Good Afternoon All!

My brother has an issue! He has a 1992 Bass Cat Pantara with a 200XP Rude. The power trim and tilt now has developed an issue. It will go down but will not go up. It will do the same thing at all 4 points on the boat. I told him to look at the fuse block but his is not set up like my Ranger. He said you can hear the pump/cylinders work going down but will not go up at all.

What do you think the problem is?

Thanks for your help!
