hot water from outboards

Does anyone know if there is a way to get the hot water from the outboard? What I would like to do is to steel the hot water from the cooling system and use it too warm wet suits, divers gloves and hoods and so on.

Funnily enough I was wondering the same - could save a life if you pull someone out whose suffering from hypothermia.

I think this may be a little rough and ready for you, however one way to get heat from an outboard is to hang a bucket over the stern and collect the tell tale...we did this for years with a bucket the same bucket we kept the ski rope in (this was to stop it getting into a mess). Surprising how much get pumped out the tell tale..Just an idea.

Actually thinking about it why not a hose attachment from the tell to a more convenient point in the boat?

If I'm talking rubbish here, all laugh together.

You could pipe it through your bottle rack or grab rails if you sorted out the plumbing? It'd be like having heated handgrips on yer motorbike... nice and toastie

RIBase
It should be possible to drill/tap another telltale fitting on the cylinder head water jacket (or use the water pressure gauge fitting) but both the telltale and the take-off hose would need to be routed so it runs above the top of the block at some part. This will show that there's enough water pressure to keep the top cylinders cooled.

What exactly were you planning to do with the hot water? Rapid heating is not recommended for hypothermia (my understanding being that - body closes down non essential peripheral circulation when too cold; warming this up opens the blood vessels sending the cold blood rushing back to your heart and killing you). Sorry for hijacking the thread - but it might save someones life.

Who said rapid heating? Warm wet towels or clothing applied to the torso/head/neck/groin only. Leave the arms and legs alone!!!

I've used those thermo-pad thingies on occasion. They work well when they work, but I've had a pretty high failure rate (about a third or so) in some that won't regenerate. They'll liquefy easily enough, but crystallize again upon cooling. They also seem to trigger at random times. Enough so that I've been leaving them in the garage (though I will say the faces on cold divers when you give the thing to them makes it worth the effort...)
