Hi,<br /><br />At full throttle position the Mercury remote control box seems a bit tight at WOT, and tends to creep back a couple of hundred RPM once underway. I took apart the control box, everything seems fine. While awaiting my ordered service manual, is it likely the throttle cable is just a tad too tight, and if so, is it best to adjust at the control end or the outboard end.<br /><br />Next question, there is a capped electrical connector on the front of the control box, is this for wiring in accessories?<br /><br />Thanks!<br /><br />1985 Mercury 500, 4 cylinder two stroke outboard<br />Mercury control box.
