Ok I need a little bit of smart guy help on this subject. I have a 2008 Pro XS that all of a sudden decided that it doesn't want to have any power coming out of the hole..hole shot is almost gone completely!! To follow this up on the top end I seem to have lost close to 500-600 rpm. Where should I start ? I talked with a good friend who believes it may be a spark plug gone bad.. The last trip out prior to today the motor was running strong, all over 5850-5900 RPM. I did let the boat sit for 2 months with no STAYBILL or any other additive. I did put some fresh gas in this morning and still no difference... I live in central Ga and do not mind driving to have my motor looked at by someone that comes highly recommended!!

Thanks in advance for all comments and post!!
