Scott......it is not my boat. See above for an explanation but it belongs to some rich doctor with money to burn on new motors every few years I guess. We ran at 4000 rpm for the day and the boat will be heading in for service this weekend. This was the first trip out where he tried to take the motors up over 4000. He ran at 3100 for the specified time then yesterday went up to 4000 but never tried more than that. When he tried to go over it would drop to 3400 and then go up and down between 3400 and 4200 rpm.
