numerical DE solution mathematica

Hello,

I would like to solve the following D.E. numerically using Mathematica (with NDSolve?) , to then make a plot:

$(0.002419)\frac{dy}{dx}=\frac{( 170cos(377x))^2}{0.0535y-10.61}-4.75*10^{-12}(0.00014y+0.0102)y^4$
and i would like the function to cross 300 on the y-axis when x=0

what would the syntax be?

i thought:

NDSolve[0.02419 y'[x] == (170 Cos[377 x])^2/(0.0535 y[x] - 10.61) - (4.75/10^12) (0.00041 y[x] + 0.0102) y[x]^4, y[0] == 300, x, {y, 0, 3000}]

but it doesn't seem to work.

Thanks.
