Sounds like your battery is dead... check the voltage. If not then possibly the starter is bad.

Thanks all, I knew the battery was flat, but I was quite surprised at just how much juice it needed. Tried again this evening with a friends big Merc and it seemed as though we just run the battery down even further. So we decided to hook up the batteries direct. only then after running the Merc for at least five minuets did my BM turn a few times and eventually fire and run like nothing had ever happened.
I’m going to monitor it for a few days. Wondering if the positive terminal under the bonnet could be faulty. Would explain the failed earlier attempt!
