outboard hydraulic tilt - lowering itself

Hi All on my Yamham 100HP fourstroke, I have noticed that the last three times i have gone back to the boat that the tilit has lowered itself from full up down to the resting bracket, anyone got any pointers as what to look for? I guess the system is losing pressure somewhere?

Many thanks Stewart.

manual tilt valve screw?

I had the same on my Honda, the manual tilt screw had opened about an 1/8th of a turn and it used to lower the engine really slowly.. Might be worth a nip up?

Yep could be that or the system is letting air in at a joint or something. Any evidence of an oil leak?
