I have a 2008 200HO that had the power head replaced with a 09 power head 2 years ago. Everything has been fine until today. Went out fishing and when I started home and tried to take off noticed I did not have the power that I should have. It acted like an older rude that I had several years ago. Then it was the power pack, but my understanding is that this motor does not have a power pack.

It acted like a plug was fouling when taking off and would only turn 4800 rpm's. Dealer was closed when I got in. Any ideas what this could?
