Well I think I chose the worst day (Weather wise to do my winterisation). It was blowing a gale and raining like no ones business. But the temps are falling so decided to go for it.
I put the fuel treatment in 10 ltrs and tested my giggle syphon to put that fuel in the tank. It worked fine and confirmed that this refuelling method will work well on the mooring..
Then cut the hose pipe about 2 m from the end and put in a joiner. Mixed up the antifreeze 5 ltrs in about the same amount of water.
Started the engine and ran it on the muffs and water tap for about 10 mins until the water coming out the return was warm. That told me the thermostat must have opened. Temp gauge was reading about 190 f (80 C) Stat opens at 72 c so I am certain it was going round the engine. Shouted to my mum who is 78 and was in the rain and gale to turn off the tap. Undid the coupler on the pipe and stuffed the end into the bucket of mixed antifreeze. To my amazement it sucked it all up and just as it was empty green warm water came out of the return. This is about right as the system says it holds 9 ltrs and I had about 10 ltrs in the bucket.
Shouted to my wife who was at the helm and standing freezing cold in the rain with numb hands to switch off the engine She had two hoods on so could not hear a dam thing. Shouted louder and off went the engine, she was complaining a bit as she reckoned she was soaked and frozen through. I told her about Anna and not to bee such a wuss. I skipped the fogging phase as I had too much going on. Several others have told me that fogging is not necessary and they have never done it. I am sure others will disagree but that is life.
I then put the leg down to let what water was in it drain out which it did.
like others have said I did not drain down the engine as the antifreeze was well mixed and should protect ok.,
I also purchased a small 60 w airing cupboard heater that I will put in the engine bay if the winter does turn out to be particularly cold. £16.99 from toolstation.
I then let her who was winging and cold go indoors and told my Mum who I had forgotten about that she was excused tap duty.
Put all the covers on had some warm soup and all females suitably warm I set off for home. I got 1 mile from my mums (where the boat is stored) and remembered that I had not pumped out the shower water tank. Told my now warm wife this and the look on her face said it all. So ignoring that look I turned round, Got my wife to wriggle under the tarp, Put the battery back on and we pumped out the water tank via the whale pump.
And yes she remembered to turn off the battery and fuel.
Now sitting by a log fire with a mulled wine.................................. The joys of boating
