I have a 2002 150hp 2-stroke Suzuki outboard motor. My power trim and tilt stopped working yesterday after flushing motor with the thermostats out. It was working fine before and now it isn't working. Right after flushing, neither the remote control switch nor switch on the motor worked. I replaced the battery and let the motor dry out as some wires may have gotten wet during the flushing. I also loosened (but did not remove) and retightened all wires to break up any corrosion. Now, the PTT works but it only goes up - not down. The motor goes up by pressing "up" and also up by pressing "down". It's the same at both switches. Anyone have any ideas what this could be?
