I had now issue with the store. I accidentally ordered the same part twice, and when i realized this, I contacted Crowley and they immediately removed the duplicate and credited my account.

Problem fixed: Over heating

Replaced thermostat. removed thermostat housing, old thermostat and washer. blew air thru to clean it out, installed new washer and thermostat. Done. Works like new.


Ordered a prop for a Merc. 60hp trouble free Good service part arrived early all good...

I got the part I needed. It was exactly like the original and when installed worked perfect. Thanks for the good service.
