Submerged Boat Yesterday, Power Trim Issue

[King_Colby]

OK sorry I'm new here but need some help. Yesterday my plug came out and the boat submerged quick. I made it to a nearby bank and pulled it onto it. However the back in did get submerged to entire motor under water. I went swimming put another plug into it and had someone pull the boat until the water was out. All went well, the motor fired right up. I did drain my gas today and change the plugs. No other mechanical issues with the boat except the power trim won't go up. It goes down just fine. There is no click when pushing in the up position on any of my trim switches. Bad solenoid? Wiring issues due to the water? Trim motor shot? Any ideas please....

What kind of PTT does it have? Pump/reservoir in the boat? Could be a bad trim solenoid. Some PTT systems have a trim limit switch. Maybe it broke or was unplugged in all the excitement. Does trailer (or tilt) switch work?

That motor was submerged in freshwater, right? You know to run her for 45 minutes to dry her out, right?

If saltwater, you should pull her crankcase apart and clean her up.

Im not by the boat but found a pic online of what is in it. Yes it was submerged in fresh water, today I changed the plugs and emptied the tank then put fresh gas and mix in. Let it run for 3 hours in my back yard.


Also I forgot to add the trailer switch only works to trim it down just like all the others.

The trailer switch is for raising the engine not lowering it. Since the trim motor does run in one direction, I would be checking for shorts or opens in the wires, and swapping the up and down solinoids to see if it makes a difference

my guess one of the relays/solenoids is stuck or in need of attention.
