Customer Question

I have a 2009 four winns h310 with a 496 Mercruiser and it won't go past 3500 rpms. Is there a security setting that would be causing this? I normally cruise at 28 mph @3100rpms but today I could only get to 22mph at 3500 rpms.

Hello my name is ***** ***** am I speaking with?
The engine does have an alarm system that would limit rpms in case of a problem. If there was a problem the alarm would also be going off. Does the alarm system work on the boat? Are you getting any alarms?
