  • Pump leaks
Size: Fits Johnson Evinrude 6-235HP
It's a pretty easy swap, 2 screws, take out old, put in new. Well, the pump is bad. It leaks gas from the unit. Poor quality control.

  • Good Price
Size: Fits Mercury 4 Stroke 25-60HP
The item stated it would fit my motor. Unfortunately, one port wasn't in the same alignment as the original. Very good price and quality looked as good as the OEM pump. Wouldn't hesitate trying their products again.

  • Not worth the headache this pump caused
Size: Fits Mercury 30-300HP
Bought this pump for my Mercury 60hp 2 stroke. After installing installation it ran good and I tried taking it out on the water but had no power when trying to go. Idle was ok that’s all. Got towed back in and took it to a local marina. After paying for the tow and the marina fees it was found to have a bad fuel pump. After they installed an Oem one it now runs perfect with no issues. Don’t buy this. It is no good. ... show more
