The impellers never get stuck when trying to reverse the direction. I got rid of the 2002 manifold design completely last winter and drilled 2 additional holes in the bottom of my boat. Now, each pump is directly fed by a 1" line.

JRW160
03-13-2012, 09:16 PM
I would consider decreased fill time and improvement ;) I haven't had any trouble with reversing directions since swapping to green impellers. Do you have an estimate of the fill rates you are getting?

Did you have to install any check valves when you removed the manifold?

Agreed. I typed my post too quickly. I saw my fill times go from 45 minutes (yes, 45 minutes) to just north of 7 minutes. This was not all becuase of the polished pump insides. As I mentioned, I completely overhauled the ballast system with the help of Jason from Wakemakers. I got rid of the manifold and am direct feeding all 3 pumps. I also removed any and all 1-way valves allowing the water to fill and drain thru the same hose thru the bottom of the boat. Works great.

prostar205
03-14-2012, 02:45 AM

No check valves at all. I fill and drain using the same 1" hose that goes from the thru-hull fitting on the bottom of the boat to each pump.

JRW160
03-14-2012, 12:27 PM
Are you filling 750s in the back?

My fill times were around 30 minutes last year. I put in two more thru hull fittings for the rear pumps. I left the pump for the front sac on the stock manifold, so it will still drain out the sides of the boat.

prostar205
03-14-2012, 12:31 PM
Yes, the 750s are in the rear lockers. I removed the hard tanks many years ago.

The manifold was/is the weak link in the ballast design of my year boat. It just could not provide enough water to run even 2 pumps at the same time. Getting rid of that mess really cleaned up the entire system. Now, the system is really simple - fill and drain each bag independently and no check valves. I'd never go back to the way it was. All 3 of my bags are plumbed the same way.

So your 750s fill in 7 minutes? Do you have 1" all the way to the bag? I have 1" from the thru hull to the pumps and 3/4" from the pumps to the bag. I'm trying to figure out if this is worth the time. I doubt it will happen this year, but maybe next winter.

Yes, my entire system is plumbed with 1" hose - Starboard (750 lbs), Port (750 lbs) and KGB (500 lbs).

I doubt you'd gain much. It's pretty normal for the inlet side of the pump to be larger diameter than the output side since as pressure goes up the volume of water that can be moved through a given size of hose increases. You'd probably see a slight improvement but not enough to justify the hose expense or the time required to install it. If you had a larger inlet then you'd likely see greater benefits using 1" hose.

The only hose that is under the floor is the one going to the front KGB. For that I just threaded the new hose under the floor. It was pretty simple.

03-16-2012, 09:54 PM
My 750s fill in 8 minutes right now. Speeding them up wouldn't be worth the effort. The ski locker and bow sac are on the same pump, so I would have to wait on those to fill anyway.

It depends on the boat. I pulled up the floor in mine and had easy access to the hose for the Kgb. In a newer boat where the floor doesn't come up, i would imagine it's much more difficult.

I would imagine so, on my 06 X30 they're bolted to the transome, behind the muffler. Once you pull that panel off the back you'll see them. It's no big deal to access them, it's tight but not that bad..

How long before the ballast impellers need to be changed? 09 X2 with 235 hrs. Ballast pumps are working fine and have not noticed any decrease in performance. Still have the OEM impellers (don't know if they are black, yellow or green though, never opened up the pumps).

When I do change are the green impellers still the ones to replace with?

I did a complete tear down of my pumps today and got them all working again but the bearings are still a little rough so it makes them a little noisy. How did you get those bearings off to change them out? I did not want to hit them too hard thinking that I may make something worse?

I consider this routine maintenance about twice per year, it never hurts. Also, use white lithium grease on the o-rings to get a better seal.
