All of our GM replacement engines are made specifically for marine application; for example at Tri Star we use marine specific cams, forged or hypereutectic pistons and brass frost plugs in every marine engine we sell. Don't be fooled by lower prices that claim to be marine engines with lower grade components.

All Tri Star marine replacement engines are remanufactured with the highest quality control. All specifications meet or exceed standards set by OE and engine remanufacturing guidelines, and every engine is thoroughly tested prior to packaging. Buying this Tri Star 5.7L Marine Engine ensures long engine life for the best price.
