Tune up

[Mercury]

Hi, I am looking for somewhere in Yorkshire or North Derbyshire to put my sr4 in the water to tune the outboard. Non tidal is best, any bit of shallow water will do. I remember years ago there was a place called "Flash Dam" Nr.Chesterfield. but for the life of me I can't remember where it is now. So I was wondering if any one on here knows where it is?

This flash dam?

The Watersports Center at Rother Valley Country near Killamarsh is good - plenty of water.
Book in as an 'engine test' They only permit this from 0830 to around 0930 on weekends -not sure about times in the week
