what trouble, once they are broken in and adjusted once nothing should change if it does, you will know you have a problem before the big bang happens

yeah forget about it...top end every 50/60 hours, total rebuild every 100/110 hours...forget everything but your check book! also you will want to get another boat so you'll have something to run when your motors are being freshened up mid season

Can someone confirm or deny but I understand the 572' has a less than optimum rod-to-stroke ratio.

I believe a 6.535 is std. on a 572 with off the shelf parts and gives it a bad rod/stroke ratio, no?
