About Our Marine Extended Base Engines
We take the new base engines provided to us by GM Marine and build them up with OE parts or high quality aftermarket parts to suit customer's needs. Why buy and intake separatly from an engine? Why not get it delivered with necessary accessories already installed? That's what Marine Engines 4 Less is here to do. We sell preset Extended base engines or allow customers to build their own engine from the base up. To build your own base engine, click here
GM has been at the forefront of marine engine design for over 40 years, introducing new technologies that have improved performance, fuel efficiency, emissions, and overall customer satisfaction. Technologies like Variable Valve Timing (VVT), Active Fuel Management (AFM), E85 FlexFuel capable, Returnless Fuel Injection, Electronic Throttle Control, Advanced Ignition systems, Direct Injection (DI), and charged air systems have been introduced on our world-class cars and trucks and could be considered for marine engine applications, as well.
Today, GM provides the most complete marine engine portfolio to all of the major marinizers in North America, with a major share of the gasoline stern drive and inboard marine engine market.
The same engine that powers your GM truck or SUV is specialized to create the unparalleled performance you can expect in a GM marine engine.
GM Powertrain has designed a number of important features into its marine engines, such as corrosion-resistant alloys, engine oil sealing system, marine-specific camshaft designs for some applications, and cooling systems that are compatible with both salt and fresh water environments.
Because GM Powertrain knows the tremendous demand put on engines in the marine environment, GM marine engines are "tested tough" by being run at extensive wide-open throttle conditions, under load, when subject to the Marine GED Test Schedule (Global Engine Durability).
