Tri Star marine engines are purpose built marine engines that meet or exceed OE specifications. These engines use brass plugs, marine specific gaskets, marine cams, and hypereutectic pistons.

Don't be fooled by engine builders using inferior non-marine grade parts for lower prices. The engine professionals at Tri Star have been building inboard and IO engines for all types of boats since 1988. These GM 8.2L 502CID OE marine replacement engines come with a 24 month warranty and are completely pre tested before shipment.

When you purchase a remanufactured engine from Tri Star you know you're getting the best quality, corrections for original equipment design flaws, and an industry leading nationwide warranty.

Remanufactured marine engines Vs. Rebuilt marine engines: Every engine from Tri Star is remanufactured, not rebuilt. Remanufacturing marine engines includes machining all parts including block, crank, rods, cylinder heads and assembling the engine with new parts.

Rebuilt marine engines will only correct the issue with the old "core" engine, but will often not include manufacturing of the rest of the engine. Rebuilt 8.2L marine engines are inferior quality and usually do not include marine grade parts. When shopping be sure to ask if you're getting a rebuilt 8.2 502CIDmarine engine, or a 100% remanufactured GM 8.2L 502CID marine engine.
