New 4.3L Vortec Marine Base Engine (replaces years 2008-newer)

This is a brand new 4.3L/262 c.i. Vortec Marine Base Engine right out of GM Marine. This engine will replace those 4.3L marine engines used in Mercruiser, Volvo Penta, OMC, Crusader, Indmar and other applications between the years 2008-newer. This will replace the 4.3's with the aluminum timing cover.

We offer this “build your own” marine engine option for people who are not interested in one of our preselected extended base engine options.

 

How to build your own 4.3L Vortec Engine:

Start: we’ll start with the base engine (longblock with valve covers, timing cover, oil pan, and harmonic balancer)

Next: select from a list of components from the drop down options. The price will change with each option selected or deselected.

Next: click the “Add to Cart” button when you’re ready to purchase the engine.

Finalize: you’ll get a confirmation email when you’re done purchasing your custom built engine. Please allow 3-5 business days for the engine to be assembled with your selected accessories. We’ll then ship your engine crated to the address provided by truck freight.

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).

 

About Our Accessories

We use only engine accessories that we have tested here at our facility. No one wants accessories installed on an engine that won’t hold up in the long run. It’s just a headache for you and us alike.

Accessories will vary by brand depending on what options you choose when building your engine. Our carburetors are either Edelbrock or Holley, or intakes are either Edelbrock, Indmar or OE. Ignition systems are Delco. Exhaust setups are either GLM or BARR.
