Autumn Ember on Instagram: "0.0–1.0s: Launch preload—throttles snap open, props cavitate briefly while the hulls pitch up. Thrust lines sit high, creating a strong nose‑up moment. 1.0–2.0s: Cavitation clears → sudden thrust step. Drivetrains see a torque spike; transom enters bending + shear as four outboards load simultaneously. 2.0–3.5s: Structure can’t redistribute fast enough. Engine bracket bolts go into combined tension/peel, exceeding joint capacity. Watch the transom flex lag the thrust
