What Happened
by David from Montrose, Colorado on December 12, 2014
When opening the package I found a oversized cut down unmarked box inside a shipping box with packing around it. Good to this point, BUT when I opened the cut down box that had no labeling or ID I found the pump had been rattling around with no packing or bracing to contain it. It was shipping worn enough that I checked the shaft for true before repainting it! It did not contain ANY other items such as gaskets to mount it as pictured. I am very surprised at sierra for the condition or the packaging and product as shipped.

The pump fit perfectly,(aside from having to switch the bypass hose barb fitting to a 1/2" pipe plug). I have Merc HP 500EFI's .
