Starboard drive will not trim out
 

I recently purchased a 96 31' Scarab. It has twin 454 efi's, extension boxes and bravo 1's. My issue is that the starboard drive will not trim out with the individual trim switch after I am up on plane. If I use the trailer button to get the drives out just a little I can then adjust them individually as needed while running without issues. This only happens when the drives are tucked all the way in after I am on plane. If I am at idle and use the trim switches both drives work at they should. I am thinking it is a trim limit switch issue. Am I on the right track or is there something i am missing? Thanks

it will either be the trim limit switch or the trim limit wiring is breaking down. Which is what I found on mine after buying a new trim pump
