raw water impeller change

i have been lurking for a while and like to add this.
i use lanolin, i buy it by the pound from cosmetic supply. cheap and coat the surfaces for the gasket etc, No galvanic anthing.'
its marv, stuff. the pure anyhdrous, without water, lanolin is a dielectric, insulates dissimilar metals., wont wash off with water, and i find a lot of uses on the boat for it/
its a great drilling lubricant when drilling aluminum, and the stainless steel screws coated with it dont promote a response.

Yes, and they have an improved, additive containing version, called LanoCote, sold by Forespar.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

This sounds like a great idea to me. Probably a lot cheaper than Lanocote, too. I would wonder just how different plain old lanolin and Lanocote are.

I have been using biodegradable dishwashing liquid to lube my raw water impeller and pump (Yanmar 2GM20F) when changing the impeller.

it was about 7.$ a lb. with postage from the place in Oregon, I bought three lbs, cant stop using it on darn near everything, including holding ss screws onto the driver in odd places vs gum/ ive the tool for slotted head but not cruciate or phillips.
when i did a search on it it goes back to biblical times for use around water. if anyone wants the address, of the supplier, ill try to post it. no affiliation etc etc.

Lanocote is great stuff. I'm in the process of slowly redoing the entire mast. Wherever I find a stainless steel fastener going into aluminum, I remove it and coat with lanocote. I hate the corrosion bubbles that form under the mast paint around SS screws!!! Having said that, A can of lanocote goes a LONG way!!!!

Cheers!

I've heard people recommend Dow Corning 111 (Mfg website). Anyone else use this on their impellers?
