82...thanks for your reply. I'm in Pittsford ( ROC ) The box is the Quicksilver unit that came with the 40 Hp Mariner in ' 86. It uses no gas and runs incredibly well. I do not know if there is a number on the unit as I have not looked, really, but will. I have the ignition switch on the dash with a single lever on the box. The lever has the button on the base to use the lever to advance the idle. Otherwise it is a forward , neutral, and reverse lever with a compression lever built into the lever top for shifting.
I could not find a a schematic to see the guts prior to tearing it apart, kinda like a doc might approach things. Thanks again. Dave
