Barrus Shire 40, waterless coolant

[Kendorr]

I'm currently having a new shell built and will be installing a Barrus Shire 40 engine. I've seen information on various motoring programs about waterless coolant. Evans do a marine coolant, info here

I can see the advantage of being able to use something with such a long life in a new engine, but would like some advice from those with more experience than me.

Thanks

I can’t see that it would have any advantage on an inland waterways boat with a tiny engine with the power measured in a few tens of hp. Unless anyone knows better of course.

I guess it could be useful on a boat with a history of 'boiling up' (maybe after sustained River usage) but for a properly designed new-boat cooling system it shouldn't be necessary.

Well you don't have to change it every couple of years, and should have good corrosion inhibiting properties.

Do you have to ensure that every last bit of water is removed first?

That was my thought, says it's good for 20 years.

I think you do, but with it being a new engine, won't that be the case?

I guess so, yep.

I would not be so sure, I thought Barrus dyno-tested their engines and that requires coolant.
