Yea I didn't remember it being that thick when I did my transducer, just wasn't sure if 1.5 would be too long especially for the top mount on the actuator.
Grab the 1" and the 1.5" and see which works better for you. Make sure you countersink, just a bit, the holes with a 3/4" countersink. Once you are a couple threads or more through the fiberglass, nothing longer will make any difference. Holding power is still the same. Plus the top of the acuator's has no pulling pressure, just upward pressure.
