I have a 2006 Yamaha 150 2-stroke that is bogging down in steps. It will take off at 4000 rpm's but before it planes out it will drop to 3000 rpm's then about 3 seconds later drop to 2500 rpm's and 3 seconds later down to 2000 rpm's. I am holding the throttle steady the entire time. Once it hits 2000 rpm's I can hold the throttle steady and it will jump back and forth between 1500 and 2000 rpm's. The boat was running fine all day and started doing this after i ran over another boats wake (Nothing that i haven't done before). The water pump is running fine and the engine is not over heating. I checked the fuel filter on the engine and found nothing that would be stopping flow to the carbs. I put brand new spark plugs in it about 3 months ago so i don't think that is my problem. Help??
