Update. Took it out yesterday to pull the kids tubing. Now it isnt idling as smooth as it should. Also getting some sputtering at lower rpms. Still starts fine and never dies or even comes close. Distributor cap/rotator/spark plug wires on order. After a little tune up we will see where it stands. It didnt drop out at high rpms though. Moody engine.
Replaced distributor cap/rotor/spark plug wires. I checked 4 of the 6 plugs, they look normal, but i intend to replace soon anyways. However now the engine runs like crap. Sounds terrible. Runs but not right. I didnt cross wire anything and yes i am sure of it. My concern is how the new spark plug wire connect to the plugs themselves. There is no snap when they are pushed on. I dont see how a good electrical connection could be made as loose as they feel. All 6 feel the same too. Only on the plug side though. The cap side snaps as normal. Confused. Is there different connector sizes and the place sent me the wrong plugs......more investigation to come.
Maybe squeeze the connector with some pliers then press them on. I have never had to do that before. Also these are quicksilver wires.
I would not be concerned with the snap of the spark plug wires at this point. It's likely fine. All the spark plugs and wires are designed with the same size connection.
I didn't "Yet". I wanted to run it between each item to know for sure what resolved it. At this point I have to get the engine back to a runable state to troubleshoot the original problem. At this point it is running as if one of the cylinders isn't firing(IMO). It makes a terrible noise once above 2500 RPMs. I am scared to run it up any higher for fear of damaging something major.
I tried to upload a video of the running engine in its current state but I guess the file is too big.
also I took a glance at the coil and noticed there are only 2 wires going to the coil. Positive and negative wires I believe. The distributor to coil cable is removed during this pic. Well crap, apparently the forum file upload isn't working at this time.
Update. Well i know why the tune up made the engine run like crap. The wrong rotor was shipped to me. The pn is supposedly correct but the part is clearly wrong. It is for a v8 instead of my v6. They are supposed to be sending me a new rotor and distributor cap. See pic.
Got the correct rotor shipped to me. Installed it. Also replaced the coil. The boat is running great so far. I couldnt get my initial problem to happen again either, yet. If it doesn't return I will update the post. I believe the coil may have played a big part of this. All in all just did a tune up plus the coil. Spark plugs/Spark plug wires/Distributor cap/rotor/coil. Fingers crossed for future runs. Thanks for everyone's help and suggestions.
I know it's a old post but did you get a alarm beep when the 1sec miss happened? I have the same issue and I'm leaning toward the coil being the issue. My motor will drop rpm for less then a second like the key was turned off and back on instantly. Seems to only happen once the engine is warm. I know I have to track all the ignition connectors but was looking for more info.
Thanks,
Mike
