So my Yamaha 250 sho is having trim issues. When I press trim button up it works perfectly fine but it just clicks when I press down. I have to keep flicking up and down button for my motor to finally start trimming down. Is it a bad relay or loose connection somewhere?

Mine does that too. The relays are the easiest thing to replace and probably the cheapest. I think I’ve replaced one, but mine have always worked if it piddled with them enough and switched them around 

Super easy to replace, at least they were on my Merc 150. I just ordered them off Amazon and it literally took no time. I replaced them both even though it was the down one giving me problems. 

Replace both while you are at it and save yourself some trouble later on.

There’s some good You tube video’s that show you how to check and change your trim relays on your Yamaha.  Pretty straight forward and easy.

I had a similar issue with my Yamaha 90. Turns out the lift motor was going bad. And the odd thing was going up was no problem. It was the trimming down where I had the issues. YMMV

I’ve been told that’s what’s going on with mine. It’s had sporadic issues for 3 years maybe more. Sometimes it trims up non stop when you aren’t touching any switch but you can stop it by hitting down a few times

 

those relays are sensitive, I accidentally took one apart once………

I don't know this for sure, but I was told if the relay clicks when you press the button then it's doing the job. I bought an aftermarket lift motor, watched a video on swapping it out, and had it done in 15 minutes. No issues since. I also realized just how sluggish my OE part had become after getting a fresh motor installed. 

Problems like that are what multimeters are made for.  It lets you diagnose the actual problem instead of guessing.
