2001 90hp merc 2001 4 stroke 90 hours. Idles, slow, fast all good and smooth. Hesitation and rough when accelerating out of a no wake zone. B4 I bought this summer, previous owner had carbs rebuilt. Test ran fine. Not run for about 2 to 3 weeks while transporting and mounting. I have water / filter between gas and engine. Thinking carb port may be clogged. Any ideas? Matt -
