Does anyone know the WOT rpm range on the 1975 Johnson 50 HP (50ESL75B) motor?

Unfortunately I don't have the 1975 book with that information in it.... yes I looked.

Not that it helps, but I do however have the 1976 brochure but that doesn't list the 50hp model... only the 55hp.

The 1976 55hp lists the full throttle operating range as being 5000 to 6000 rpm.... with the engine hitting its 55hp rating at 5500 rpm.

Should I come across the 1975 50hp info you need, I"ll get back to you unless another member jumps in here with it before then.
