Keel cooling

[Ottersailer]

I have keel cooling and wish to change my coolant. Can anyone tell me a decent brand to use. I need one with good anticorosive properties rater than a staight forward antifreeze.

Go to a jaguar garage and buy the BP coolant, which is used in all alloy jaguar engines, it is very, very corrosion resistant and is brilliat stuff. Use it also to top up. Do not top up with water!!
