Re: stuck in full throttle
I remember reading on here somewhere that there are 2 different setups for merc controls, I'm assuming you are using the controls from the 25hp? Apparently it depends on the throttle setup inside the motor (where the cables attach) as to which setup you should be using. If possible, compare the two motors with the hoods off and see which way the cable needs to push/pull to engage the throttle from idle. This very well could be your problem. Hope this helps.
