Which HP version do I have

I am looking at a 2009 seadoo challenger 230.
The seller claims it has the 255hp motors (510HP total)
It does not have the external intercooler(s)
Can this be a 255? or is it the 215
I would like to know for sure what I am buying

Since no one replied I will reply to myself and anyone else who might have this question
The 215 HP 4 Tec has an internal inter cooler
The 255 HP has an external inter cooler. It is an aluminum box strapped toward the stern of the boat.
If you don’t see the ugly aluminum box its not a 255 HP 4 tec
