EXCELLENT - - I have purchased from Crowley Marine in the past and their products have always been top notch. They ship immediately and package items with care. They are true Professionals. I would not be able to keep my old items running smoothly without them. Thanks -

Problem fixed: Rebuilt carburetor & recoil starter. Replace fuel pump & filter unit. Replaced throttle cam.
Accomplished all necessary repairs using replacement parts ordered from Crowley Marine. I have been using this wonderful ole trolling motor for over 4 …
8 years now. It has done me no wrong. The last fishing trip it began to act up. I was on a 2 week fishing trip to Montana so a little JB weld got me through the trip. It was time to finally do a little repair work on the old gal. I rebuilt the carburetor and the recoil starter spring and upper unit. The fuel pump was leaking- JB Weld closed it up until I could replace with a new unit. The throttle cam was worn to the point it wasn’t allowing full throttle. A new cam fixed the problem. All parts were ordered from Crowley Marine. Getting old replacement parts is becoming harder and harder to find. Crowley Marine really helps in locating necessary replacement components.

Price is fair, service is fine, but reported stock is not accurate making for slow delivery
