Helpful and friendly. I always compare prices and shipping costs among 4 or 5 suppliers and Crowley usually has the lowest combined cost, plus I don't have to wait a couple of weeks to receive my parts. They're willing to work with the customer if you have issues with the order. I don't mind dealing with these folks.

Saved my Merc! Thought my 30 year old Merc finally did it's last putt-putt. Found some of the parts here and there online as Mercury had most every part I needed, listed as discontinued. Came across Crowley marines site and they were able too fill my order 100% and they had better prices on the same parts I found elsewere. Thank You Crowley Marine!

Problem fixed: No control. Control cable came off of pulley. Rebuilt carb.

Local service centers wouldn't touch it. To old. Was going to buy a new outboard, then figured I would tear into it, since mama didn't want a new motor, she wanted a new boat! Found control cable was frayed and came off pulley on tiller handle. Need to remove recoil, carburetor and such to access the complete cable assembly. Replaced and adjusted ca

Problem fixed: Hard to start, sputtering and spitting back out of the carb

Rebuilt carb and also installed new reed valves. Outboard is in storage for the winter, can't wait till spring to get it out and give it a try.

I was skeptical about receiving the correct part for my older outboard, but sure enough everything I ordered was the correct match. Shipping was fast and I had a trouble free repair! I'll definitely be ordering again from Crowley Marine!

Great parts selection. Great prices and fast shipping.

Web page good and easy to use. But almost every item says in stock and ships IMMEDIATELY in high case with green check mark. To me this means now, not two to three days or longer . Over a week getting a part that said in stock, but was not. Price compared to other sites on a lot items a bit higher the others. Not open on week ends to ship , but card charged on week end and item not shipped. Will use site again but will be more aware of faults.
