Stupid aerator pump

[buckwhisperer]

Put in an "attwood tsunami" to replace my old "rule", both rated at 500gph but new one won't make it to livewell. Its approximately 2' of head, same as before, i've put hose up, down, every possible way and finally got tired of not knowing what was happening i put on a clear tube and can see water is getting to about 2" from elbow and stopping. Funny thing is that if I quickly remove hose from pump, water squirts out, and then quickly replace hose it will start working fine. Any thoughts? Again, hose has been I'm every direction.

I have had a few where after a pump swap (to Tsunami) the new pump didn't want to prime.  I have tried altering the pump angle (when you can. Usually you can't, especially if the pump is attached to the fill/drain valve) but it didn't help.  

The answer, as Flintstone as this sounds, is to close the valve and turn the pump on as you are backing up in reverse until it starts to pump.  Do it as you are backing off the trailer. After doing that it will pump fine all day until you trailer the boat again, even if you open the valve and drain the livewell. Apparently it is just a small bubble of air that gets trapped and prevents the pump from developing its pressure.  

If having to do that annoys you then ditch the Tsunami and go back to the Rule.   I like the Tsunami, they are quiet and run noticably cooler than the others...but they don't prime as easily.   Another plus is that I have yet to see a Tsunami freeze and bust.

Thanks wrench, I'll try it.
