1. I have a used 2000 F80 yamaha motor the digital tach works fine but it will not light up for night viewing when i turn the light switch on. Is their a bulb that can be replaced it looks to be a sealed unit), and what is the wireing code?<br /><br />2. My tilt / trim locks on me when i tilt the motor comletely up. i have to release the set screw pressure to get it to lower a bit to make it operational - Does it lock because it is lower on fluid?
