SRT8 smoker craft Posted August 22, 2012 Author Report Share Posted August 22, 2012 I had that same problem... With my last motor... High speed jet was plugged in my carb.... Seafoam cleaned it out... Heavy heavy dose of seafoam... I am going to try that and replace the plugs hope that's the end of it Link to comment Share on other sites More sharing options...

SRT8 smoker craft Posted August 26, 2012 Author Report Share Posted August 26, 2012 Thanks for the info guys I went and bought a sparkplug tester and my top plug is bad (Thanks Tybo) hope that will be the end of my issues the coils are all firing so it must be that plug (found out the coils work the hard way DON"T touch a inline spark tester while the engine is running LOL) Link to comment Share on other sites More sharing options...
ttahhan Posted August 26, 2012 Report Share Posted August 26, 2012 I fished a tourney on st clair sunday and on the way out we were running 40mph and the motor bogged and we went down to 25mph but it sounded normal just no power , when we slow down you can feel the 3rd cylynder kick back on and start powering the boat it works fine at idle but as soon a you throttle it it boggs down I think it's a coil/plug or a carb/fuel prob . I am just looking for advice before I take it in hope this is the end of my engine issues it's only a year and a half old Hello start by replacing the spark plugs one of them might have a hair line crack, Fuel problem being a year in a half old highly unlikley however the fuel filter could be clogged and the worst case scenerio which again i doubt cause of age of motor, the lower end clutch packs could be burned out, caused by water entering through a worn out seal at the [propeller shaft....to check this open up drain plug and ensure the oil is not milky white....hope that helps Link to comment Share on other sites More sharing options...

Meh it was like getting nailed by a BBQ lighter but really fast LOL but it did elimanate the posibility of coil probs I checked the one that didn't light up the tester on purpose to make sure the coil was firing Link to comment Share on other sites More sharing options...
