2013, 4HP 4 stroke.
Very good condition - we bought it a month ago from the first owner who never got round to using it. Kept under the stairs from new.
We have only been out 3 times, about 10 hours use in total.
I have done an oil change on it to ensure good oil etc.
Very easy to start.
Only selling as wanted a bigger engine for our setup.
We paid £400 for it as an unknown and turned out to be a good engine (so far).
£400 and I will throw in the expertly built stand :P
