re-installation of impeller

when re-installing an impeller that has already been used, which way should the bent vanes go. I know i installed one backwards one time, and it wouldn't turn. trying to de-winterize for the weekend.

Impeller

It doesn't matter. As soon as you start the engine, the vanes will align themselves correctly.

cool, thanks!! When i did it before, i think the impeller had been in for a long time and had stiffened up. therefore, when i started the motor with them bent the wrong way, it gave too much resistance and didn't let the pump turn and realign them. this impeller is only 1/2 a season old.

Thanks!

Put it in just before you go to the water. Coat it in silicone grease or binding lube so it has some lubication while it turns over. I twisted the impeller clockwise to get the veins in the correct orientation.

I just use dish soap....Silicone grease can still break down the rubber, can't it?

Silicone grease will not break up or dry out black rubber. A oil base lubricant like WD-40 will in time break down rubber. Soap is fine also.

Think about a new impeller

A new impeller is cheap insurance. If a blade comes off the impeller, it travels through your cooling system until it reaches a place it can't transit and then it lodges. Yes, it can be acid boiled out, or blown out backwards, but do you really want to spend the time doing that instead of skiing?

Any impeller is slightly damaged by the puller when removing it. They are even more damaged by when screwdrivers and/or pliers are used to remove them. If your impeller is so old that the blades have taken a set, scrap it. They can be bought at an auto supply store for a lot less than the $40.00 the M/C dealers want. Auto parts price is $15.00 to $25.00. Get one at M/C then take it to your auto store and duplicate it.

Also, put on a new gasket with every new impeller. Don't forget the lube.

My impeller was new 2 months ago, took it out for winterization, but it back in when i decided to ski. and as far as damage with a puller, and '85 with a pcm requires no puller, or screwdriver for that matter. I lubed it up, and it turned the right way with no problems. I'm skiing tomorrow!!! SC weather is great!!

Impeller Backwards

You cannot put a impeller in backwards but... you can reinstall a waterpump housing the wrong way on a PCM motor. Mark the pump housing before you disassemble it. There is a small drain screw on the housing. Hope this helps

Do you have any idea what I need to tell the guy behind the counter at the auto-parts store? I just always assumed it was marine only, so I always get mine from skidim.
