Glitch with jet engines in water

[Oxytropis]

Decided to take my science rover into the drink and much to my surprise I got some very strange graphical issues.

The way the launch effects moved across the surface of the water made for a nausea inducing experience. Even at full throttle I couldn't get over 5 or so meters per second not sure if the unretractable gear sticking out was responsible for that or water viscosity is now the same as tar.
