Engine right inside old boat in east (7)
I believe the answer is:
turbine
'engine' is the definition.
(I know that turbine is a type of engine)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for turbine that I've seen before include "Machine driven by wheel turned by flow of water or gas" , "Machine generating power" , "Type of engine with internal bladed rotor" , "Power producer" , "Source of power" .)
