Great! Return customer. The online parts catalog makes finding parts so easy and I know they’ll fit. OEM brands is a must, and they have it or can get it fast. Prices are best around on almost everything and 1 call to customer service answered ALL my questions. Preferred vender.

Problem fixed: Full service tune-up (used boat)

I checked all the boxes on this used boat with unknown service history. I replaced everything from spark plugs, thermostats, fuel pump, both fuel filters, fuel line, and some miscellaneous missing/broken items from the cowling. Crowley had it all!

Have shopped around at many places while ordering parts to repair a 32 yr old boat, Crowley Marine has definitely stood out. Besides the normal no issues ordering, fast delivery stuff, Crowley has an easy to use site that provides part diagrams/lists and a serial number search tool. If they do not have a part Crowley went as far as to provide a nationwide tool to help find it. I know Crowley wants me back on the water as much as I want to be there !

I ordered 2 thermostats. Only 1 came in, so I called Crowley, got to talk to a real person, and they realized the error and expedited the 2nd one immediately. Yes, the original order had an issue, but by them making it right, thats worth 5 stars.

Problem fixed: overheating on one side of cylinder block

one bank of 3 cylinders was overheating. Didn’t realize their were two thermostats ,one for each bank of cylinders. Removed the overheating side and it was in very bad shape and rusted closed. Replaced both thermostats since they were probably original with the motor (36 yrs old!). Haven’t been on the water yet as I am also rebuilding the water pump. I’m certain this will fix the problem.

The fact that I live in Australia and buy from you guys in the US says it all. Only the delivery time (about 20 days) seems a bit excessive, but probably there is not much you can do about it.
