oem vs aftermarket

[adaptolife]

The fuel pump quit on my 92 130. Ordered an oem pump and installed. The old unit was made by promarine. What is the difference between the two? The Yamaha one was only $42. Online price I saw for a promarine unit was $56.

I have not heard of promarine anything. Guess that I don't get out much.
