Cool, thanks for the info. FO said that there is a problem with "the" switch, I will dig into it and see what the story is, but I needed to know what they were supposed to do for me.
My new (except it's a 1987) Sunbird has a Hi-Lex throttle, that has two rocker switches. One is on the lever, marked "UP DN" and the other is on the "wall plate," marked "UP TRIM DN" . . .
It's a MC 185 w/AlphaOne I/O drive.
I just got a Sunbird 195 with MerCruiser 185 with AlphaOne I/O drive.
This is my first I/O boat. The engine needs a little TLC and checkout before I take it to the lake (seller got it to kick over with ether but we didn't want to actually run it). With my outboards, this included either muffs...
