I have a MCM 200 (305cu'' 8cyl) mercruiser with an alpha I drive. I need to replace the trim position sensor (port side) and I noticed the wiring goes through the transcom in a tight area. I have the manuals for my motor and drive on cd (mercruiser editions) but can't seem to figure out if I need to remove the drive to replace the sensors. I can get at the sensors themselves no problem but fishing the wiring looks difficult? Anyones help/experiences are appreciated.
