One question on alarm system. Will my 2005 Optimax sound alarm when it reaches maximum rpm's of 5750? I installed new repaired and blueprinted prop from Mark Croxton and during run to WOT I reached 5800 rpms (Analog tachometer)and alarm sounded (Continuous Beep). I backed off a bit rpms dropped and alarm stopped sounding. This is the only time I've ever heard alarm since I have owned boat (Except for startup). I'm going return prop to Mark for some adjustment to lower rpms a bit just if I was correct on alarm. Thanks for your information in advance.
