I have a 2004 150 HP Yamaha V-Max. At times when I start to trim it up it won't go up..I can trim it down without any problems just for a second and then trim it up. I thinking it may have a bad trim solenoid.!! I checked for a loose wire and didn't see one on the solenoid.. Is there any thing else that could be wrong..I've never had the first thing go wrong with this motor..KNOCK ON WOOD.....
