Hey guys,
Whats the best thing to lube new rubber sea pump impellers with prior to install? Soap?
Thanks

Dish soap works fine.

A ty-wrap to roll the vanes over so it goes in easier. No lube necessary.

I was worried about initial start up, not getting it in the housing. The soap doesn't dry out and stick?
OK, thanks guys !

White lithium grease.

I use vaseline

I just looked in Mercruiser manual. They say dish soap.
Thanks guys for the input. Just got one down!

Some of us use Dawn for flushing the engines after salt water use. I use it for SWP assembly too.

A zip-tie around the veins sinched down a bit works awesome to get the impeller started into the pump. Get it about 1/2 way in and snip the ziptie off. Then rotate the impeller the rest of the way in.

I use Mercury 2-4-C grease, dish soap will work great if you are going to run the boat right away, if it may sit a couple of weeks before running the grease will not dry out.

KY jelly ,, it really works..
