does anyone know what types of gauges will fit the 1996 shabah 180 if I wanted to replace them all? I'm having trouble with many of them not working.

Most of the time that kind of problem is due to poor/failed wiring connections. Moist / damp air and electrics dont mix well and the connections will corrode sooner or later. I would start by checking & cleaning your fuse contacts located up underneath the dash against the hull. Disconnect the positive side of your battery first.

IF, you feel you still need to replace the gauges, you will just need to measure the diameter of the hole they came from. Finding original Mariah gauges is difficult but not impossible and you wont find them 'new'.
