speed slowing damage and true engine damage behave differently. If you are hit with a speed slowing weapon, you slowly drop down to your new speed. If your engines take damage you drop to your new speed -instantly-.

I'd prefer them both to work like speed-slowing damage does, myself..

Under a SF QNP system, taking engine damage would cause you to coast along at a constant speed and be unable to turn or stop... The speed slowing damage would actually cause you to slow down.
Interesting effects, and it would solve the problem of engine damage being too deadly. Rather than being stuck there, you'd tend to sail by and hopefully have enough manoeuvering power to avoid any planets and asteroid belts in your path
