What about a 502 Mag? They are rated for 415HP at the prop correct? Why can we quote this engine for values or insurance at prop HP and the 500HP has to be quoted at the crank?
I've just always thought of it as a 480HP or so engine.

For values it's confusing since all the black motors are prop hp and the blue motors are crank hp.
And there is a BIG difference between 426-470hp and 471-500hp!

Use the 471-500hp number.
Book value is only an estimate anyway and is for banks to use. They should also include hours as a factor to determine the value of a boat. The same boat with 500 hours on a set of 500's is worth a lot less than one with 200hrs.

So, another question. With a 502 Mag MPI(415 pshp) do you use 400-425hp or 426-470hp since technically the motor has 445 crank hp?
