Hi, I have a 2004 Mercury 115 Salt ater Series. Yesterday we used it first the first time this Spring and had a problem at high RPM. It was ideling a little rough, up to about 2000 Rpm then setteled down. At 4500 it would run fine for about 15 to 30 seconds then lose RPM's. Would run rough at 3000, then at 2000 for a few minutes then smooth out after a couple minutes at 2000. Did this for the entire time we ran it, would appreciate any ideas are suggestions as to what may be causing this. Thanks for your Help!!
