no need to get them all one way just lube install and when started they will alighn there self

Not to sound knowledgable, but when twisting it in they all go the same way. If it fits otherwise replace housing.
I have found that needs to be done every other time, grooves is a bad thing. Buy the whole kit, replace often. Why not.
Piece of cake and piece of mind.

I have two seawater pumps that use an impeller that is 5" long (and 3 3/4" diameter and 12 vanes). Sometimes they go in with the tips all facing one direction, some times they want to go in with them all facing the "wrong" direction, sometimes they go in with the tips "parted down the middle" to opposite directions.

These boogers are stubborn enough that whatever way they get on the keyed shaft and start in - that is the way they go in.

The first 1/8 revolution of the impeller orients the tips properly with no harm to the impeller so it is a nonissue as far as I'm concerned.

Reed, nothing wrong with KY drying on the impeller. Same deal as dried soap.

I'm not worried about the ky drying.. just not providing enough lubrication if the pump is to sit for months before running... that's all... once the pump has been run.. there is always some water left in the vanes and passages...
