Title: input shaft seal? leak
Post by: TnT Customs on January 23, 2012, 08:47:56 PM
OK so my setup:
Jacuzzi wj? With American Turbine energizer kit

And when i'm sitting still on the water I can see a steady stream of water leaking from the jet drive around the input shaft. What's the best fix? Tired of turning on the bilge pump every 20 minutes

Rope seal.

Try tightening the packing gland nuts in small 1/4 turn increments. It's supposed to leak a little otherwise the friction of that shaft spinning in the seal will burn the seal.

Jacuzzi doesn't use a rope packing or mechanical seal either in original or in "energizer" form, it employs to Clipper seals in behind the main bearing to seal the suction from atmosphere as well as to keep water from the boat and the bearing,  if water is weeping from the weep hole on the bottom of the seal carrier its because the seal (or seals) are fowled or damaged There no adjustment or simple fix the pump shaft needs to come out for repairs call me if I can help or I'll talk to you next time i'm in MB ..
