For 2008 Indmar's Saltwater Specific 5.7L HO SS inboard now features Indmar's ETC system (Electronic throttle and cruise) now standard. The Indmar developed system allows the helm throttle control to electronically connect to the engine's ECM. Throttle response is quick and smooth. The Electronic Throttle Control With Cruise feature is a bonus for everyone from cruising families to fishermen, wake boarders to water skiers.

The Indmar 5.7L HO SS is a multi-port EFI inboard engine marinized specifically for saltwater applications, such as bay runabouts, small cruisers, sportfish and workboats.

All 2008 5.7L HO SS's feature the patented one-piece ETX/CAT (Extreme Tuned Exhaust with Catalyst). The most dramatic achievement for boater safety is ETX/CAT's substantial reduction of Carbon Monoxide (CO) gases in all part-throttle operating modes. Neither the California Air Resources Board (CARB) nor the Environmental Protection Agency (EPA) currently regulates CO emissions, but when they do Indmar is ready to meet or surpass those regulations.

There is no measurable engine power loss thanks to ETX/CAT's extreme tuned manifold/catalyst design. The ETX/CAT system is a free breathing, header style performance exhaust manifold designed to incorporate the catalytic converter as a compact assembly.

Certified: 4-Stars Super Ultra-Low Emission by California Air Resources Board 2007.

Add an Indmar-designed torque-tuned multi-port intake manifold, GM's high-flow Vortec heads and a high-lift roller cam for even more performance.
