90HP ran aground - now runs rough

[rjtesimd]

I have a 2003 90 HP with 350 hours on it. It has been professionally maintained. I was ghosting up to an anchor spot and ran aground in sand/mud. The engine stopped. I just dropped the anchor and walked to shore. In the morning, the engine started right up but it ran very rough above 1500 rpm. Water coming out of system. No damage to prop. It did not overheat. I can ride all day at 1500 rpm, but as soon as I get any higher it runs very, very rough and stalls. It sounds like a timing issue. Any thoughts? RJT

test the alarm system to make sure it is working

Alarm system?

Sorry, you have stumped me with that one. Can you be a bit more specific? Thanks. RJT

Since you failed to post a model # we do not have any idea what 90 motor you have
