My carburator and parts arrived quickly. I installed the carb, made a few adjustments and was on the water. Very pleased with service!!
by

Problem fixed: Motor would not run continuity

Cleaned carb and still had problems running. Looked for parts to rebuild but they weren't available any longer. So I ordered an upgraded replacement carburator. Installed and made a few adjustments and was on the water again

Problem fixed: Stop wiring harness was chewed by a mouse.

Old damaged wiring was removed from the handle shifter and new installed. Closer inspection of the harness showed that this was shorting out even before the mouse did the damage. The motor would cut out for no apparent reason and would not start. Noticed that the wiring harness was chaffed where it entered the hinged handle. We will now have more confidence with this motor.

Great shopping experience! Had order to me quickly with no issues!

Some surprise shipping costs, due to Fed Ex delivering over the border. Would love to have known about them in advance. Other than that, Crowley was good.

Great, only complain would be that my order was shipped partially for some reason, so the missing parts had to to be send in a second shipment, so had to pay taxes twice because of an error from Crowley. Costing me an extra 110$

Problem fixed: sierra impeller failure

installed new impeller kit and housing. After 5 min running, water stopped pumping. Impeller had failed and its key escaped the notch and grooved 3drive shaft. Purchased new shaft and repeated. Same thing happened again. I measured the impeller housing and determinec it was about .030" less than older housings, causing the impeller to be gripped so tightly that its hub failed(fractured).

Found the parts I needed at a reasonable price. Shipping was a little slow but given the current situation - very acceptable. Thanks

Problem fixed: Engine would not run above idle

Carbon buildup in the exhaust tube completely blocked exhaust. Needed to be cleaned so lower unit came off and that was completed. Replaced the water pump impeller as part of the job. Engine is back to running normally.

Great !!!

I was told upfront that shipping would take longer because of Covid and if I needed the parts ASAP they couldn't supply them that fast. When the shipment came it was 1 part short, CS took care of that without a hassle and is sending the missing part to me. Being upfront about the shipping delay, and immediately taking care of a missing part of the order, tells me this is a very reputable company to do business with, I would buy from them in the future without hesitation
by

Very good! Order was shipped promptly. Returns were handled with no problems. Would definitely recommend shopping here.

Problem fixed: Low water stream

Towards the end of last season I noticed the motor wasnt pissing water as strong as it should. Also noticed that it took longer before a stream formed and the water was hotter than normal. Decided to changed water pump impeller. Removed the lower unit and found a piece of water pump lodged in the discharge tube. Replaced water pump, and a few other plastic and rubber pieces. No problem.

Their site for part identification is AWESOME! As long as you have your numbers. This order took the USPS quite a bit longer to deliver during the Christmas season. Arrived the night before I went out hunting again.
by

Problem fixed: Previous owner said he never replaced the water pump. So, i bought a new one.

Really, this lower unit is easy to remove. Easy for one person to do. Installing the new pump went very smooth. Unit squirts very good.

Problem fixed: Hard start and poor to no idle

Got this engine home and expected dirty carbs. Closer inspection also revealed the idle mixture screws on both carbs were snapped off by previous heavy handed mechanic. Upon disassemble i found a missing gasket as well as a small amount of dirt in the carbs. Cleaned and blew everything out, replaced 4 tired and or missing gaskets, the new idle screws and tension springs and serviced the lower unit and is good as new. All for $60 worth the parts and less than 2 hours if my time.

I have used Crowley marine online parts for at least 7? Years. Prices are if not the best, close enough. On time I was I dire need and they shipped over night that day. It's the personal touch. This order was simplistic, and the online images make repairs a sinch..

Problem fixed: No water on telltail and fuel leaking from primer bladder

Long story short. Carb rebuild for diaphragm of primer, then new Impeller, new water feed- copper tube, and lastly the failed grommet on the tube engine side. All shipped in 3 days including cross shipping and arrived two more days later. I never review, but for them I will. Congrats Crowley Marine, you stand above and beyond in my book. And I am in sales, so that says something
