I'm looking for the lower plastic cowling for a 1975 4hp Evinrude with the integral tank. I believe the first type was used throughout the 70's but I don't know if the newer type which first appeared around 1979 will fit my model. It also appears that the 4hp integral tank models made prior to around 1979 are not very common at all and do not even appear in OMC literature of the era.
