I saw this up for sale all summer long! Can't remember what it was about it but there was something wrong.
The owner can't have much idea about boats, BHP is for cars, ie. 'braked horse power' it's a term derrived from the way hp is measured on a dyno to do with finding out how much hp loss there is in the drive train (as far as i know!)
'Has a 450 bhp engine as shown in the pictures.'
Looks more like twin 225's to me!
Other than that don't know much about it! i wouldn't trust it personally, seems too cheap too!
