New 5.7L Pre-Vortec Marine Base Engine (replaces years 1987-1995)
This is a brand new 5.7L/350 c.i. Vortec Marine Base Engine right out of GM Marine. This engine will replace those 5.7L marine engines used in Mercruiser, Volvo Penta, OMC, Crusader, Indmar and other applications between the years 1987-1995 that utilized the 12-bolt intake manifold, has center bolt valve covers, and a one piece rear main seal.
This is a perfect stock replacement for those engines that have suffered from a cracked block due to improper winterization or another type of engine failure.
If your engine is using a mechanical fuel pump, you will need to convert to an electric fuel pump to utilize this new pre-vortec engine.

About Our Marine Base Engines
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).
