Hi guys I'm new to this site so don't know if this is in the right place. I am buying a invader 171 with a aq131c and a sp cd trim. The engine turns over all ok but the trim wont go down. I can hear the solenoid clicking. Is there a lever to pull or something to hold it up I need to move or is it just held up by the hydrolics. Is so why won't it come down to play. Many thanks. And any info on the boat and engine or best place to find would be great. I'm in the UK.
