If the needle doesn't move it's stuck and needs cleaned or replaced. The fuel filter could be plugged...

    Power Trim tilt solenoid troubleshooting 79 Johnson v4 100hp 3 wire PTT motor.

    I looked up the specs on the trim switch it is normally closed type and 8 amp rating. I figured it would be sufficient as it's just a trigger for the coils at the solenoid.

    Ok thanks, I found a used solenoid box assembly with harness on eBay that matches the diagram in the manual. That's my missing link the guy didn't have with the motor that is on my boat.

    CDI troubleshooting intermittent spark Need help please 79 Johnson 100hp V4

    Also meant to ask about the cylinder temp readings in my post earlier, the stbd side was reading 90 degrees while port side was 120. I should just replace the thermostats as it's hard to say how old they are but with the intermittent spark is it possible that's why lower temp due to lack of...
