MikeB,
Thanks for your suggestions. I've emailed Talking Headsets to find out if any of those are waterproof and I've emailed the Ebayer to find out if he can help.
Biggles,
Thanks for the advice about the fist mic. I had wondered about getting on, but didn't want to fork out about £70 to see if it worked. I'll let you know how I get on.
Mr Brookes, any ideas?
Tim.
PS would acoustic foam in the cowl of the engine help and if so, how much?
