I have a fairly new AR190 with ~40 hours of run time. I noticed the last two outings a lost of power/speed and a higher than normal fuel burn rate. It seemed worse the last outing and had a real problem getting on plane with 4 average people in the boat. The engine seems to miss at the higher rpms while trying to plane and can smell what I think is unburned fuel after it has been running for a while. Is this fouled spark plugs or is there other possibilities. Appreciate any suggestions.
