CENTER STATE ENGINE REMANUFACTURING PROCESS
Anybody with a wrench and an engine stand can sell a "remanufactured engine". What differentiates our remanufactured marine engines from the competition? Let's take a look:
To make as close to new as possible. Wearable parts are automatically replaced. All core material is closely inspected and checked against original equipment specifications for correct dimensional tolerances. Replacement parts are new and made in the same production process as original equipment.
Testing is performed to manufacturer specifications and original production standards. Choose for yourself, but know that Center State Engine Exchange will only provide completely remanufactured engines — or any of our other remanufactured components — and that you can drive away from your technician's shop with confidence if you have an Center State Engine Exchange engine in your boat.

Center State Engine's "10-Step" Remanufacturing Process
To make as close to new as possible. Wearable parts are automatically replaced. All core material is closely inspected and checked against original equipment specifications for correct dimensional tolerances. Replacement parts are new and made in the same production process as original equipment.
Testing is performed to manufacturer specifications and original production standards.

Step 1: Before cores are disassembled, we inspect each and every one and scrap any cores that are corroded in any manner that will prevent the engine from being just as durable as the new engines from the factory. Marine engines have to be tougher than your standard engine - we know this and choose only the best blocks, typically those used soley in fresh water.
Step 2: Tear Down – Cores are taken apart completely.
Step 3: Oven Cleaning - Engine blocks and crankshafts are put through an oven to remove any particles of residue left over from core material.
Step 4: Steel Shot Cleaning - Engine blocks are run through a steel-shot machine, for about 30 minutes each. This cleans the block further and removes any more residue left over from core material.
Step 5: Cleaning – engine blocks and other core material are cleaned. Core material is run through an ultrasonic cleaner.
Step 6: Machining – Engine blocks are bored, decked (resurfaced), and blueprinted to OEM specifications on a Rottler CNC machine. After this process the engine block is more precise than factory new.
Step 7: Honing - Engine blocks are honed in a Rottler automated hone using diamond stones.
Step 8: Cleaning - Engine blocks are cleaned after CNC machining and honing.
Step 9: Assembly – engines are assembled as base engine (longblocks with tin) and are ready to be tested on our Simm Test machine.
Step 10: Testing – engines are tested on a Simm Test machine, where they are spun to 1000 RPM's, primed, and comnpression tested and checked for oi
