Welcome to RIBnet Biff.
Sorry, my tame engineers are a little too far away from your part of the world!
I see you've got a JMD - I undertook my RYA2 5 years ago in a 6.1m Temptress, which is the same hull as the JMD
. I subsequently had a trip on JMDs last demo boat, when I was first thinking about RIB ownership, which also had the 175 'rude on the back. Very sure footed, as I remember it.
I'm sure you'll get a recommendation from one of the North Eastern members shortly.
