Re: 1998 Mercury 125 Power Trim not working
If you search in this forum you can easily find others with the same problem.
First you can jump the solenoids at the trim pump to see if its the solenoid or switch. If you can't get anything going there then you might have a problem with your pump, sometimes they can get stuck like a starter so a couple easy knocks could solve this.
Search the read through posts and see if your problem sounds the same. Creating your own knowledge base in your head because if this happens at the boat ramp and you don't have the internet handy you can solve it on your own.
