Replacing impellers

[Seastoke]

I was just reading , on the sealine forum, and the guy says he plasters the impeller and the strainer with fairy . He says it helps with the impeller does not stick , also you see the bubbles coming out at the rear so you know it’s pumping . It maybe an old tip.

Any lubricant to assist getting the impeller in with minimum effort, washing up liquid,even a dab of grease or KY will do the the job.

If you have bubbles coming out of the rear, you probably need to see a doctor.

The lube, that comes with impeller kits is glycerin, but any grease is better than no grease.

And it doesn't matter if you get the vanes pointing the right way when fitting - the moment it turns they'll shift if needed.

A little entertainment for you:

Just to add....
When installing your new impeller, get a cotton bud and smear it with grease. Use that to rub the female (metal) splines (that mates to the shaft) of the impeller with grease... put most of it on the inside (ie. engine side) of the impeller as most of it will push out anyway.

And yes, rub the outer side of the vanes with fairy washing up liquid, goes in much easier.

I forked out for the 'impeller removal tool' (basically a bolt within a bolt) that you can thread into the genuine impellers but on the KAD300, the shaft is so long that it covers the threads to no good to me. Instead, I use a Knipex Pliers Wrench and pull straight out (I see some clowns 'wiggling'.... what are they expecting apart from a damaged shaft/seals)

I use fairy liquid each year when the impeller goes in. Always works a treat.

I found the same as did a friend with AD41's with so it must be common on KAD and AD engines.

Ask your daughter

Or your boyfriend

..or, rather, common on the pump fitted to these - and therefore other engines with the same pump (might be Johnson F7B-9)

Or your boyfriend

Stingo told me he is not gay but his boyfriend is.

Yes I expect they all have the same pump.
In my case the brass cover plates are Volvo Penta branded but obviously the pumps are not made by Volvo Penta just like most of the other engine ancillaries

Being trans he tends to hedge her bets

..on a related note: should I be concerned by the different Impellors, some with a rubber end cap and some without? Both apparently VP parts for the belt-driven pump on my MD22p.

What a weird thread. Not really your finest hours.

I only deviate when peeps are rude.

Anybody been rude? So far I have just seen some harmless fun jokes.
But if I have hurt your feelings then one can only say sorry- for you.

Peeps can call me anything , but talking about my daughter is different .
