Tsunami Pump Intake Fittings - Help!

I tried searching for this unsuccessfully...I only found references to Tsunamis being used with big manifolds....

Anybody know off hand if the Tsunami pump is a direct replacement for the standard threads found on like a Rule 1100 GPH pump? For example, on my VLX, can the Tsunami be threaded into the thru-hull fitting in my ski locker where there is currently a stock Rule pump?

Thanks,

Danny
