I have a 98, Johnson 90 hp boat motor. I took it for service and had to get a new ignition because the key was broke off in the old one. When I got it back, now the trim button will not raise the motor. It will go down but not back up. The buttons on the motor raise and lower good but the one on the control will not. It was working fine until I got it back. Do any of you know a qualified mechanic that works on Johnson boat motors in my area. I am in Wilkes County. Any suggestion would be appreciated
