My experience was ok but I had to wait 4 weeks to get a water pump gasket for a Mercury outboard. That is way too long. I normally get parts much quicker from this supplier.
by

Problem fixed: No water from tell-tail tube.

The gasket under the water pump wear plate that came in an after market repair kit was the incorrect gasket for this motor. I installed the proper gasket and the pump works fine.

Crowley always has the parts I need for my Mercury outboard.

Shipped the wrong part and upon notification they responded immediately and over nighted the right one to me. Great service !
