All the parts i needed Thanks

Excellent merchants, genuine OEM parts and fast shipping to Perth, Western Australia...faster than stuff I order from the East Coast of Australia. Highly recommend Crowley Marine!

The salesman was very knowledgeable and very helpful.


Overall, the experience was very good. The parts catalog was very easy to use and showed prices and inventory availability. Online ordering was a snap, and the order shipped quickly. I received the wrong order, but the company reshipped the correct materials immediately with no fuss.

Excellent. I appreciate the OEM parts diagrams. Fair prices too.

Problem fixed: No water from telltale.

New water pump and thermostat diaphragms. Sucked up some sand and scored up the pump wear plate pretty bad. Diaphragms we're deteriorated. Cools normally now.


Prompt service. Good inventory. Responsive to questions.
