Finding parts and having them arrive in the country in a proper time is excellent, but somehow information given drops out and other information from computer generated past history fills the space; Please be carefull of this, the phone number I signed up with was changed back to a very old number, caused problems

Crowleys was great, acknowledged and sent my order promptly. However, the shipping wasn't that great, through Fedex, my parcel got slit open and a bag with grommets were wide open but managed to stay until they taped it closed but a package of 2 o-rings had escaped before they saw the cut. have to find them elsewhere I guess. Never thought to ask but I wish you had sent my small package through the mail.

Problem fixed: foot oil was half water on used motor

Bought a used 25 Evinrude then saw the foot oil was half water. Ordered a foot seal kit from Crowley (#396352) to repair the foot, the main problem had been that there was no grommet on the top end of the water tube so I ordered 2 of them also, as well as the o-rings for the spacer tube which unfortunately went missing from the damaged package. Not worth delving into though.

They had the supplies I needed at a reasonable cost with fast shipment and delivery. Very impressed.

Parts were as described and the shipping was quick even with selecting free shipping. Definitely recommend for future purchases.

Problem fixed: Fuel related miss

A relative borrowed the motor, not sure what he used to put fuel in the tank but when it came back the motor had a noticeable miss. There was silt in the fuel tank, it had choked up the fuel cock and was throughout the fuel system. Replaced the fuel cock and filter, cleaned out the tank and fuel lines, removed and cleaned out the carburetor and it's back to how it should be.

This review actually covers several orders. I bought a used boat (2006) and needed to know what I had before taking it out. Used the tech tips and exploded views to figure out what parts I needed to service the Evinrude E-tec 90 hp. The phone support was excellent to make sure we I got the right parts. Changed water pump, thermostat fuel filter and fluids. All the parts and advice came from Crowley’s.

Problem fixed: Stern drive leaked oil from water inlet

After changing oil at spring I noticed that there was leaking oil from water inlet tube and that oil level in upper part housing had dropped. So after reading repair manual and looking trough explosion pictures of upper housing I concluded that there must be problem somewhere in the sealings. Only problem was that its next to impossible to find parts for OMC in Finland. After little searching i found Crowley Marine. Using of web store was really easy and parts arrived to Finland in less than a week. Mean while i had opened the upper housing and located the leak in to o-ring between gearhousing and main housing. When parts arrived work was relatively easy. While I had the whole upper housing opened. I also changed water pump and all the other sealings as well. Whole time it took was about 5 hour. Plus Removing and installing the sterndrive from the boat took about 2 ours each.

Problem fixed: Rusted exhaust msnifolds.

I have a 1988 OMC Cobra 4.3 V6. These engines originally used a one piece manifold/riser unit. I liked these because there was no riser gasket to leak and they were simple to install. I am in a salt water area and we have to change exhaust manifolds every 5/7 years or else you can get water in a cyl and when in salt water this is really bad. The problem was the original OMC one piece units are NLA. I did find out that GLM was selling a conversion kit using a Volvo style center riser set up with a 4" to 3.5" 90* adsptor. I could have used the GLM kit but I have heard of fitment issues with their exhaust manifolds. So what I wound up doing was replicating that kit but using Barr manifolds and risers and OE Volvo parts for the 90* exhaust adapter and hoses. It all fit perfect. A little pricey but in salt water it does not pay to scrimp on the exhaust system.

Problem fixed: The Crankcase was Leaking Fuel

I bought a vintage OMC motor. After cleaning it up, I got it running, but the motor wasn't running well and fuel was leaking from the carburetor. I ordered a carburetor overhaul kit from Crowley Marine and installation was easier than I thought. If you have any mechanical skills at all, you can service your outboard engine. They are there to help and have those hard to find parts. With friendly service and fast shipping, I will return. Thanks

Problem fixed: Normal maintenance of the inboard/outboard system

After about 10 years it was time to replace the driveshaft/u joint bellows and the exhaust bellows. This is not a hard job but you need to disconnect the shift cable on the engine bracket so that you can pull back the pivot housing to get good access to the gimble housing where the bellows are installed. The Cobra bellows install is the same as a Volvo SX, easier than a Mercruiser.

Problem fixed: Motor would stall and flood, water in lower unit with bad seal

The cap on my oil injection tank was plugged, The motor would flood with oil when it got hot from pressure build up in the tank during the week when stored. The Motor would starve when running the motor because it couldn't breath. I changed the lower unit oil on the motors put new seals on the screws and replaced one screw. All these repairs saved me close to 400$ this year, but I bought 2 new gas caps for my old tanks and the rubber seals on the caps were made with a pour grade of rubber they warped so I put the old ones back on the tanks. All in all I was happy
