    I cant DRIVE FIFTY FIVVVVVVE! LOL, I hear ya. I tested the will it stop fully with the adaptive at a reasonable I know I can stop speed, it does not stop on my Tundra. It does however make this annoying crazy loud beep and lights the dash up red! I am a fan of the adaptive cruise somewhat. I...

    Scott, Timing is still jumping around. what I meant was that I am seeing good spark at all cylinders. I have not pulled the dizzy and checked for play but I did check when I put the new rotor on, it is pretty tight side to side, I did not check up and down movement. I will try and look for a...

    Update: spark appears to be consistent to all cylinders. It is hard to tell but I am seeing the same hesitation on all cylinders with the light. I am in the process of going through all the wiring again to make sure I do not have a bad ground or connection. After that I am at a loss. I am not...

    I honestly didn't even think of using a timing light to verify consistent spark to all cylinders. I can do that considering I don't have a spark tester currently. when I did the timing setting I noticed it does not hold the timing steady at 10 before TDC in base timing or regular. It fluctuates...

    I do not think it is the bowl overflowing, I have looked at it while on the muffs and I don't see any signs of that. Plus the fact that I I am seeing it with the timing light as well makes me think it is electrical. I do not currently have a spark tester but I will probably grab one and check...

    Yea, I don't think it is a good idea to attempt this with a 350hp motor, sounds like a serious accident waiting to happen. Might work well with small boats but... Thank you for the input though!

    Scott I did have a question about the Tach, if I disconnect the tach, doesn’t that wire feed back to the ICm? Will it still run with the tach completely disconnect?

    Thank you for the input, I will definitely try these things. I do not have access to a spare module. If it does end up being that I may just change out the dizzy system. I don’t want to just buy parts though so I am trying to figure it out.

    Merc 350 bolt v 2 barrel carb fluctuating RPMS

    So I was finally able to get my boat out on a test run. I am not sure what is going on but there is a hesitation or drop in rpm’s. You can feel it, it is not just the tach. I am not really sure what to check, any clues? Could this be a sign of my ICM starting to go bad? I am posting a video so...

    originally it had the two wire sensor but I replaced it when I did the cap and rotor because it was looking real rough! It now has the extra ground.
