It was a great experience. I got the exact OEM parts I requested and my 1989 Mercury Outboard 25 HP runs as it did the day I bought it new. Thanks for the great service Crowley Marine!

Problem fixed: Primer pump would not prime. Tough to start.

I removed the carb and then the bowl / primer pump from the carb. I then removed the primer pump diaphragm. I installed the new parts from the kit and put it all back together. After pulling the primer / choke out the motor started on the first pull. It has been perfect ever since.

Needed some parts for a 1990 25hp Mercury outboard. All of the parts were in stock and delivered a day early. They were also less expensive than the local Mercury dealer. I would definitely recommend Crowley to my boating friends.

Problem fixed: Priming Assembly Broken

Bought a 1993 Carolina Skiff with a 1990 Mercury outboard. Bought it for the boat, the motor wouldn’t run. I planned on buying another motor, but decided to see if I could get the old Merc going. I fixed some minor issues, tuned it up and changed the lower unit lubricant. Runs great.

I highly recommend Crowley Marine. Their service was fast and accurate, and communication was great to deal with a mistake that l made.
