Will this work on my 2011 Mercury 90 efi outboard engine? It say the right part number, just would like to make sure.

It worked for my 2012 mercury 115 4 stroke. Just check yours first by taking it out and connecting it to a battery to see if it spins. Mine has two pumps a low and high pressure plus a float switch. Not sure about the 90.

Alot of reviews on these non oem pumps say they will not perform to oem specs is this a common problem or just a few out of say 1000 ?

I have installed several of these pumps with minimal issues. I had one I had to replace but believe the issue was caused by contaminated fuel.

The polarity of the wires is reversed

This pump works great, but the polarity of the wires is reversed. The low price is worth a little mod to the wiring however.
