Great !!!
by

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

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.

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
