Missouri uses the same engine as Iowa, with 40 knots max on the BB engine with 233300 bhp.  The speed cap is easy to hit with regular bve crew.  Stop ruining the ship with other random engines. 
If you think that elite engineers will bump it up to 42 knots, I dont think you should be using elite engineers at all.

To answer some of the previous questions:

@ Tea_Time

The Missouri does not have as much displacement for bulge/belt as the Iowa if you wish to stay at 40 knot overheat.  This means that you will need to strip away much more weight to try to run it at 42 knot (maybe even the rear gun).  So far, I have not experimented much, but was not able to make it go 42 knots even with TWO open T sailor slots.

@dnaa

The Missouri uses the exact same guns as the Iowa, so the range is the same.  They did not make any new gun sets for the EBBs. 

I guess i should correct myself about the iowa speed cap.  It is possible to get to 42 knots if you tweak the weights well

42 with the right weights. Either leave your reps at home or if you had soft engineers.

I am alittle dissapointed with chosing Ebb missouri, i wish i had chosen maryland

Seariously Maryland, thats an Colorodo class and the Missouri is an Iowa class FYI is the most powerful, fastest and strougest class of battleship ever completed by the United States

plus nothing happend very significant on the Maryland compared to Missouri and the rest of the Iowa class, becouse WW2 ended on Missouri and Missouri was the flagship of the U.S Pacific fleet.
