2004 250hp OX66. When I first start up, it seems to idle too fast.. About 1100 rpm. Clunks pretty hard when going into gear. After it warms up, then it idles right at 750 in gear. If I turn the idle screw down to where it idles good at startup, then after it warms up, it idles at about 500 rpm in gear and chugs a little. Have to stay on the throttle to keep rpms up. High idle is primarily on on first start-up and really bad when the weather is colder. Makes a little hard to get around in the morning when idled up at tournament launch. Any suggestions on where to start looking. Manual does not have a troubleshooting tree for this issue.
