"i have an '02 merc 4 stroke 115. it ran fine earlier this season but now it surges and misses at any rpm over 1800 or stalls out when trying to go faster or trying to put in neutral. Sometimes it will start and idle fine sometimes i have to let it sit for awhile before it'll fire up. i drained the tank, changed water/sep filter, changed plugs, and have filled tank with clean fuel and added merc. fuel system cleaner per dealer advise and it still has same problem. I don't know but it seems to me to be dirty/bad injectors but i don't have any idea how to check or fix it. any help would be great! motor has approx. 96hrs. on it. thanks"
