I have a bayliner 2000 1950 clasic 4 cylinder i/o merc. cruiser engine and outdrive. Problem , up button doesnt work ( part of togle switch on shifter ) down side of togle works so does seperate trailer button work, so drive does go up and down just up button which has limit to how far up it goes. Problem to me seems to be either switch ( at shifter ) or one of those sender starb. side or limit on port side on outdrive ( hockey puck look a likes ) Motor works solenoids seem fine just up button that controls how far up, where should I test at switch in front or one of the hockey pucks ? What does starborn side sender do vs portside limit do ? Is one for trailer ( sender ) one for up button ( limit ) I have in past taken apart those hockey pucks and cleaned them, suggestions PLEASE. I want to do the work myself THANKS AGAIN Also does that togle switch come off seperate from shifter if so how do you get it off ?
