I have had this boat/engine model# E40TLCCS for a few weeks now and here these are the symptoms of the engine.
Starting/Idling - Excellent
Idling - 75% throttle - Excellent
75% - 100% throttle - hit or miss. Sometimes the engine will come alive and pick up about 1500 rpm's and run like a scalded dog. When the engine is cold, I can leave the no wake zone and go to 100% throttle and it will run wide open for about 15 mins then when I back the throttle down it will start to ? (sounds like detonation but isn't) I have checked the plugs numerous times and they look good.
I have replaced the spark plugs and used a spark tester to make sure they are firing, compression is fine, replaced fuel lines from the tank to the VRO, new fuel filter, new primer bulb. Everyone I have spoken to, sounds like its the high speed jets, but if that were the case, wouldn't it act this way all the time? The pee stream coming from the motor is strong and consistent, so I know its not over heating. Could it be the coils, going out and not producing enough spark at WOT to burn the fuel.
I am at a loss on this thing. I don't have the money to take it to a mechanic at 150 an hour for something simple that I could have done. Any help would be greatly appreciated.
Thank you!!
