Ever noticed how a can of lithium spray grease looks very like a can of fogging oil?

So I'm winterising the boat / trailer etc. Spraying the carbs and cylinders with what I thought was fogging oil and to my horror, discovered I had picked up a can of lithium spray grease instead....red straw and everything....after I had sprayed all three carbs...and all three cylinders. Went back round and sprayed all carbs (in WOT position) and cylinders with fogging oil in the hope that this will thin the grease... Where the boat is kept (Arran) facilities are limited so re-winterising would be a PITA - very weather dependent - and I can't see that the spray grease will do any harm, apart from to the environment when I re-start in the Spring! Any opinions?

I think you might have fun getting it started if you leave that in there all winter.

Yes, I have a funny / terrible feeling you are right. It's going to be a few weeks before I am back at the boat (I don't live on Arran) so I guess I can have the fun then (weather permitting) or in a few months time...The concern would be if anything would actually damage any components in which case I would make a special trip but seeing as few, if any, people will have been as stupid as I have, I suspect I am in uncharted territory so I am just going to have to wait and see. My hypothesis is that once petrol gets flowing through the carbs, it will thin and remove any grease deposits. Oh please let me be right!!

Your hypothesis is reasonable - but it strikes me that there are a couple of important points:

(1) It will only flow through the carbs is you can get the engine running, if the carbs are clogged at all you won't get a flow,
(2) Not sure about Li grease but some greases seem to set a bit once they are exposed to air (or perhaps when some volatile component evaporates) - if it sets it will be harder to clean off.

Nos and Poly, as two of the most esteemed ribnetters, I would be a fool to ignore your, much appreciated, advice. The boat is going to lie for at least a week so I'll have a go at starting it but I fear I am screwed - a carb stripping and cleaning session looms. Nightmare.

Not used the spray stuff but as was said earlier in the thread i have found that lithium grease when left tends to get a crust or skin when left exposed to air for long periods.

Well Nos is quite technically competent whereas I'm the sort of idiot that would spray grease in the carbs!

I don't think its going to be a disaster - but the quicker you can get them rinsed the better. I wonder if others think it might be worth spraying something like break disk cleaner in there and then rinsing with fresh fuel, before you try to crank it up again?

I would spray carb cleaner onto a rag and try to wipe out as much as possible, utilizing a screw driver to gently push the rag in deeper. Then spray pretty heavy into the carbs, and again wipe it out. Start the engine and let it run for a couple of minutes, then spray the carb cleaner in with it running, but only a little at a time in each carb. You don't want to wash the rings, nor cause it to stall.

Fog the motor and call it a day. I doubt the grease will harm anything at all.
