"ME AGAIN,MY ENGINE IS MAKING

"ME AGAIN,MY ENGINE IS MAKING VIBRATION SOUNDS. THEY ALL SOUND THE SAME IT IS NOT METALIC. IT SOUNDS LIKE IT IS SHORTING OUT OR THE SPARK. IT ALMOST SOUNDS LIKE SPARK NOC. IT ONLY DOES IT UNDER A LOAD. GET LOUDER WHEN I COME OFF PLANE. DESCRIBE IT AS A HESITATION. DHINO CHECKED NO PROBLEM GREAT COMPRESSION ALL ELEC.COMPONETS GOOD. I HAVE BEEN TO OVER 8 MECHANICS AND NO ONE CAN FIGURE IT OUT. IDLES GREAT NEW PLUGS RUNS GREAT. IT ONLY LOOSES MINIMAL HORSE POWER. HAVE USED IT FOR 9 MONTHS HARD AND NO MAJOR DAMAGE AT ALL. IT RUNS GREAT BUT THE NOISE IS HORRIBLE. VERY LOUD SOUNDS LIKE SPARK KNOCK HAS SLIGHT HESSITATION WHILE MAKING NOISE. LIKE I SAID RUNS GREAT. SOMEONE PLEASE HELP ME. IF ANYONE KNOWS A MARINER GURU PLEASE LET ME KNOW. ITS A MYSTERY. ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED. FUEL IS FINE I HAVE CHECK EVERYTHING TIMING FUEL STATOR IGNITION. IGNITON IS WHAT I THINK IT IS SOMEHOW."

"Called another mechanic today

"Called another mechanic today and he keeps telling me what every other mechanic has told me. NOTHING. I really need some suggestions please if anyone knows what my problem might be let me know. It almost sounds like spark knock. just a few short knocks every few secounds while under power. it does it about every 3 secounds for about 2 secounds and get louder when i come off plane. I think its something to do with the electrical system. Does anyone know if Mariner had problems with thier 115 1999 motors. I am here in Brooksville fl. if anyone knows a great Merc man let me know. I would be more than happy to pay for some advice or labor. I dont want anything for free. Just trying to solve a problem. Thanks alot. my email is [email protected]"
