DF 250 Year to year changes ??

[Qatari]

Hi all
I was wondering if there are any technical change between the Suzuki df250 four stroke 2009 and 2011

I Found a used boat that has 2009 and 2011 DF250 four stroke

and i want to make sure that they are same engines because the look same from outside but i wonder if they are same from inside

Looks like no changes were made between 09 and 11
