I dont post here much, more of a lurker since I am not really an offshore boater. I had to chime in here since I am currently having a boat built with an LSA in it. The motors are redily available, as I have driven several LSA equipped boats already and my motor is on the way to my boat builder. These things are impressive to say the least, less than 500 lbs and way more power than the 8.1HO. I have been impressed so far with my test drives. They do burn A ton of fuel though, 40+ GPH at 4500 RPM (WOT) in a jet application. I bought mine for WAY less than the Raylar motor, fully marinized. I would of considered the Raylar motor, as I like the idea of more displacement, but I just couldnt afford it.
