It's not the motor you're after, but I've got a 2004 191 Cayman I'll be selling soon. Has a 2003 OptiMax with a bunch of newer parts on it. I'll send the for sale ad link your way when I post it. You can decide if it's what you want or not. Boat has a lot of upgrades over the years. Trailer just had all the axles and whatnot replaced. Haven't dunked it since.
