Ok folks I am wanting to push her a little harder. 90hp 1994 Evinrude. Stock timing is 28. Ok wth GOOD fuel and oil and all other things being where they are supposed to be how much more can I bump the timing and stay relatively safe. I was thinking maybe about 4 at the most. My thoughts are run it at 24 for a little bit and then check plug color. Aint no books out there like there is for hotrodding fords or chevys. Whatta think fellas?????
