Have 85 235 and the up trim seems to be acting up. When I hit the up trim either on the throttle or the motor the up will not always engage if I keep hitting the up it will sometime go. When I looked at the trim box in the motor and it the up button I can hear the solinoid click but no action. Can someone tell me which is the up solinoind and can someone confirm if this is the cause or perhaps something else.
