2005 Searay SunSport with twin 350 Mag MPI and Smartcraft.

Customer Question

2005 Searay SunSport with twin 350 Mag MPI and Smartcraft. just changed one manifold and riser which required unmounting of starboard smartcraft module. Now have boat running, and smartcraft systems all reset. both engines are suddenly limited to about 3000rpm. boat will do 20 mph, used to do 50 mph. Could I have done something during this simple job that caused this?

Is this related to Guardian mode in smartcraft somehow?

Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
I would start by checking all connections and wires again, esp sensors that may be disconnected. Check fluid levels, check smartcraft module harness connection clean and fully seated/tight. Also check for errors on the gauge such as a loss of communication with engine. May try disconnecting the ground for a few mins and see if that corrects the problem.
Due to it being limited to 3000 rpm's it would appear to be in guardian mode however when in that mode it will usually appear on the smartcraft gauge.
Thank you!
