So went out today for first time this season. Well heading out I started getting an audible warning twice every 2 min. Then shut it down while my friend hopped in for a pull. Started it up hit the gas buddy got up then boat stalled. After that point anything over like 10MPH and the boat would run ruff then stall. Before going out I installed new impeller, plugs. Distributor, fuel filter and fuel water filter. Any ideas?

That alarm means a sensor is reading something out of parameter. However, you'll need to connect a DTC to find out what's not right. As Wakeman said, fuel pressure is a likely candidate but the IAC on those engines is a failure prone sensor too. Post your engine serial number and I'll check if you've even got a fuel pressure sensor.Fixing everyone elses boat just so I can use mine...
