Sorry to pick your brains, but i recently purchased a ocean master.
Story about it is, its Shane stones old boat was neglected at channel point for years, then taken to cullen bay where it sat a little longer. All i know is the motor is a 2007 etec 90, the only motor that was fitted to the hull and only 140hrs on it. So i assume its a 2007 modle 511. Some say that there were a gen 1 in the 511, a gen2 and a gen 3 is this true. Also no mod plate on the hull why?
