Default Suzuki DF115 Alarms Over 3000 RPMs

Motor is a 2017 Suzuki 115 horse power 4 stroke engine. We ride the boat all day at 2500 RPMs with no problem. IF I push it to over 3000 RPMs it immediately ALARMs!! I reduce the RPMs to under 3000 and all is good, I think?

Water pilot is squirting water, but the pilot water pressure does not increase with the RPMs. I do not know if this is normal or not. Anyone experience this or know the cause of the alarm??

It is under warranty right? Bring it in.

Thanks, but there are no authorized dealers close by. I figured that I would end up dragging it somewhere at some point.

Can you tell what the code is? The check engine light will blink a sequence of lights to tell you, like 3 flashes then 2 flashes for a 3-2 code.
It sound like possibly a bad neutral switch not telling the ecm it is in gear and limiting you to the 3000 rpm. or its overheating or low oil pressure and limiting down to that for protection mode.
