Mariner 70 trim & tilt wont work

[freibling]

I have a mariner 70 hp and the power trim just makes a clicking sound when trying to lower it. Any suggestions would be greatly appreciated.

The "click" could indicate that

1) the fuse which feeds the trim motor is blown (you are getting power to the relays, but not to the motor itself) - so find the inline fuse under the cowl and check it out.

2) the relays are shot - less likely since you hear the click which tends to indicate they are "switching on", but worth a check - you can bypass them (hotwire) the trim motor and see if it powers (after you have checked the fuse).

3) the trim motor is toast - the click could indicate that the relay is "on" and sending power to the trim motor but it's not working...
