Hi,<br /><br />I ran into some trouble trying to change the throttle cable on my 72 Johnson Hydro Electric Controls <br /><br />See diagram: http://www.ishopmarine.com/ishop/js...011~M0017021~M0017023~C0249582&pCode=C0249594 <br /><br />Part #89 is what I need to turn to remove the throttle cable. Do you need a special tool to loosen this or just a realy small allan key? If it is an allan key what size is it?<br /><br />Thanks,<br /><br />Fuser
