relay for trim switch

[Big Dannyboy]

The trim on my 100 hp Mercury outboard does not move in the down position. I am told the relay may not be working. Where is this located and what does it look like? This is a one cylinder type trim.

Re: relay for trim switch

On the 150 is located on the back of the motor. It looks like two small boxes. One is for up trim and the other one to lower the trim. You may need to unplug these square small boxes which are the relays and clean them. they might have some rust. You might have to buy a new one. The same thing happened to mine and I cleaned the relay.
