There is no original place, a lot of normans were sold as bare shells, some with kit fitout, some as finished, all with different or no engine options. You need a tape measure.
Ah I didn't realise that. I assumed they all came out of the factory with a standard set up.
So I need to measure from the control box along the inside of the boat and then across the back to the engine. How much extra should I add to allow the engine to move side to side?
