Ok A week ago or so I stated there was no spark, then there was spark and every thing ran fine. Well there is no spark again, I tested the PulsePack with the light before it glowed now it does not. I ran the motor 2 times it ran fine. I havent done anything to it aside from change the lower unit oil. Does this motor have a sensor in the lower unit which willnot allow it to run if persay the oil is low? just realy starting to not want this boat anymore due to the one day it works the next it does not. any help would be awesome thank you.
