1996 225 EFI, rebuilt 5 years ago and less than 75 hours since then. Sluggish when by myself, takes 5-10 seconds to spool up, with a partner this morning it took over a minute of bogging down before kicking in. New plugs last week after it started, no difference. Can't get a mechanic on it before leaving for a T on Thursday, anything a mechanically challenged person like myself can check? Thanks, P_102

High pressure fuel pump or high pressure fuel jets are prob clogged or vaccine line may be broke somewere

Those motors are very sensitive to engine temp if they don't get up to operating temp will cause a bogging problem and also if you idle around with the motor tucked all the way down it will cause a bog while idle set the engine level until ready to take off then tuck it down also could have problems with the fuel recirculation system.......Opti

First thing I would do is check each cylinder for spark. Find no spark, change the coil on that cylinder. These motors are real finicky on the Throttle position sensor setting.
