[QUOTE="Johny25, post: 283704, member: 7791"] Reference to the 88' 15hp...... have you set the slow speed idle screw while the motor is in the water in gear as the manual specifies? Also you may have the idle set to low on your tiller handle. You can raise the idle of your engine right behind the kill switch button by loosening the knob, adjusting it by turning it then tightening after you have raised the idle. Idle should be around 700rpm give or take 50rpm if memory serves me. The 74' johnson also has the slow speed idle screw on the top of the carb that may need proper adjusting in the water in gear at low idle.. And the idle adjustment is #39,33,38 in the pic below I believe https://www.boats.net/parts/search/BRP/JOHNSON/1974/15E74S/MOTOR%20COVER/parts.html As for the Merc...... they make excellent anchors :lol: [/QUOTE]
