The throttle only doesn't work on my 1989 glasstream with a 150 mariner. It's a quicksilver unit, will attach pics. From what I understand there is no direct replacement. Is there a box and cables that'll fit? I tried taking the box I have apart and cleaning and lubibg it but it only made it worse.
Yes a mercury control box from like 1989 thru like 2005 will work fine. You might have to do a little extra wiring for the power trim like add some jumper wires. Your control box is older than 1989. Like 1986-1987.
