I am having HELL with a 2004 115 merc 4 stroke ,,, it has been getting worse ,, hard to start like the starter is dragging ,, changed battery ,, did not help ,,, check cables ,,, nope ,,, well I thought starter was bad ,,,, NOPE ..

it sometimes pops when it does not start ,,, but when it starts it runs great ...

it sounds like a timing issue ,, it is a EFI 4 stroke ...

how do you set/check timing on this motor ??

call me 580-212-0285

or what the heck is the problem???????
