Customer Question

Hey Tan,,I have a 2007 4 stroke 90 hp mercury. It's been fully serviced, water pump impeller changed, new battery, new online filters and new lift pump float switch. Now I'm getting a 4 beep alarm while on the water and if I get over 4 grand it turns into a continuous alarm and stumbles. I have checked every thing I can think of from the engine to operators consul and can't find it. Can you help me?
