Originally ordered water pump repair kit (expedited), The first kit received had been opened and received with no impeller. Replacement kit (complete) was rushed and received (Fed Ex) in two days. Crowley responded with urgency as expected.

While inspecting my 2000 25hp outboard after a recent fishing trip I noticed the the shift actuator cam was broken. Surprisingly the motor still shifted fine. But I preferred to have an intact actuator. I found one at the CrowleyMarine website and ordered it. 5 days later a part arrived....the wrong part. An email to them, with a photo of the wrong part, explained it all. They sent me the correct part within 3 days of my email. I was pleased with their fast and hassle free correction of my order. No additional cost to me.
