I have a 2001 150 hp ficth and my problem is with the gauges . when idiling and mid range tach is fine but when get into higher rpms tach goes way over to 7000 and when i hit the trim button the tach drops way down . I have gone over and replaced all grounding to the console and guages . and never worked . Also when idiling my gas gauge does not keep a steady signal it bounces around but has a beat to it .almost like a pulse about every 2 secs , any input would be appreciated .Motor runs great without a miss .
