G23 Impeller Direction

[cstiles]

Hi guys,


I just did something really boneheaded. I've been helping my friend winterize his G23, and to get the hoses off of the raw water pump, I had to remove the pulley and expose the impeller. After I pulled the hoses and blew the water out, I thought I'd check the impeller to see how it's holding up (also heard that it's smart to let the impeller "rest" over winter). I'm sure you've guessed it by now - I pulled the impeller without making note of what direction the fins face! So. Stupid.

Anyway, now I need to launch an investigation on the rotation direction of the PCM ZR450, what direction the fins need to face to pump, etc. Unless, one of you may have happened to take a picture of their impeller in the pump, or has another thought that can help me out.

Thanks!

Two things. One, I do take mine out over the winter....Two, my research and I know some sources say one thing and some say the other...But I have read and I agree, that it does not matter, as soon as you turn over the engine - long before it starts, the blades will flop over to the correct side.

Your motor spins in a left hand direction (looking from the rear of motor), that should help you determine which way your pulleys/impeller will be going.
However, agree with Scott it really does not matter. You could always put a bit of dishwashing liquid on it at re-install and it will definitely make it spin easier initially.
Personally think impeller should come out every fall if nothing else to be inspected, whether or not leaving it rest will extend it's life, who knows, probably does so I have always done it.
