When i rebuilt my boat I bypassed the interrupt switches on the advice of a high performance marine mechanic whom I trust. His opinion was that they were nothing but trouble and since my engines were new and had a low idle that I didn't need them anyway.<br /><br />I'd like to hear everybody's thoughts on the subject. I ran last year without them and really didn't have much of a problem shifting but now I am thinking I'll hook them up and maybe shift even better.
