Hawthorne Marine Power’s product support team has been proudly supporting commercial fishing fleets from San Diego to the South Pacific almost since our inception. With our well-established air or ocean logistics options and an unmatched sense of urgency, utilizing Hawthorne’s decades of experience will get you back onto fishing fast.


Whether you are overhauling a tried-and-true mechanical Cat D353, or performing a troubleshoot using Cat Electronic Technician (Cat ET) on one of our 3500 series engines, Hawthorne Marine Power stocks the parts vital to your operation. Our goal is to help you minimize your downtime and get back to generating revenue. It all starts with having dedicated parts personnel with an in-depth knowledge of the commercial fishing industry. Furthermore, we stock new and Cat remanufactured water pumps, cylinder heads, cylinder packs, fuel injectors, fuel transfer pumps, turbo cartridges, gasket kits and so many more parts commonly used on today’s fishing vessels and skiffs.

We know that managing your maintenance costs is a critical component of your commercial fishing operation.  This is why we also offer Cat remanufactured parts. Carrying the same one-year part warranty as new parts, Cat remanufactured parts maintain the same high level of quality and dependability you have come to expect from Cat replacement parts at an overall reduced cost. Cat remanufactured parts give you some welcomed financial flexibility when you need it.

If you are the port engineer responsible for keeping your fleet fishing, you have a lot to manage. Hawthorne Marine Power wants to partner with you, so your parts procurement is one less thing for you to worry about. From San Diego to Saipan, we have got you covered!

Have a good rebuildable core and in the market for a swing engine? Let Hawthorne Marine Power veteran service team build one up for you. Or, perhaps you have an engine with high hours in need of an overhaul? Nothing gives you the confidence of knowing that your Cat engine was overhauled by factory-trained technicians, using factory-certified parts done the right way, with no shortcuts. We cap it all off with post-overhaul break-in testing and tuning at our in-house Dyno facility. Your engine will be run-in and ready to be put back into service upon arrival.
