Have you checked the fluid level? Is there any indication of a leak around the trim/tilt rams?

It sounds like a valve isn't opening. I don't know too much about Merc trims but if it has a dual ram (one for tilt and one for trim like Yami), it sounds like your tilt ram goes in but the trim ram isn't moving.

Is there a manual release valve you can try? And as Brian said check the fluid level.

I'm sure you're smarter than this but I'll mention it anyway. Maybe someone engaged the engine's manual support lever. That's probably not likely though since your engine's going down half-way.

thanks everyone the problem has become intermittent which makes me think it is a electrical contact problem I will be going through and clean all the associated connectors

I had the same problem on my 96 Sailfish

Quite coincidentally, a relay died on one engine about the same time the hydraulic assembly began leaking on the other. We were anchored in shallow water for a picnic on the beach when it happened and we manually lowered the engines to get back to port. The relay was a simple fix ($15 part). Replacing the whole trim/tilt assembly on the other engine was NOT!
