Ok so my 1998 merc.115 ELPTO 2 stroke has an issue with tilt trim. Switch on engine is sporatic switch on binacle sporatic. How do i diagnose what the problem is? Are there solenoids or relays that need to be replaced if so where are they? The hydraulics seem to be fine if the motor would go. I'm sure others have had the same issue with the there's. Any help would be appreciated.
