I was fishing this past weekend and I couldn't get my motor to trim down. The trim motor sounded like it was going in slow motion, I was able to bounce it a couple of times and it went down but then it wouldn't trim up. If I have to replace the trim motor my questions are is it something I can do and is there something special I need to do. It looks like the trim and tilt units are together as 3 parts. Can I test something before pulling it out. I recently lost my job and I don't want to take it to a shop and spend big $$$. Thanks in advance
