The Squalo boat features an animated steering wheel, throttle, and props using the throttleboat and rudderboat animation sources, these stopped functioning after 0.4.7.0.

Demo video of them working in 0.4.6 RC3:

This is likely the same problem as the animated flags on Neg's trailer - those input events are evaluated just for Driveable=TRUCK, not BOAT or NOT_DRIVEABLE (trailers and loads)
