Ballast pump impeller?

[talltigeguy]

I did. When I go to empty the tank, only a small stream comes out, so if it's filling as slow as its empty (ing), I'm thinking impellor.

That seems wierd. The pump that empties the tank is different than the one that fills it. You have something else going on if that is true. I would look for a kinked hose as well.

I suppose if the overflow hose were blocked, it might not let water into the tank very easily, and interfere with the emptying.

The impeller on those pumps are incredibly reliable. I have gotten home from the lake and realized that I left the dishcarge pump on...running dry for about 40 minutes. Never a problem. I think I heard of Dom or was it nickypoo who left his running for a week without ruining it. It is made of hard plastic, and does not create much friction in the housing.

Goes back to the vapor lock issue that Matt brought up...

I don't think so, if what he said is correct. One pump is located on the manifold and one at the bottom of the hard tank. How do you decrease the effectiveness of both at the same time? Vapor lock does not explain the discharge pump not putting out.

He is having a filling and emptying problem. Post #1 and #3 state that. Now, if what you are saying it true then, he has two ballast pumps and both are not functioning correctly. This makes me think he only has one ballast pump to fill and empty not two.

You are corredt in BOTH pumps were not functioning properly, which led me to beleive a blockage some place. I just returned from my boat, and followed Matt Garcias suggestion in regards to the "Vapor Lock" issue. Guess what... I took off the heads of both pumps, and let it drain for about 5 seconds, re attached them and BAMM! As good as new again. I've never heard of vapor lock in a water line before, but kudos to Matt, and thanks to all of you for your ideas.

This type of thing is exactly what makes this website, and fellow Tige' owners so great to visit with. You guys probably saved me a $300.00 bill from my local shop for a 15 second fix.

Thanks again!!

Vapor lock in both pumps...that is lousy. So it sounds like you have 8 pumps and the two of them on the same tank got hit at the same time. With that kind of luck, you better go get a lottery ticket, today!

I understand how it happens on the intake pump, but I would assume it is impossible on the discharge pump. How is the discharge pump mounted? I would think that the pressure from the full tank would be enough to push any air up and out the dicharge hose.

I'm with u on this one to

Thanks but Matt was the one with the solution to the problem. I was tryin to help troubleshoot.

Awesome, glad you got it to work!

Also this is not just a Tige issue. In fact its an issue in almost every boat manufacturer that has integrated ballast. I cant tell you how often I have seen this or have heard about it. Just last week I was on a friends 05 24 SSV Supra and he had the same issue.

my factory system fills up great the first time out from the long week but when i fill a second time that afternoon or next day they wont fill, i agree with matt on the vapor locking, so what i do is put the boat in reverse for a few minutes, i call it quick injection, fill time cut in half

Thats another fix too. That is what Andrew from Tige recommended to me as well and it works most of the time. I have found that if you fill the front sack first then the rear you have less complications. Seems that trying to fill them all at once causes air/water turbulence in the pumps.

None of my pumps on my Rival install have ever done that, on the manifold or discharge. With a scoop on the intake under the boat, I can see why it will virtually never happen on the intake pumps.

I still don't quite understand how it happens on the discharge pumps. The pressure on the pump, if it is mounted correctly, will always get the air out. Is the pump mounted on top of the tank with a tube going to the bottom of the tank?

The discharge pump is located at the base of the tank near the rear. I'm currently replacing my stock ballast on the Port side with a custom Enzo sack by "Fly High". I'm going to continue using the stock pumps and such. I'll keep you posted on how it goes.

Ya definitely keep us posted b/c I have been seriously considering doing something like this, only on the starboard side. I'd like to know how it goes!
