Anybody using a Shurflo Piranha ballast Pump?

[d_coyne1984]

I'm looking for a ballast pump for my new bags and I found the Piranha 1100GPH on Amazon for considerably cheaper that the Johnson or Jabsco pumps. It doesn't look as hardy, but if it works I think it will be fine for my needs. Anybody have any experience with these?

These are 2 different style pumps. These pumps have to mounted below the water line to start pumping, where the Johnson and the Jabsco pumps can be mounted in the engine compartment. The Johnson and the Jabsco are also impeller pumps which the impeller can be changed out when needed if fouled. I have a tsunami pump, that I used to use which is comparable to the piranha pump that you listed, and I haven't tried to take it apart so I do not know if it is serviceable or not?


If you want a throw over the side pump then the piranha or the tsunami pump is what you want. Hard plumbing, then I would try to get to below the water line or go with the Johnson pumps.

One last thing, the piranha and the tsunami pumps are not reversible, so that is 2 pumps per bag. One to empty and one to fill.

My first ballast setup had that one 260-300 GPM HF pump one there for all about one outing. took WAY to long to fill up. These are decent pumps for little stuff, but not for ballast.

I installed several tsunami pumps in by boat, similar design as pirahna. Link below to extensive thread and design information.

You time your system yet for fill/empty @dan144k ?

@jcyamaharider
Not timed yet. Picking up the boat this weekend and probably gonna do some testing on Rend lake. I will post times when I get the numbers.

@jcyamaharider
Rend lake 70 degree water temp

2) 550 lb rear bago 5 minute fill 5 minutes empty, both bags same time
1) ski locker bag 800 lbs 10 minutes, 10 minutes empty
That is filling all 3 at the same time with a common intake and 3) 1" seperate discharges

@d_coyne1984 sorry if we invading your thread.
