Thanks for addressing the fluids devs. I understand the frustration.

Fluid Jets now require significantly more torque than previous such that any fluid jet boat is rendered useless. You can use any boat to indicate this. I would suggest the fantastic example of Kahrstrom's Haukka:

Its a great example because the engines work great in neutral, however, once the clutches are engaged (two buttons to the right of helm, just below window.), the engines die. Boat hasn't been updated since May.

Stay positive.
