Getting ready to pull the trigger, and am current looking at a couple 2007 SAN 210's. I found one with an Excalibur and another with a ZR6 motor, both at similar price points... <BR>I know the pcm Excalibur has 330 hsp, and the ZR6 has 375. Is there any other differences between these two motors?? Does the ZR6 have Aluminum heads to produce the extra hsp? <BR>All input/help appreciated. <BR>Thanks!

Justin, if everything is equal[boats} go with the ZR6, closed looped system ,don't have to worry about freezing VA. and NC. I have had three boats with the ZR2; 2005 210, 2008 210, 2009 220.Also the extra hp can't hurt and runs at a lower rpm at wake board speed then the Excalibur.
